Patent attributes
A power quality monitor (PQM) module includes a solid-state semi-conductor switch having a voltage input, two signal inputs and two voltage outputs. A voltage input line is electrically connected to the voltage input. A PQM signal input line is operatively connected to at least one of the two signal inputs. A voltage output line is electrically connected to one of the two voltage outputs to provide power to a load. A method of controlling a GCB includes opening a solid-state semi-conductor switch when a PQM signal is powered at a first logic voltage. The method includes closing the solid-state semi-conductor switch when a PQM signal is powered at a second logic voltage lower than the first logic voltage to allow a voltage from a GCU to go to the GCB.
