General

AC voltage test systems with cylinder type transformers are the usual method to generate a continuously stable AC test voltage even if the load capacitance is changed. The test objects cover the transformer, cable, insulator, inductor and other equipment in the plant.

The test type can be from normal environment withstand test, to heavy corona, wet & pollution test. They are especially designed for testing all types of electrical insulation material and structures.

550kV 2A AC Test Transformer

Application

Insulators in dry, wet or polluted conditions Medium and high voltage Switch gear Instrument transformer, GIS, VT, CT Circuit breaker

Power and distribution transformers Power XLPE cables

Bushings

Reactors, Capacitors Electrical panel

AC Voltage Test Systems are not only used for these asks in industry, but also for research, development and students training.

Advantages and Features

1)Compact design requires the minimum space;

2)Over voltage protection device;

3)Low PD noise level to enable sensitive PD measurement at the test object;

4)Emergency button stop at the control desk;

5)High flexibility for connecting the HV lead.

(6)Large range of application and low acoustic noise level (approx. 65 to 75 dB)

(7)Sophisticated protection features for optimal test object & personnel protection


Available Options
