Three Phase Site Energy Meter Test Instrument Type KP-P3001-A
Bofa Instrument & Equipment Co., Ltd
Three-phase site energy meter test instrument type KP-P3001-A (without voltage and current source) is an ideal instrument to test all kind three-phase energy meters accuracy below 0.2, especially for meters on site. When we want test a meter errors, the tested meter must be on load condition (or we can say the tested meter must be working). The instrument can test the errors, by comparing energy impulse from the tested meter with energy impulse from the reference meter which inside the instrument. The equipment is box structure and weight is very light, easy to carry, it is very convenience to test the installed meters on site.
