ABSTRACT:
A method and apparatus for detecting the loss of regulation in ferroresonant transformer is disclosed. The flux in the magnetic shunts is sensed by a winding. The resulting signal is differentiated. If the differentiated signal contains pulses, regulation is present, if no pulses are found the transformer is not in regulation.
