Chapter 1: AC Power

AC Power Measurement

The economics of electric power distribution networking dictate several configurations of AC power transmission. The number of phases and voltage levels characterize these configurations.

Measurement

1.1 Single Phase System

A single phase system is a basic two-wire system used in low power distribution applications, such as residential communities or offices. Typically, the voltage is 120V AC. For higher power requirements, such as small commercial facilities, the typical power configuration is two lines of 120V AC opposite in phase (see Figure 1.1 B, below).

This system produces 120 volts from line to neutral for lighting and small appliance use. The line-to-line voltage is 240V AC, used for higher loads such as water heaters, electric dryers, ranges and machinery.

EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL 1–1

SINGLE PHASE SYSTEM CHAPTER 1: AC POWER MEASUREMENT

The power (W) in a single phase system is:

Θcos • I • E = W

E = potential, I = current, and cosΘ = phase difference between the potential and the current.

Power in a 120/240V AC system is:

)cos • I • (E + )cos • I • (E = W

ΘΘ

2 Line2 Line1 Line1 Line

Phase differential between the potential and the current results from a non-resistive load, either reactive or capacitive.

Reactive power (VAR): The additional power consumed that does not produce any work but must be delivered to the load: .

Θ⋅⋅ insIE=VAR

This is a measure of the inefficiency of the electrical system.

Apparent power (VA): The total power delivered to the load, and the vector sum of real power and reactive power.

Power Factor (PF): The ratio between real power and apparent power:

Apparent Power (VA)

Real Power (W)

FIGURE 1–2: Relationship between apparent, real and reactive power

Reactiv Power (VAR)

Ideal power distribution should have a PF of 1. This condition can be met only if no reactive power loads exist. In real life applications, many loads are inductive loads. Often, corrective capacitors are installed to correct Poor Power Factor (see Section 1.3).

1–2 EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL

CHAPTER 1: AC POWER MEASUREMENT THREE-PHASE SYSTEM

1.2 Three-Phase System

A three-phase system delivers higher levels of power for industrial and commercial applications; the three phases correspond to three potential lines. A 120° phase shift exists between the three potential lines.

A typical configuration has either a Delta connection or a Wye connection (see Figure 1.3, below).

In a three-phase system, the voltage levels between the phases and the neutral are uniform and defined by:

=====

1) Delta

FIGURE 1–3: Three-Phase System: (1) Delta, (2) Wye

Voltages between the phases vary depending on loading factors and the quality of distribution transformers. The three-phase system is distributed in different voltage levels: 208V AC, 480V AC, 2400V AC, 4160V AC, 6900V AC, 13800V AC, and so on.

Power measurement in a poly phase system is governed by Blondel's Theorem. Blondel’s Theorem states that in a power distribution network which has N conductors, the number of measurement elements required to determine power is N-1. A typical configuration of poly phase system has either a Delta connection or a Wye connection (see Figure 1.4, below).

CHAPTER 1: AC POWER MEASUREMENT CONSUMPTION, DEMAND AND POOR POWER FACTOR

1.3 Consumption, Demand and Poor Power Factor

CONSUMPTION:

W = instantaneous power T = time in hours

The total electric energy usage over a time period is the consumption of WH.

Typically, the unit in which consumption is specif ied is the kilowatt-hour (KWH): one thousand watts consumed over one hour. Utilities use the WH equation to determine the overall consumption in a billing period.

DEMAND: Average energy consumed over a specified time interval. The utility determines the interval, typically 15 or 30 minutes. The utility measures the maximum demand over a billing period. This measurement exhibits a deviation from average consumption, causing the utility to provide generating capacity to satisfy a high maximum consumption demand. The highest average demand is retained in the metering system until the demand level is reset.

POOR POWER FACTOR: Results in reactive power consumption. Transferring reactive power over a distribution network causes energy loss. To force consumers to correct their Power Factor, utilities monitor reactive power consumption and penalize the user for Poor Power Factor.

