The Application of Clamp Ammeter in High Voltage System
The clamp type ammeter must be a specialized high-voltage clamp type ammeter for testing high-voltage systems. Must have: high precision, strong stability, strong anti-interference ability, and insulation protection. While ensuring on-site measurement, there is also a high requirement for the accuracy of test data.
Application of clamp ammeters in high-voltage systems:
1. Suitable for measuring high and low voltage systems up to 60KV, using a complete set of protective insulation rods for testing high voltage; For low-voltage systems below 600V, a high-voltage clamp meter can be used to directly test the AC current and leakage current of the circuit, which is equivalent to a high-precision low-voltage ammeter.
2. Measurement of high-voltage system line current measurement, online current measurement, and also has functions such as peak holding, data holding, storage, wireless transmission, etc. Its dedicated clamp shaped ammeter can conveniently clamp or withdraw the measured wire by pressing or pulling the insulation rod.
3. It can be used as a high and low voltage current transformer ratio tester and a zinc oxide lightning arrester tester. High precision clamp watch with a small range of up to 10 microamps.
The high-voltage clamp ammeter is an essential instrument for measuring the current value of high-voltage lines, so it is necessary to regularly maintain the instrument. And high-voltage testing personnel must follow the operating procedures and obtain relevant national high-voltage operation certification before conducting on-site testing
