MultiComm™ Digital Power Meter

MultiComm

The workhorses of the U.S. electric utility substation (and the Three Gorges Dam in China) for over two decades.

The MultiComm provides local indication and/or retransmission of electrical values to RTUs or PLCs in SCADA applications. The MultiComm instrument is a utility-grade, three-phase, digital power meter that connects directly to instrument transformers. Direct-connect high-voltage inputs are also available. The design and components are field-proven in the substation environment with all inputs transformer isolated. The multiple microprocessor design uses advanced digital signal processing for true RMS measurements including power. This instrument is a multifunction meter that calculates and displays Voltages, Currents, Power (real, reactive, apparent), Power Factor, Frequency, and Energy Values. Real-time Harmonics, K-Factor, Displacement Power Factor, and Demand measurements with Min/Max memory are also available.

The MultiComm instrument is an Intelligent Electronic Device (IED) and stores these measured values in internal registers for serial communication access. The 120V ac input meters, with AC power supply option, meet IEC standard 1010 and are certified by Underwriters Laboratory to meet UL and CSA standards.

Features

  • Simultaneous display of all phases
  • Push-button, in-field scaling from library of ANSI CT and PT ratios, with non-volatile memory requires no batteries for settings retention
  • Modular construction simplifies maintenance
  • One RS-232, RS-485, or Modbus plus Port
  • Transducer Outputs: 0-1mA or 4-20mA via external Analog Output Converter (AOC) device

PowerPlex Digital Transducer

PowerPlex

Real Time Synchronizing Transducer for Generator and Auto Sync Applications

PowerPlex is a utility-grade, three-phase, digital power transducer that connects directly to instrument transformers. Direct-connect high-voltage inputs are also available. The design and components are field-proven in the substation environment with all inputs transformer isolated.

The multiple microprocessor design uses advanced digital signal processing for true RMS measurements including power. This instrument is a multifunction transducer that calculates and displays Voltages, Currents, Power (real, reactive, apparent), Power Factor, Frequency, and Energy Values. Real-time Harmonics, K-Factor, Displacement Power Factor, and Demand measurements with Min/Max memory are also available.

The PowerPlex instrument is an Intelligent Electronic Device (IED) and stores these measured values in internal registers for serial communication access. The PowerPlex instrument is designed to meet IEC standard 1010 and is certified by Underwriters Laboratory to meet UL and CSA standards.

The family includes an RTS model with a separate reference voltage to calculate the phase angle to system voltage for synchronizing. The RTS high speed measurements and communications are ideally suited for gen-set applications.

Features

  • Selectable element switch
  • Transducer Outputs: 0-1mA or 4-20mA via external Analog Output Converter (AOC) device

TriPlex Three-Phase Amp and Volt Meters

TriPlex

Three Phase Amp and Volt Meters

The Bitronics TriPlex Ammeters and Voltmeters use a microprocessor to calculate true RMS quantities by sampling and digitizing the voltage or current on each phase, several times per cycle. Three-phase and single-phase models are available, all with bright, easy-to-read LED displays. It has a built-in self-diagnostic system and does not require periodic maintenance. Housed in a rugged aluminum 4-inch round case, TriPlex is certified to meet UL and CSA standards on AC powered units.

Features

  • Simultaneous display of all phases
  • Non-volatile memory requires no batteries for settings retention
  • Modular construction simplifies maintenance
  • Optional transducer outputs: 0-1mA or 4-20mA
  • Push-button, in-field scaling
  • Bitronics: A Century of Innovation

    Bitronics Measurement and Event Recording products have been used throughout the US electric utilities and internationally in traditional and cutting-edge “Smart Grid” applications. The products have been made in Bethlehem, PA, USA since 1908 and continue to be the gold standard for reliability and innovation in the electric utility substation measurement market.
