Abstract
A protection circuit is coupled between a secondary winding of a transformer and a load. When voltage at the secondary winding of the transformer becomes abnormal, the protection circuit disconnects the power connection to the load so as to protect the load from damage. When the voltage at the secondary winding of the transformer returns normal, the protection circuit restores power to the load.
