Clamp-on ammeters in high voltage systems
Clamp ammeter test high-voltage system, must be a special high-voltage clamp ammeter. To have: high precision, strong stability performance, super anti-interference ability and insulation protection protection. In the case of ensuring on-site measurement, the accuracy of the test data is also a high demand.
Clamp-on ammeter in the application of high-voltage systems:
1, applicable to 60KV and the following high and low voltage system measurement, testing high voltage using protective insulating rod sets of detection; for 600V or less low voltage system, you can use the high voltage clamp meter to directly test the line AC current, leakage current is equivalent to a high-precision low-voltage ammeter.
2, measurement of high-voltage system line current measurement, online current measurement, but also has a peak hold, data retention, storage, wireless transmission and other functions, and its special clamp ammeter by pressing or pulling back the insulating rod can be convenient to clamp or evacuation of the measured wire.
3, can be used as high and low voltage current transformer ratio tester, zinc oxide lightning arrester tester. High precision clamp meter, the minimum range of 10 microamps.
High-voltage clamp-on ammeter is an indispensable instrument for measuring the current value of high-voltage lines, so it is necessary to maintain the instrument regularly. And test high-voltage personnel must be in accordance with the operating procedures and obtain the relevant national high-voltage operating certification to carry out on-site testing!
