Introduction

GE Multilin has set a new standard in

metering technology with the introduction

of the PQM II.  This meter, designed on

the latest industry specifications, provides

accurate and reliable three-phase power

metering with an optional Ethernet and

fiber communications module in a small

and modern package. The PQM II  can

be used for a variety of applications

including metering of distribution feeders,

transformers, generators and motors.

robust Metering and Power Quality

Capabilities in one Package

Digital Metering

The PQM II is an ideal choice when

continuous monitoring of a three phase

system is required. It provides metering for

current, voltage, real and reactive power,

energy use, cost of power, power factor

and frequency. Waveform capture and

Voltage Disturbance Recorder continuously

monitors power quality. Programmable

setpoints and 4 assignable output relays

allow control functions to be added for

specific applications.

Communications Made easy

Integrate process, instrumentation

and electrical requirements in a plant

automation system by connecting PQM II

meters to a DCS or SCADA system. Meter

provides multiple communication ports that

can provide data simultaneously to multiple

masters such as SCADA, DCS, BMS etc.

Meter supports both ModBus and DNP 3.0

protocol. A computer running EnerVistaTM

software can change system setpoints,

monitor values, status and alarms.

Continuous monitoring minimizes process

downtime by immediately identifying

potential problems due to faults or

changes.

Industry leading software makes

setup simple

The PQM II comes complete with

EnerVistaTM GE Multilin's suite of software

tools for managing the entire lifecycle

implementation of the PQM II. EnerVistaTM

contains all of the tools for setting up and

configuring your PQM II in minutes via

RS232. RS485. external modem or Ethernet

LAN.

ethernet capability

With the optional Multinet module, users

can add Ethernet capability to their meter.

Multinet is an Ethernet communications

module that allows connection of up to 30

ModBus devices, providing ModBus TCP/IP

communications for these devices over

Ethernet. This allows connection to Fiber

Optic LAN and WAN systems for remote

access to data on the PQM II.

standard Features

The PQM II provides continuous monitoring

of a three-phase system. It provides

metering of current, voltage, real and

reactive power, energy use, cost of power,

power factor and  frequency. Ethernet

communications are available through the

optional Multinet module.

Metering

PQM II is a true RMS meter with 0.2%

accuracy for voltage and currents. The

PQM II provides advanced features for

monitoring and metering which include:

•    Ia        Ib            Ic            In

•    Va        Vb        Vc        Vab        Vbc        Vca
