High voltage measurement system for power equipment handover test

　　The high voltage measurement system is composed of high voltage divider, wave recorder, signal cable and related meters.

　　There are three types of high-pressure voltage divider, which are selected according to different test requirements:

　　High voltage resistance voltage divider - DC high voltage test;

　　High voltage capacitor voltage divider - AC high voltage test;

　　High voltage resistance capacitance voltage divider -- shock wave test;

　　High voltage divider is not only a conventional equipment for high voltage test, but also an indispensable test equipment for high voltage test. The special divider is used together with the test device. If the parameters of the divider are appropriate, it can also be used as a general equipment.

　　Induction voltage withstand test power supply device

　　The induction voltage withstand test power supply device is a special equipment for the test of power transformer, iron core reactor and electromagnetic voltage transformer.

　　The power supply device for induction voltage withstand test can be:

　　Frequency doubling power supply and supporting excitation transformer;

　　Frequency modulation power supply and supporting excitation transformer;

　　Induction voltage withstand device of triple frequency transformer group;

　　Power frequency generator;

　　Frequency conversion generator and other equipment.

　　Appropriate test power supply shall be selected for induction voltage withstand test of power transformer, and the capacity and margin of test power supply shall be fully considered to meet the test requirements.
