Abstract
An apparatus for testing a thyristor valve includes: a current source circuit that provides an electric current when a thyristor valve as a test target is turned on; a voltage source circuit that provides a reverse voltage or a forward voltage when the thyristor valve is turned off; and a first auxiliary valve provided between a connection point between the thyristor valve and the voltage source circuit and the current source circuit, and that insulates the current source circuit from the voltage source circuit to protect the current source circuit from a high voltage of the voltage source circuit.
