Abstract

PURPOSE: To prevent the overvoltage applied to a thyristor by paying attention to the fact that the overvoltage generated at the cut off of the AC section circuit breaker becomes the inter-terminal voltage of the AC section surge absorber, detecting this voltage, and equivalently short-circuiting the inter-terminal of the AC section surge absorber.
