ABSTRACT:
A high voltage system with self-test circuitry which senses the amount of current in a high voltage line and communicates this information by means of fiber optics to control electronics which in turn communicate said information to actuator means which compensate for excessive amounts of current or notify the operator of a fault. Also the system provides a continuous and automatic self test of the communication lines by use of a clocked parity checking system.
