ク装置。 A protection calculation unit has a software configuration that has a relay element consisting of a large number of calculation elements and an output delay timer, and performs protection calculation for each relay element, and is driven on and off by the output of each of the timers. In a digital protective relay device equipped with a large number of output relays, software is configured in the relay element function check item selection switch, function check start switch, and protection calculation section. and an item selection element that decodes and stores the function check item from the selection operation of the start switch, and outputs the output of the calculation element of the corresponding item as a function check signal by operation of the start switch. Function check device for protective relay equipment.
