ABSTRACT:
In a multi-conductor electrical assembly, each conductor is connected to a first common electrical plane via first unidirectional current devices and each conductor is further connected to a second common electrical plane via second unidirectional current devices having an opposite sense to the first unidirectional current devices. The assembly includes first and second energy-dissipating devices connected between ground and respective ones of the electrical planes such that an excessive positive or negative voltage excursion on any one of the conductors is conducted via a respective one of the first or second unidirectional current devices to the first or second plane and to ground via the energy-dissipating devices.
