Abstract:
An apparatus, and a method of controlling a solid state power controller (“SSPC”) selectively allows a current through a solid state power control switch in response to the current in a plurality of SSPCS exceeding at least one threshold. A microprocessor module collects power surge data from a plurality of groups of SSPCs, and determines if the amount of power surge data within a group of SSPCs is sufficient to constitute a lightning threat. If the microprocessor module determines a lightning threat is present, the microprocessor module sends a command to certain SSPCs in the afflicted group to lockout an instantaneous trip protection for the duration of the lightning threat, allowing the power surge to pass from the SSPCs to a load or plurality of loads, leaving the SSPCs undamaged.
