DTE-70/50Thigh voltage testing device

The high-voltage testing device DTE-70/50T (hipot tester) is designed for insulation testing of high voltage cables with rectified voltage up to 70 kV DC, as well as switchgears, arresters, insulators, dischargers, reclosers, busbars, etc., and other objects with AC voltage up to 50 kV AC. The hipot tester device features a digital kilovoltmeter and ammeter.

It boasts a single, large-screen interface and includes a built-in timer for precise measurement control. This feature allows users to set predefined testing durations, ensuring consistent and accurate results across all testing procedures.

The DTE-70/50T high voltage test system is a reliable, time-tested, portable device. Each portable set consists of two distinct modules: the control module and the high voltage module.

With the control module, users can select the operating mode (AC or DC), adjust the output level, and monitor both the voltage and leakage current from a safe distance. The control module also features an idle operation switch.

On the other hand, the high voltage module is an oil-insulated power source that supplies high voltage to the test object. It is controlled by the control module. The measurement of leakage current is useful in determining the unit under test's ability to withstand overvoltages.