WAVEFORM AND HARMONICS CHAPTER 1: AC POWER MEASUREMENT

1.4 Waveform and Harmonics

Ideal power distribution has sinusoidal waveforms on voltages and currents. In real-life applications, where inverters, computers, and motor controls are used, distorted waveforms are generated. These distortions consist of harmonics of the fundamental frequency.

HARMONIC DISTORTION: A destructive force in power distribution systems. It creates safety problems, shortens the life span of distribution transformers, and interferes with the operation of electronic devices. The Futura+ monitors the harmonic distortion to the 31st harmonic. A waveform capture of distorted waveform is also available.

Electrical Installation

3.1 Connecting the Current Circuit

Installation

Install the wiring for the current at 600V AC insulation as a minimum. The cable connector should be rated for 6 Amps or greater and have a cross-sectional area of 16 AWG minimum.

Mount the current transformers (CTs) as close as possible to the meter for best accuracy. The following table illustrates the maximum recommended distances for various CT sizes, assuming the connection is via 16 AWG cable.

Table 3–1:

CT Size Maximum Distance (CT to Meter)

2.5 VA 10 Feet

5.0 VA 15 Feet

7.5 VA 30 Feet

10.0 VA 40 Feet

15.0 VA 60 Feet

30.0 VA 120 Feet

DO NOT leave secondary of the CT open when primary current is flowing. This causes high voltage that will overheat the secondary of the CT. Use a shorting block on the secondary of the CT.

CT Size and Maximum Distance

EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL 3–5

CT CONNECTION CHAPTER 3: ELECTRICAL INSTALLATION

3.2 CT Connection

If the meter is connected directly to the current (up to 10 Amps max.), maintain the exact connection to avoid incorrect polarity.

When the meter is connected using the CTs, you must maintain the correct CT polarities. CT polarities are dependent upon correct connections of CT leads, and upon the direction the CTs are facing when clamped around conductors. The dot on the CT must face the line side; the corresponding secondary connection must connect to the appropriate input on the meter. Failure to connect CTs properly results in inaccurate power readings. If your meter is not reading power properly, it is more than likely the CT is incorrectly wired.

Note

CTs are shorted if connected to the terminal block model DSP2 or 3 even if it is detached from the meter.

3.2.1 Helpful Debugging Tools

Option 1: Isolating a CT Connection Reversal power reading

If your meter does not read the correct watts after installation, it almost always means that the CT’s have been wired in the wrong polarity. To check the polarity of the CT after the monitor has been installed, look at the single phase WATT readings to see that each of the readings are positive (assuming you are consuming power). If one of the WATT readings is negative, that particular phase CT is reversed.

To check the single phase WATT reading, press the Power button twice while the annunciator is positioned to WATTS. Then press the Phase/Next button to cycle through the phases. After connecting the polarity of the CTs, the WATT and VAR readings should be correct.

Option 2: Isolating a CT Connection Reversal using Voltage Readings

Z KW reading. It should be positive.

Z If negative, reverse the CT wires on terminals 8 and 9.

Z Connect terminal number 6 potential. If KW decreases to about

zero, reverse CT wires on terminals 10 and 11.

Z Connect terminal number 7 potential. If KW is one-third of

expected reading, reverse CT wires to terminals 12 and 13.

3–6 EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL

CHAPTER 3: ELECTRICAL INSTALLATION CONNECTING THE VOLTAGE CIRCUIT

3.3 Connecting the Voltage Circuit

For proper meter operation, the voltage connection must be maintained. The voltage must correspond to the correct terminal.

The cable required to terminate the voltage sense circuit should have an insulation rating greater than 600V AC and a current rating greater than 0.1 A.

EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL 3–7

SELECTING THE VOLTAGE FUSES CHAPTER 3: ELECTRICAL INSTALLATION

3.4 Selecting the Voltage Fuses

We strongly recommend using fuses on each of the sense voltages and the control power, although connection diagrams do not show them. Use a 1 Amp fuse on each voltage input .

The meter can handle a maximum voltage of 150V phase to neutral. PTs are required for higher voltages. Suffix -G extends the maximum direct voltage to 300V phase to neutral, 600 volt phase to phase.

