Three Phase kWh Meter Test Bench - CL3000

Three Phase kWh Meter Test Bench - CL3000

A) Able to calibrate the electronic and inductive watt-hour meter, meter types cover single/three phase, multifunction, multi-rate and prepayment.


B) Can perform automatic measuring like shunting, starting, basic errors, standard deviation and etc.


C) Can test the error caused by voltage, current, harmonic, reverse phase and voltage unbalance.


D) Can check the same type meters with different constant.


E) GPS system is applied to verify the meter clock.


F) Available to print all kinds of test reports with the standard forms.


G) The software supports bar code input, error curve, error threshold, verification plans, weekly test plan, management authority set and user system.


H) Can test voltage/current of each phase, phase/phase difference, active/reactive/apparent power of each phase, total active/reactive/apparent power, total power factor, frequency etc.


I) Can display the real-time vector chart and waveform of voltage and current.


J) Can set 2nd to 21st harmonic of voltage and current, measuring the waveform distortion and harmonic content, can display harmonic chart.


K) Automatically test the symmetry of 3-phase voltage & current and the max. value of three-phase difference.


L) Provided standard impulse output and the impulse constant can be set automatically or manually.


M) Equipped with RS485 & RS232 communication ports.
