3. Wireless high voltage current sensor ratio tester model: zrx-2585
Product characteristics
Measurements: currents, mutations, deviations, angle differences, differences, polarity, leakage online testing monitoring; current size, variation compared to online testing monitoring on both sides of the transformer; high-altitude currents, leakage testing; one or two circuit nuclei, sequence determination functions。
The wireless high-voltage ratio tester breaks through the traditional structure and consists of high-pressure detectors, low-voltage current pliers, mainframes, high-pressure insulation poles, surveillance software, etc. The wireless transmission test data can penetrate multi-storey floor barriers with a direct transmission distance of up to 300 metres. If insulation poles are not used, they can also be used as precise low-pressure plating and leaking meters and can accurately detect currents or leaks of 0. 01 ma - 1000a。