Control Power and Current

Note

For DC-powered units, polarity should be observed. Connect the negative terminal to L and positive terminal to L1. An earth ground connection to chassis is mandatory for normal operation (terminal three). Do not ground the unit through the negative of the DC supply.

Note

Externally fuse power supply with a slow-blow 3 Amp fuse.

EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL 3–9

ELECTRICAL CONNECTION INSTALLATION CHAPTER 3: ELECTRICAL INSTALLATION

3.6 Electrical Connection Installation

Choose the diagram that best suits your application and maintain the CT polarity. Follow the outlined procedure to verify correct connection.

Note

IMPORTANT: For PT connections only, short terminals 3 and 4.

Connect local ground to terminal 3. This protects the unit from spikes and transients.

• The meter and terminal module DSP3 are factory calibrated together; the serial numbers are matched on both. The DSP3 input module and the meter base MUST MATCH!

• Mismatching of the meter and DSP3 input module will cause inaccurate readings because calibration ratios are stored in the meter’s memory, not in the DSP3 input module.

RELAY, PROTECTION AND PULSE OUTPUT CHAPTER 3: ELECTRICAL INSTALLATION

3.8 Relay, Protection and Pulse Output

(This section applies only to the -NL or -NL2 Relay Option.)

3.8.1 EPM 5300P Relay Overview

The EPM 5300P offers dry contact relay output capability. The EPM 5200P only offers KYZ pulse outputs and cannot be configured to trip contacts on events.

FAIL-SAFE MODE: The EPM 5300P -NL option gives the user an adjustable tripping bandwidth. The user specifies a range over which functions, such as frequency, phase relation and voltage, are acceptable. The relay releases during times of normal operation, and engages when functions are outside specified normal levels. The relay can be programmed to engage during normal operating conditions, and release outside specified normal range (particularly when power is lost). This is the fail-safe mode.

HYSTERISIS: The EPM 5300P -NL option also includes adjustable hysterisis. In addition to a time delay on activating any contact, the user may specify a lower level to release the relay, rather than releasing after the initial alarm point. This is ideal during load shedding when an alarm activates at a certain level and the user does not want to turn off the alarm until a much lower, safer level.

SETABLE DELAYS: After reaching the alarm point, a change in relay status may be delayed for 255 seconds. The user also has the option of allowing the device to change relay status without any delay. After the alarm condition passes, the relay can be stopped from returning to a normal condition for a programmable time. Each delay time is independent of one another.

AND/OR LOGIC: If several parameters are assigned to one relay, the user can trip the relay if all functions are out of limit (and programming), or if one function is out of limit (or programming). For example, if limits on Voltage, Kilowatts, and Phase Imbalance are programmed and tied to Relay 1, the user can either trip the relay if one function is out of limit, or if all functions are out of limit.

3.8.2 2 Relays & 1 KYZ Pulse Output -NL OPTION

The EPM 5300P's flexibility accesses a variety of relay options through the Programming Mode (see programming sections). The relay option package consists of three relays: two can be dedicated to alarm or controlled through communication (or both) and one for KYZ pulse output.

If the relays are controlled through communication, there are two different modes:

• Lock ON: Relay will not be affected by any alarm condition.

• Lock OFF: Relay will not be affected by any alarm condition.

If the relays are used for communication and alarm, there are four different modes:

• Lock ON: Relay stays on regardless of any alarm condition.

• Lock OFF: Relay stays off regardless of any alarm condition.

• Free ON: Relay turns on unless other conditions force it off.

• Free OFF: Relay turns off unless other conditions force it on.

CHAPTER 5: OVERVIEW ACCESSING MAX/MIN VALUES

5.5 Accessing Max/Min Values

Max/min values represent the highest and lowest average demand over a user programmable time period known as the Integration Interval. The readings are calculated using a rolling average technique. Each second, a new reading is used to calculate the max/min; the last reading of the interval is dropped off. The highest max during an averaging period is stored until the user resets the max/min. This is similar to amp demand meters. It is commonly referred to as Thermal Demand.

