ツク装置。 A protection calculation unit has a software configuration that has a large number of relay elements and performs protection calculations for each relay element, and a large number of relay elements that are turned on and off through protection output circuits based on the protection calculation results of each relay element. In a digital protective relay device equipped with an output relay, a function check item of the protective output circuit and the output relay is deciphered from an item selection switch and a selection operation of the switch configured by software in the protection calculation section. An item selection element, a function check start switch, and a logic configured in software in the protection calculation unit, and which causes the output of the item selection element to be a function check input to the corresponding protection output circuit by operation of the start switch. 1. A function check device for a digital protective relay device, characterized by comprising a product element.
