Combined Standard Source and Meter Reference AC DC Three Phase Testing Calibration System

It Is Composed Of Program Control Three Phase Standard Source, DC Standard Source, Three Phase Sampling Type Multifunctional Standard Meter, And Computer With Standard Table And Management Software Installed.


1 semi-automatically or manually test the basic error of a variety of power frequency meters (voltmeter,ammeter, power meter, frequency meter, power factor meter, phase meter), and test the change value cause by influence of voltage, current, waveform and power factor

2 can automatically measure the basic errors of electric transducers (voltage transducer, current transducer, power transducer, frequency transducer, power factor transducer), and the change value caused by influence of votalge, current, waveform and power factors etc

3 can generate distortion wave with 2~31 order harmonic, harmonic number, order, amplitude and phase to fundamental wave all can be program controlled

4 Power amplifier’s working frequency 40Hz~1KHz, good linearity. Current power amplifier is constant-current source, and voltage power amplifier is constant-voltage source

5 Testing by PC automatic control or manual control, capaple of data analyzing and managing

6 Auto calibrate energy meters
