Product Features
     1. The measurement of the GIS electromagnetic voltage transformer (PT) and the capacitive voltage transformer (CVT) error (ratio difference, angular difference) can be completed by a single tester. At the same time, it can measure the capacitance division ratio, the voltage dividing capacitance, the intermediate PT ratio, the intermediate voltage, and the DC resistance of the CVT.
     2, with polarity, ratio, wiring check function.
     3, complete all tests at one time, improve work efficiency, avoid damage to the person and instrument caused by operational errors, and ensure safety.
     4. It has the characteristics of fast test speed, large amount of processing information and large storage capacity (capable of storing millions of data). The memory is 16G and can store millions of data.
     5. The tester adopts frequency conversion technology and digital processing, and has strong anti-interference ability on site.
     6. The maximum voltage of the test process does not exceed 4kV, and various protective measures are taken to ensure personal safety and equipment safety and reliability.
     7. The test process is simple to operate.
