What is needed for PQ monitoring ?
GE Multilin’s solution
PQMII
EPM9000 series
Summary
3. PQ is a Business Problem Power Quality issues cause business problems such as:
Lost productivity, idle people and equipment
Lost orders, good will, customers and profits
Lost transactions and orders not being processed
Revenue and accounting problems
Customer and/or management dissatisfaction
Overtime required to make up for lost work time
4. Is Power Quality Such a Big Problem?
5. Why PQ is such a Big Problem? The sensitivity of today’s electronic equipment makes it susceptible to power disturbances
For some devices, a momentary disturbance can cause
scrambled data
interrupted communications
a frozen mouse
system crashes and equipment failure
6. PQ Problems are Expensive Berkeley Lab Study Estimates $80 Billion Annual Cost of Power Interruptions … Research News, Berkeley Lab, February 2, 2005
$50 billon per year in the USA is lost as a results of power quality breakdowns …. Bank of America Report
A manufacturing company lost more than $3 million one day last summer in Silicon Valley when the “lights went out.” … New York Times January 2000
“A voltage sag in a paper mill can waste a whole day of production - $250,000 loss” … Business Week, June 17,, 1996
Half of all computer problems and one-third of all data loss can be traced back to the power line … Contingency Planning Research, LAN Times

Interruptions
Sag/Under Voltage
Swell/Over Voltage
Waveform Distortion
Voltage Fluctuations
Frequency Variations

28. Power Quality Meter – PQM II
29. Key Features
High accuracy, mid range Power Quality with many advanced features.
Waveform capture using set-points for PQ analysis. Waveform can be triggered by external equipment (motors) through digital inputs for capturing start-up current etc….
Control Relays can open and close at the pre-programmed (min, max etc) set-points for alarms and notifications.
Analog outputs for power information to PLCs, RTU and other non digital communication devices.
VERY EASY to use , program and set-up – comes with free set-up and monitoring software (launch pad).
Voltage Disturbance Recording for electrical up to 500 sag & swell events
Open Modbus and DNP 3.0 protocol over RS 485 with multi port communication capability
Target Applications/Industries
Ideal for circuit monitoring for control panels, switchboards, Motor Control Centers, Power Distribution Panels.
Primary Monitoring of low and medium voltage application, requiring full metering with over 100 different electrical parameters with data logging and oscillograph (waveform).
Applications requiring Control Relays with set-point activation, Analog and digital I/Os.
Heavy power users for need of clean power - Data Centers, Pulp and Paper, Oil & Gas…….
OEMs, Electrical Panel Manufacturers, Switchgear manufacturers, Motor Control manufacturers….. Power Quality Meter – PQM II
31. Advanced PQ Meter – EPM 9000/9800 Key Features:
High Speed Waveform Recording - With up to 16 to 512 samples per cycle resolution. The unit records magnitude and duration of events including the captured waveform. All information is stored in the on-board mass memory.
Software and Hardware Triggers - The meters provides both software and hardware triggers to record waveform events. This allows the unit to be used for fault analysis, system apparatus monitoring and many other applications.
Extensive Harmonics Analysis – This meter provides a real- time harmonic analysis to the 128th order for every channel. This advanced harmonic recording capability has been traditionally available only in high-end power quality recorders. Records THD to the 255th order peak.
Real Time Phasor Analyzer - The unit monitors phase angles between the voltage and the currents.
Web Server Capability – Data from meters is viewable over the web. Data from the ModBus devices connected to the meter can also be viewed.
Expandable I/O Modules for Analysis and Control Target Applications/Industries:
Primary Monitoring of low medium and high voltage application, requiring full metering, with data logging, controls and high speed oscillography (waveform).
Remote monitoring over the web using web pages
Applications requiring Control Relays with set-point activation, Analog and digital I/Os.
Heavy power users for need of clean power - Data Centers, Microprocessor Chip Manufacturers Pulp and Paper, Oil & Gas…….
OEMs, Electrical Panel Manufacturers, Switchgear manufacturers, Motor Control manufacturers…..
