1.1 Introduction to the PQMII
1.1.1 Description
The GE Multilin PQMII Power Quality Meter is an ideal choice for continuous monitoring of a
single or three-phase system. It provides metering for current, voltage, real power, reactive
power, apparent power, energy use, cost of power, power factor, and frequency.
Programmable setpoints and four assignable output relays allow control functions to be
added for specific applications. This includes basic alarm on over/under current or voltage,
unbalance, demand-based load shedding, and capacitor power factor correction control.
More complex control is possible using the four switch inputs; these can also be used for
status information such as breaker open/closed and flow information.
As a data gathering device for plant automation systems that integrate process,
instrument, and electrical requirements, all monitored values are available via one of two
RS485 communication ports running the Modbus protocol. If analog values are required
for direct interface to a PLC, any of the monitored values can output as a 4 to 20 mA (or 0
to 1 mA) signal to replace up to four (4) separate transducers. A third RS232
communication port connects to a PC from the front panel for simultaneous access of
information by other plant personnel.
With increasing use of electronic loads such as computers, ballasts, and variable
frequency drives, the quality of the power system is important. With the harmonic analysis
option, any phase current or voltage can be displayed and the harmonic content
calculated. Knowledge of the harmonic distribution allows action to be taken to prevent
overheated transformers, motors, capacitors, neutral wires, and nuisance breaker trips.
Redistribution of system loading can also be determined. The PQMII can also provide
waveform and data printouts to assist in problem diagnosis.

PQMII POWER QUALITY METER – INSTRUCTION MANUAL 1–5
1.2 Standard Features
1.2.1 Metering
True RMS monitoring of Ia, Ib, Ic, In, Van, Vbn, Vcn, Vab, Vbc, Vca, voltage/current
unbalance, power factor, line frequency, watts, vars, VA, Wh, varh, VAh, and demand
readings for A, W, vars, and VA. Maximum and minimum values of measured quantities are
recorded and are date and time stamped.
A 40-character liquid crystal display is used for programming setpoints and monitoring
values and status.
1.2.2 Alarms
Alarm conditions can be set up for all measured quantities. These include overcurrent,
undercurrent, neutral current, current unbalance, voltage unbalance, phase reversal,
overfrequency, underfrequency, power factor, switch inputs, etc. The alarm messages are
displayed in a simple and easy to understand English format.
1.2.3 Communications
The PQMII is equipped with one standard RS485 port utilizing the Modbus or DNP
protocols. This can be used to integrate process, instrumentation, and electrical
requirements in a plant automation system by connecting several PQMII meters together
to a DCS or SCADA system. A PC running the EnerVista PQMII Setup Software can change
system setpoints and monitor values, status, and alarms. Continuous monitoring
minimizes process downtime by immediately identifying potential problems due to faults
or changes from growth.
The PQMII also includes a front RS232 port which can be used for the following tasks:
• data monitoring
• problem diagnosis
•viewingeventrecords
•trending
• printing settings and/or actual values
• loading new firmware into the PQMII
1.2.4 Future Expansion
Flash memory is used to store firmware within the PQMII. This allows future product
upgrades to be loaded via the serial port.

1.2.5 Open Architecture
PQMII units can initially be used as standalone meters. Their open architecture allows
connection to other Modbus compatible devices on the same communication link. These
can be integrated in a complete plant-wide system for overall process monitoring and
control.

CHAPTER 1: OVERVIEW
PQMII POWER QUALITY METER – INSTRUCTION MANUAL 1–7
1.3 Optional Features
1.3.1 Transducer Input/Outputs
Four isolated 4 to 20 mA (or 0 to 1 mA depending on the installed option) analog outputs
are provided that can replace up to eight transducers. The outputs can be assigned to any
measured parameters for direct interface to a PLC.
One 4 to 20 mA analog input is provided to accept a transducer output for displaying
information such as temperature or water level.
An additional rear RS485 communication port is provided for simultaneous monitoring by
process, instrument, electrical, or maintenance personnel.
FIGURE 1–4: Additional Communication Port
1.3.2 Control Option
An additional three dry-contact form “C” output relays and four dry-contact switch inputs
are provided. These additional relays can be combined with setpoints and inputs/outputs
for control applications. Possibilities include:
• undercurrent alarm warnings for pump protection
• overvoltage/undervoltage for generators
• unbalance alarm warnings to protect rotating machines
• dual level power factor for capacitor bank switching
• underfrequency/demand output for load shedding resulting in power cost saving
• kWh, kvarh and kVAh pulse output for PLC interface
• Pulse input for totalizing quantities such as kWh, kvarh, kVAh, etc.

1.3.3 Power Analysis Option
Non-linear loads (such as variable speed drives, computers, and electronic ballasts) can
cause unwanted harmonics that may lead to nuisance breaker tripping, telephone
interference, and transformer, capacitor or motor overheating. For fault diagnostics such
as detecting undersized neutral wiring, assessing the need for harmonic rated
transformers, or judging the effectiveness of harmonic filters, details of the harmonic
spectrum are useful and available with the power analysis option.

CHAPTER 1: OVERVIEW
PQMII POWER QUALITY METER – INSTRUCTION MANUAL 1–9
Voltage and current waveforms can be captured and displayed on a PC with the EnerVista
PQMII Setup Software or EnerVista Viewpoint. Distorted peaks or notches from SCR
switching provide clues for taking corrective action.
FIGURE 1–7: Captured Waveform
Alarms, triggers, and input/output events can be stored in a 150-event record and time/
date stamped by the internal clock. This is useful for diagnosing problems and system
activity. The event record is available through serial communication. Minimum and
maximum values are also continuously updated and time/date stamped.
