Abstract: An apparatus for monitoring a rectifier leg which forms a part of a system that is being supplied with electrical power from an external circuit. The rectifier leg has at least first and second series connected rectifier cells. The monitor apparatus includes a source of control power for supplying electrical power to the monitor apparatus as well as to the rectifier leg. The monitor apparatus provides an indication of open and short circuit failure of the rectifier cells while they are in use in the system and being supplied with electrical power from the external circuit or while they are being supplied with electrical power solely by external circuit or while they are being supplied with electrical power solely by the source of control power of the monitor apparatus.
