Energy and Power Quality Meters
Schneider Electric
Used to monitor electric energy provider networks, service entrances and substations, ION8600 meters are ideal for independent power producers and cogeneration applications that need to accurately measure energy bi-directionally in both generation and stand-by modes. These meters give utilities the tools to manage complex energy supply contracts that include commitments to power quality. Integrate them with our StruxureWare Power Monitoring (ION Enterprise™) operations software or other energy management and SCADA systems through multiple communication channels and protocols, including MV-90, Modbus and DNP.
  • Tariff metering, Volts, Amps, KW, Hz, cosphi, KWh and time-of-use metering.
  • Waveform capture, transient capture, dip/swell monitoring, harmonics measurement (up to 63rd), symmetrical components, percent uptime.
  • Power quality compliance monitoring (IEEE 519/1159, EN50160, IEC 61000-4-7/4-15).
  • Sequence-of-events, coincident minimum/maximum, historical trends, and high-speed snapshot recording, 1 ms resolution timestamping, GPS time synchronisation.
  • Communication ports: Ethernet, modem, RS-232/485, RS-485, front panel optical.
Schneider Electric
Used at key distribution points and sensitive loads, ION7550 and ION7650 meters offer unmatched functionality including advanced power quality analysis coupled with revenue accuracy, multiple communications options, web compatibility, and control capabilities. Customise metering or analysis functions at your work station, without hard wiring. Just link drag-and-drop icons or select default settings. Integrate the meters with PowerLogic™  ION Enterprise™ software or share data with SCADA systems via multiple communication channels and protocols.
The ION7650: revenue-class power and energy metering, event and min/max logging, historical logging (up to 800 channels), expandable memory, sag/swell monitoring, harmonics measurement, waveform capture at 1024 samples/cycle, disturbance detection, setpoints, digital and analogue I/O, and Internet-enabled multi-port communications.
Main characteristic:
  • Volts, Amps, KW, Hz, cosphi, KWh and time-of-use metering.
  • Instrument transformer correction, transformer/line loss compensation.
  • Total harmonic distortion (THD) and invidiual harmonics (THDi).
  • Protocols: Modbus RTU slave/master, Modbus TCP, DNP 3.0, MV-90, IEC 61850.
  • Ethernet and modem gateways to 31 devices on RS-485 port.
  • On-board web server, email for alarms and data, FTP server.
General Electric
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.
The PQM II's features are:
  • A true RMS meter, 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 with 0.2% accuracy for voltage and currents.
  • Panel mount with display, offers an easy local interface. Standard models have RS485 communications for programming and monitoring.
  • Any of the assignable outputs may be used to trigger an alarm for specific applications. Simple alarm messages provide easy notification.
  • 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.
  • Power quality measurement: data logger (trending), harmonic analysis, voltage disturbance recorder (VDR), waveform capture, event recorders up to 150 and trace memory of data on all voltage and current inputs based on overvoltage, undervoltage, overcurrent or switch input state change.
The Allen-Bradley PowerMonitor 5000 leverages new technology and capabilities to capture comprehensive power quality data about your energy network.
The PowerMonitor 5000's features are:
  • Scalable Power Quality platform product monitors four voltage and four current channels for each electrical cycle.
  • Provides 1024 samples across eight channels every cycle.
  • Revenue Metering accuracy 0.2%
  • Voltage, current, neutral and earth current, power, frequency, power factor, demand, energy, and time-of-use metering.
  • Power quality measurement: harmonic analysis up to the 127th, waveform capture sub-cycle transients detection, internal web page for the meter simplifies configuration and allows you to view real-time data.
  • Virtual wiring correction capability can correct miswiring during commissioning, reducing the need to power down for correction.
  • Configurable alarms for up to 10 events can help prevent issues or equipment damage.
  • Four inputs for WAGES (water, air, gas, electricity, steam) data collection.
  • Four outputs for connection to SCADA or control systems.
  • Native EtherNet/IP™ communication port included.
  • Option for a second communication port.
  • System event snapshot capability.
