Conventionally, relay setting has generally been determined as shown in the relay setting calculation formula column. There is. In the case of both conventional analog relays and computer-type relays, the user manually calculates the relay setting value for each relay based on a relay setting calculation formula, and performs relay setting using this relay setting value. For example, when carrying out relay setting in the case of the relay device 50S, the line impedance Z of the transmission line in the protected area of the power system to which this balanced relay is applied is
