Three Phase Meter Test Bench

1. Error test, start test, creep test, standard deviation test..etc

2. Measurement of volts, current, p.f., power, frequency, phase angle, harmonic..etc..

3. Power Source (PS): output 0-360V/phase & 1mA-120A/phase, or depend on client requirement

4. Standard Reference Meter (SRM): accuracy class (0.02, 0.05 or 0.1) is optional

5. Can be independent set & output of each phase voltage & current

6. Can set phase angle independently

7. Meter Rack: positions (3, 6, 10, 12, 20, 24,40..) are optional

8. Automatic control by PC software

9. Manual control by touch screen
