Abstract

For the dielectric tests of ±800 kV thyristor valves

the test of MVU is very difficult to perform due to the large size test circuit and high test voltage etc..By using equivalent simulation load to replace parts of thyristor valves

the test techniques is studied for the MVU of ±800 kV thyristor valves

including DC test

lightning impulse test and switching impulse test.The results show that such method is practicable.
