Abstract
A protection system in which a shunt protection device at the interface terminals is optically triggered by sensor components within the circuit. This permits a variety of appropriate overvoltage detection thresholds to be defined at different nodes within the circuit. Preferably the shunt protection device is combined with one or more series protection devices which interrupt overcurrent.