To access a max/min value while displaying a desired measurement, press MAX/MIN/ LIMITS—once for the max value; twice for the min. Examples given below are for voltage and current phases. Use the same procedure for all other parameters.

VOLTAGE PHASE REVERSAL AND IMBALANCE CHAPTER 5: OVERVIEW

5.9 Voltage Phase Reversal and Imbalance

In a three-phase power distribution system, normal phase shift between each line is 120°. If the EPM 5300P detects an abnormality, it displays a message of PH. The EPM 5200P does not have this feature.

VOLTAGE PHASE REVERSAL: If there is an incorrect connection, such as mistaking line A for line B, a PH message appears. The correct sequence is a-b-c.

VOLTAGE PHASE IMBALANCE LIMIT: This is detected using the phase imbalance limit in the Programming Mode. The phase imbalance is expressed as a percentage, with 0% indicating a 120° phase shift between each line. A PH message appears if the limit is exceeded.

MODBUS PLUS CAPABILITY CHAPTER 9: PROGRAMMING GROUP 0 - GLOBAL METER SETUP

9.4 Modbus Plus Capability

When using the MPI Modbus Plus adapter, the meter values should be set to speak to Modbus RTU with a meter address of 0001 and a baud rate of 9600 baud. The Modbus Plus address is programmed into the MP1 Modbus Plus adapter directly.

9.4.1 Printing Option

To print, access Mode 1 and Mode 2 (see Part I: Installation and Operation). Printing serial options should be disabled when using a multimeter communications connection RS485.

DISABLING PREVENTS:

1. Printing through the keypad.

2. Corrupting data at a computer terminal while multiple meters poll.

3. Corrupting printing commands through communications.

This option connects a serial printer to the RS232 port and prints the data. Disable this feature when the meter is not using an RS232 port (i.e., when RS485 or DC outputs are being used).

9.7 Group 0, Functions 4–5—Time Delay for Relays 1 & 2 (Option – NL)

GROUP 0, FUNCTIONS 4–5 sets the time delay for Relays 1 and 2 between 0 and 255 seconds. This allows conditions (example below) to exist for a userspecified time period before the relay or alarm activates. If a time greater than 255 seconds is entered, the meter defaults to the maximum value of 255 seconds.

Example: If Relay 1 is set for 300 amps and the amps increase to 301, the Relay trips only after a programmed delay period. If the meter then measures 299 Amps, the Relay returns to its original position, after the programmed delay.

Relay 1: Located in 04.0 & 04.1.

Relay 2: Located in 05.0 & 05.1.

(Procedures for both relays are the same).

Group 1 – Voltage, Amp And Watt Scale Settings

Programming Group 1 – Voltage, Amp And Watt Scale Settings

Note

The EPM 5300P and 5200P full scales will already be programmed if the order specified current and voltage transformer ratios. The meter label indicates any full scale setup.

Programming Group 1 contains voltage, amperage and full scale power selection, along with scale factor selection and decimal point placement.

The user can re-scale without removing the EPM 5300P for calibration. The 5300P has been calibrated at standard levels in GROUP 2. Mathematically convert any full scale ratios to those calibrated levels. If a different current or voltage transformer is used, program the primary value of its ratio. If necessary, convert the ratio to a secondary value of five amps standard current (1 amp is a special order) and 120V or 75V nominal voltage (options L only).

Formulas:

Primary

Secondary

It may be necessary to convert the full scale to a larger unit. There is a resolution limitation for all full scales of 2000. If a display reading exceeds 2000, it may be unstable and subject to zeroing problems.

Example: The full scale for a CT ratio of 3000/5 should be 03.00 kA.

When changing a PT or CT full scale, calculate the new watts full scale and make any necessary changes. The watts full scale will not auto range.

