Chapter 1: 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.
1.1Single 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.

SINGLE PHASE SYSTEM |
CHAPTER 1: AC POWER MEASUREMENT |
The power (W) in a single phase system is:
W = E • I • cosΘ
E = potential, I = current, and cosΘ = phase difference between the potential and the current.
Power in a 120/240V AC system is:
W = (ELine 1 • ILine 1 • cosΘ) + (ELine 2 • ILine 2 • cosΘ)
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: .
VAR = E I sinΘ
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:
Reactive
Apparent Power (VA) Power
(VAR)
Real Power (W)
FIGURE 1–2: Relationship between apparent, real and reactive power
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).

CHAPTER 1: AC POWER MEASUREMENT |
THREE-PHASE SYSTEM |
1.2Three-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:

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).

CONSUMPTION, DEMAND AND POOR POWER FACTOR |
1.3Consumption, Demand and Poor Power Factor
CONSUMPTION: WH = W × T
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 specified 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 |
1.4Waveform 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.
SINUSOIDAL WAVEFORM:
DISTORTED WAVEFORM:
A • sin (ω t)
A • sin(ω • t) + A1 • sin(ω1 • t) + A2 • sin(ω2 • t) + A3 • sin(ω3 • t) +L
TOTAL HARMONIC DISTORTION (THD):
% of THD = |
RMS of Total Harmonic Distortion Signal |
× 100 |
|
RMS of the Fundamenta l Signal |
|||
|
|
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.

Installation
3.1Connecting the Current Circuit
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.

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 CONNECTION |
CHAPTER 3: ELECTRICAL INSTALLATION |
3.2CT 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.
CTs are shorted if connected to the terminal block model DSP2 or 3 even if it is detached from the meter.
3.2.1Helpful 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
ZKW reading. It should be positive.
ZIf negative, reverse the CT wires on terminals 8 and 9.
ZConnect terminal number 6 potential. If KW decreases to about zero, reverse CT wires on terminals 10 and 11.
ZConnect terminal number 7 potential. If KW is one-third of expected reading, reverse CT wires to terminals 12 and 13.

CHAPTER 3: ELECTRICAL INSTALLATION |
CONNECTING THE VOLTAGE CIRCUIT |
3.3Connecting 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 |
3.4Selecting 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.

3.6Electrical Connection Installation
Choose the diagram that best suits your application and maintain the CT polarity. Follow the outlined procedure to verify correct connection.
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 |
3.8Relay, Protection and Pulse Output
(This section applies only to the -NL or -NL2 Relay Option.)
3.8.1EPM 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.
3.8.22 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.

FIGURE 3–9: Close-up of the Relay and KYZ pulse output on the rear panel.
Note: The relays shown in the figure above are in the NOT energized state.
The instrument detects two levels of alarm for the following functions:
•Voltage: AN, BN, CN, AB, BC, CA
•Current: A, B, C, N
•Over and Reverse Power
•Under PF/KVAR Lead or Lag
•Over KVA
•Voltage Imbalance (One level only)
•Over/Under Frequency
•Voltage Phase Reversals (One level only)
•Over/Under %THD (Available only with option –H)
•Over/Under K-Factor
KYZ RELAYS: Provides pulses for energy management systems or any other type of recording device. These pulses represent accumulated watt-hour, negative watt-hour, or VA-hour. Accomplish this assignment through the Programming Mode (see programming sections). The pulse value is determined by the decimal increment of the power function assigned to the pulse. The EPM 5200P can be equipped with KYZ pulse outputs.
Unless otherwise specified, standard KYZ setup represents positive watt hour. See table below for standard rate. The scale factor for wattage (KW or MW) and Full Scale Decimal Point Placement is selectable in Programming Mode GROUP 1, FUNCTION 2. Follow the Decimal Point Placement corresponding to the Change in Level. A multiplication or division factor can be programmed. See Programming GROUP 0, FUNCTION 6 for a different rate.
