930A Three Phase Power Analyzer - Overview

Overview
The Arbiter Systems® Inc. Model 930A Three Phase Power Analyzer is an economical alternative to the Model 931A Power System Analyzer when the DC voltage measurement transducer calibration and timer features are not required. The Model 930A has the same AC accuracy as the Model 931A with PowerDSA™ Digital Signal Analysis. Basic accuracy of 0.05% of reading and 0.05° phase, harmonic analysis, and full three-phase capability are standard.

The Model 930A includes serial communication capability. Combined with the available application software and laptop computer, is a valuable tool for use in power quality trend monitoring, as well as being a complete diagnostic tool for use in the substation and industrial power environment.

 

Arbiter Systems Model 930A Three Phase Power Analyzer

 

Features
  • High accuracy measurements.
  • PowerDSA Digital Signal Analysis.
  • Complete diagnostic functions for use in substation and industrial environments.
  • Serial Communications supports power quality trend monitoring with included software.
  • Field ready.
  • Multiple display options including three-phase displays.
  • Basic three-phase display - voltage, current, phase, frequency and power quantities on one convenient display.: Vector, voltage/current sequence and energy displays.


Model 930A measures all the basic quantities: true-rms voltage and current, frequency and phase angle, as well as power quantities such as watts (W), watthours (Wh), volt-amperes (VA), volt-ampere hours (VAh), volt-amperes reactive (VAR), volt-amperes reactive (VARh), and power factor (PF), all with 0.11% basic accuracy.

Measure harmonics and view the results graphically on the high contrast 240 x 64 graphic display. The two channels are normalized to Channel 1 fundamental phase, so you can see, for example, the relationship between current waveform distortion and voltage phase.

The 930A include a full three-phase input section, for automated three-phase measurement sequences, complete with multiple display modes:

Vector Display View voltages, currents and phase angles with their vector representation.
Voltage /Current Sequence Display ― view voltage, current and phase along with positive, negative and zero sequence values.
Energy Display ― view voltage, current, phase, frequency and energy quantities on one convenient display.

Configuration Note
Supports two main measurement channels. Channel 1 and channel 2. Any voltage or current input signal may be selected for either channel. For basic measurements (voltage, current, frequency, phase angle) any combinations of inputs may be used. For power and energy measurements (active power, apparent power, reactive power and power factor), one voltage and one current must be selected. For three-phase measurements, the input configuration is selected automatically, based on the measurement type (foe example, 3-phase 4-wire 3-element).