CHAPTER 10: PROGRAMMING GROUP 1 – VOLTAGE, AMP AND WATT SCALE SETTINGS GROUP 1, FUNCTION 2

10.3 Group 1, Function 2

- SCALE SELECTION AND DECIMAL PLACEMENT FOR WATTS -

Programming GROUP 1 also provides decimal positioning for maximum resolution. The following examples assist in selecting the best decimal position for FUNCTION 2.

Note

Shift the decimal left to increase resolution. Wattage should not exceed a numeral value of 2500. Shift the decimal one position right to decrease resolution.

Full Scale Wattage (FSW) is the product of FSV and FSA. For FSW for three phases multiply the FSW per phase by 3.

Example 1: Full Scale Voltage (FSV)=120 V

Full Scale Amperage (FSA)=5.00 A

FSW (one phase) =120 Vx5.00 A

FSW (one phase)=600 W

FSW (three phase)=600 Wx3 = 1,800 W

Here the FSW is too small a value for a Megawatt meter. FSW in the Kilowatt meter equals

1.800 KW. In FUNCTION 2, four 9s appear. Place the decimal point after the first digit. The

user cannot change the four digits. The user can only move the decimal point placement.

Example 2: 480/120 PT, 1000/5 CT

FSV=480 V

FSA=1000 A

FSW (one phase)=480 V ⋅ 1000 A

FSW (one phase)=480,000 W

⋅

FSW (three phase)=480,000 W

3 = 1,440,000 W

FSW for a Kilowatt meter equals 1440. KW. FSW for a Megawatt meter equals 1.440 MW. In FUNCTION 2 place the decimal point after the last digit for a Kilowatt meter and after the first digit for a Megawatt meter. It is important to note which type of bezel labeling you have when making this decision.

Example 3: 14.4 KV/120, 1000/5 CT

FSV=14.40 KV

FSA=1000 A

FSW (one phase)=14,400 Vx1000 A

FSW (one phase)=14,400,000 W

FSW (three phase)=14,440, 000 Wx3 = 43,200,000 W

FSW for a Kilowatt meter equals 43,200 KW. Here the FSW is too large a value for a Kilowatt meter (the range is 000–2500). FSW for a Megawatt meter equals 043.2 MW. In FUNCTION 2, place the decimal after the third digit .

Note

In some applications where the load is normally very low, the watts resolution can be increased by moving the decimal point one position left.

Programming Group 2 - Meter Calibration

WARNING—READ THIS SECTION CAREFULLY BEFORE PROCEEDING:

• Any rescaling, such as a change in a transformer ratio, can be accomplished in

GROUP 1. Calibration is not necessary.

• Meter calibration cannot be performed if the meter is installed for service. The

sensing inputs must be connected to a power supply with variable voltage and separate current outputs.

• The calibration procedure requires highly accurate and stable input signals.

Incorrect readings result from improper calibration procedures. If unsure, return unit to the factory for calibration.

• BEFORE calibrating any channel, make a note of its Full Scale Setting (see Chapter

10). Set the Full Scale in accordance with Table 10-2 for calibration. Restore original Full Scale Setting when calibration is completed.

Group 2 - Meter Calibration

EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL 11–83

CALIBRATION REQUIREMENTS CHAPTER 11: PROGRAMMING GROUP 2 - METER CALIBRATION

11.1 Calibration Requirements

Calibration on the EPM 5300P requires precise inputs of 120 Volts, 5 Amps, and 2.5 Amps. The EPM 5300P -G model requires precise inputs of 300 Volts, 5 Amps, and 2.5 Amps. If this equipment is unavailable, contact us for assistance.

Table 11–1: Group 2 Programming Format

Group and Function Number Function

20. High End Calibration—Volts AN, BN, CN

21. High End Calibration—Amps A, B, C

22. Low End Calibration—Amps A, B, C

2E. Exit Programming Group 2

Note

The voltage and current scales are calibrated with the maximum range value 2000 for current, 14.40 for voltage, 300 for option G. The calibration value can be identical to the full scale value in GROUP 1, for better accuracy than the specification. However, if a full scale is ever changed to a higher value than the calibrated value, the value may be less accurate.
