C233 Three Phase Power Calibrator

The C233 Series Power Calibrators are used for adjusting, checking and verification of measuring instruments used in power engineering: active and reactive power meters, phase meters, frequency meters, ammeters, voltmeters, transducers of these quantities, monitoring systems and frequency, voltage and current relays in single and three phase symmetrical and asymmetrical configurations for symmetrical and asymmetrical loads.

The C233 Calibrator is three phase source of alternating current and voltage. Enables generating alternating voltages up to 420V in four subranges 57-110-220-380V, alternating currents up to 20A (100A) in three (four) subranges 1-5-20-100A, frequency in range 45.00…70.00Hz and phase shift in range -90.0…0.00…+90.0°.

Voltage and current output signals are set by multi-turn potentiometers and are simultaneously indicated on 4.5 digit LED displays. Frequency and phase shift are also set by multi-turn potentiometers and are displayed on 4 digit LED displays too.

Instruments to be calibrated can safely be connected to the outputs without changing the set values since the calibrator can be switched to “standby” mode to isolate the output terminals.

Series C233 Calibrators has been built in three standard 19'' aluminium cases and consists of one calibrator basic configuration (phase L1) and two calibrators in special configuration (phase L2 and phase L3).
