with Digital Signal Analysis

Arbiter Systems®, Inc. Model 933A Portable Power SentinelTM is the most accurate and most affordable portable power quality meter in the industry. The proprietary EnergyDSATM Digital Signal Analysis algorithms allow the user to measure or record harmonics, flicker (per IEC 61000-4-15, PST and Instantaneous), K-factor and interruptions. The data logging capabilities of the Portable Power SentinelTM allow the user to specify the data to log as well as when to log the data, continuously or when user specified thresholds are exceeded. The high accuracy, portability and data logging capabilities make the Portable Power SentinelTM the perfect field analyzer for the power quality engineer.


935 A Current Source:

The Arbiter Systems®, Inc. Model 935A Current Source is designed to drive high currents, up to 1000 amps rms, through low impedance loads. Output current is produced at the input line frequency through a toroidal current transformer. The input line level is selectable from 100, 120, 200, 220, and 240 volts rms. An output range selector switch and variable transformer allow easy setting of the output current within the attainable range.

The Model 935A is an ideal source for testing instrument current transformers. Use the Model 935A Current Source in conjunction with the Model 931A Power System Analyzer and the Model 936A Reference Current Transformer to accurately measure the ratio and phase angle errors on a wide variety of current transformers.

936A Reference Current Transformer:

The Arbiter Systems®, Inc. Model 936A Reference Current Transformer provides laboratory grade accuracy in a small, portable, ruggedized case, making it ideal for field use. Multiple ratios of 1200:5, 1000:5, 800:5, 600:5 are selectable via a front panel switch. The guaranteed accuracy over the full input range and operating conditions is 0.02% ratio and 0.01° phase (traceable to NIST), ideal for calibrating other current transformers.

The Model 936A uses an active transformer to achieve the high accuracy needed for a primary reference. This design incorporates a dual core toroid with an amplifier aided second stage. The active circuitry reduces the sense transformer core flux to zero and produces an accurate output current independent of burden. The Model 936A was designed primarily for use with the Model 935A Current Source and the Model 931A Power System Analyzer to calibrate current transformers used with the Model 1133A Power Sentinel. The Model 936A's multiple ratio selections allow other current transformers to be tested and calibrated across their entire operating range.
