Abstract
PURPOSE: To make a protective device providing a break function with a reversibility for temperature, by a method that with a resistance value, of non-inductive winding arranged in the transformer, measured and compared, an input-output circuit switch be operated when in a time of high temperature (when becoming a high resistance).
