clamp meterTo test the high-voltage system, a type of high-voltage clamp ammeter must be used. To possess: high precision, strong stability, * * resistance and insulation protection. The accuracy of test data is also highly required while ensuring the safety of on-site measurements.
clamp meterIn the application of high-voltage systems:
1. Suitable for measuring high and low voltage systems of 60KV and below, 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. Measuring the current of high-voltage system lines, online current measurement, as well as peak holding, data holding, storage, wireless transmission and other functions. Its clamp ammeter can easily clamp or withdraw the measured wire by pressing or pulling out 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 gauge with a minimum range of 10 microamperes.
A high-voltage large-diameter clamp ammeter is an instrument used to measure the current value of high-voltage transmission 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.
