Power & Energy Calibrator

Elektro Measurements offers a three phase Power and Energy Calibrator, Model OCM 133-C, from Orbit Controls AG, Switzerland. This is a bus compatible (IEEE-488, RS232 or Ethernet) three-phase calibrator for precise calibration of power and energy measuring electronic instruments, voltage and ampere meters, phase meters, integrators, power transmitters, mains analysers and many other. The main function of the calibrator is the generation of AC and DC electric power in ranges up to 280V and 30 A in each of the three phases. The accuracy of the power generation is 0.05%. For calibration of clamp ampere meters up to 1000 A an optional current coil is available. By using the cable adapter the three current outputs can be linked into one output adjustable from 0.1A to 90A. OCM133-C includes additional functions for calibration of Mains Analysers. The settings contain the selection of harmonic and inter-harmonic distortions, fluctuation of harmonic signals, modulation with periodical signals, flicker signals, ramps and many others. Extensive software permits very simple and clear selection of values, menu parameters and test steps. OCM133-C includes functions witch simplify calibration and test of three phase transducers with current or voltage signal outputs. Currents up to ±25mA and voltage up to ±12V can be measured with accuracy of 0.015%. The deviation of the measured signal is simultaneously shown at the display.
