Safety Considerations

Before installing and using this product, please read and understand the following precautions.

ATTENTION

Only qualified personnel, following accepted safety procedures, should install, wire and service the Powermonitor 3000 unit and its associated components. Before beginning any work, disconnect all sources of power and verify that they are de-energized and locked out. Failure to follow these instructions may result in personal injury or death, property damage, or economic loss.

Never open a current transformer (CT) secondary circuit with primary current applied. Wiring between the CTs and the Powermonitor 3000 unit should include a shorting terminal block in the CT secondary circuit. Shorting the secondary with primary current present allows other connections to be removed if needed. An open CT secondary with primary current applied produces a hazardous voltage, which can lead to personal injury, death, property damage, or economic loss.

IMPORTANT

Powermonitor 3000 Unit Operations

The Powermonitor 3000 unit is a microprocessor-based electrical power- and energy-measuring device. It connects to your three-phase or single-phase ac power system directly or through instrument transformers (PTs and CTs). It converts instantaneous voltage and current values to digital values, and uses the resulting digital values in calculations of things such as voltage, current, power, and energy. You may access the resulting metering values manually by using the display module or automatically by using communication with an external device or application.

The basic operations of the Powermonitor 3000 unit include the following:

Metering Functionality

• Metering functionality

• Operational and status indication

• Operation of the display module

• Display module menus and parameter structure

• Setup and configuration by using the display module

• Data monitoring by using the display module

• Issuing commands by using the display module

Other power monitor features such as communication, setpoint operations, I/O operations, data logging, oscillography, harmonics, sag/swell detection, load factor calculation, and transient detection are covered later in this manual.

The power monitor performs calculations on scaled, digital voltage and current values. Signals connected to the voltage and current inputs are sampled and their instantaneous values are converted to digital values in an analog-to-digital (A/D) converter section. These values are scaled according to configured PT Primary, PT Secondary, CT Primary, and CT Secondary parameters, and evaluated according to the configured Wiring Mode parameter. Metering results are available for display on the display module, in the communication data tables, and for use in setpoint programming and data logging.

Metering Accuracy Class

In the Selftest/Diagnostic Results table, element 26 is a read-only parameter that indicates the revenue metering accuracy class of the master module. If this element contains the value 0, the master module meets ANSI C12.16 and EN61036 Class 1 requirements for accuracy. If this element contains the value 1, the master module meets ANSI C12.20 Class 0.5, EN60687 Class 0.5, and Canadian standard CAN3-C17-M84 requirements for accuracy. If this element contains the value 2, the master module meets ANSI C12.20 Class 0.2, EN60687 Class 0.2, and Canadian standard CAN3-C17-M84 requirements for accuracy. The revenue metering accuracy class is also indicated on the side of the master module and can be accessed via the display module (DISPLAY > STATUS > ACCURACY CLASS).

Expressing Metered Data on the Display Module

The display module displays scaled metered data in its basic units, such as volts, amps, watts. Prefixes such as K or M are used to denote multipliers of 1,000 (kilo-) and 1,000,000 (mega-). The display module expresses power factor as a percentage, with a positive value indicating leading and a negative value indicating lagging.

The display module displays values to a maximum precision of five significant digits.

Viewing Metered Data by Using the Display Module

The display module makes it easy to view the metering data produced by the power monitor.

Refer to display module functionality later in this chapter for information on use of the display module.

Voltage, Current, and Frequency Results

Line-to-line voltage results (L1-L2, L2-L3, and L3-L1) are calculated for all wiring modes. Line-to-neutral voltage results (L1-N, L2-N, and L3-N) are calculated in wye and single-phase wiring modes only. In delta wiring modes, line-to-neutral voltages return a zero value.

Average line-to-line (Avg. L-L) and line-to-neutral (Avg. L-N) voltage results return the mathematical average of the three line-to-line or line-to-neutral voltages, respectively. For single-phase wiring modes, the average line-to-neutral voltage is the mathematical average of phase 1 to neutral (L1-N) and phase 2 to neutral (L2-N) voltages. Voltage results return 999 if the line-to-neutral voltage exceeds 347 volts.

Current results include individual phase current (L1, L2, L3) and average three-phase current. L4 current returns neutral or zero-sequence current (refer to symmetrical component analysis discussion below).

Frequency results include Last cycle frequency and Average Frequency, calculated over your selection of either one or the last eight cycles. Frequency results return 0 if either the frequency is less than 40 Hz or if the voltage magnitude on all three voltage inputs is too low. Frequency results return 999 if the frequency is greater than 75 Hz. The power monitor selects one voltage phase input for frequency calculations and automatically switches to another in case of a phase loss. Frequency source indicates which phase is used to calculate frequency results.

Frequency source is accessible only via communication.

Phase rotation returns a value indicating forward (ABC), reverse (ACB) or no rotation.

RMS Resolution and Averaging

There are a number of configuration options in the power monitor that affect metering results.

• RMS Resolution – the high-resolution setting provides more

accurate RMS results when significant levels of harmonics are present. You may also configure for nominal resolution if you require faster update rates but can accept lower accuracy as a trade-off. The M4 default is Nominal. The M5/M6/M8 default is High.

• RMS Result Averaging – the default setting provides a more

steady result by averaging the results of the last eight calculations. You may also configure no averaging for the fastest response to a changing signal.
