Summarize

FYLTH-PS Potable Single-phase kwh Meter Test Bench is a semi-automatic device desighed according to the national standards and regulations. This device is composed of single-phase power supply and wide-range standard power watt-hour meter. It is of high accuracy , wide range and light weight, and it can be easily operated. It can be used not only in the testing room, but on-site, and can test or check the single-phase electronic or inductive watt-hour meter under 1.0.

Main technical parameters

1.       Input voltage :220V  45~65Hz

2.       Switch of the selection of current measuring range:

Divided into 11 stalls, each stall difference between output current is 1 time, we can choose a suitable stall by tested meter. (propose to use the sixth stall which is 5A)

3.       Output current waveform distortion:<2%

4.       Accuracy level of monitoring voltage , current meter (digital diaplayed):1.0(or0.5)

5.       Accuracy of test bench :0.2,0.3(the level of standard meter :0.1 ,0.2)

The testing total error wonnot  exceed the national standard JJG597-89, which  is shown in attached table 1

6.       Stability of output voltage , current and power <0.5%(PF=1.3min)(equipped with high-accuracy voltage-stabilized source)
