Features
1)The bench accords with the standard of "IEC 60736: 1982 testing equipment for electrical energy meters", "IEC 62053"
2)The bench can be used to test both single/three phase active energy meter and reactive energy meter (up to 0.2 class), it is also suitable for four quadrant energy meter testing.
3)The bench can do warm up test, starting test, no load test(creep test), error test(accuracy test), dial test, tests of the influence quantities(reverse phase, voltage unbalance, harmonic wave and so on) and test of repeatability of the measurements.
4)The bench is using the PWM to amplify voltage/current output, the high efficiency at >85%, and lower the heat. The PWM can check the malfunction checking, preset, alarm, and protection
5)The signal source is using the newest digital controlled sine wave technology for frequency, amplitude and phase adjust. The signal source can repeatedly add 2-21 harmonics on the first sine wave, or cause sub-harmonic wave and odd sub-harmonic wave.
6)The bench is using the HY 5303C-22 reference standard energy meter with comparison technology to offer the accuracy of energy meters
