Publication number: 20240146055Abstract: Because power receiving and distributing equipment is configured with a plurality of devices combined together, it is sometimes difficult to perform inspection operation for the inspection items separated into those set for each individual device. Therefore, in the power receiving and distributing equipment, even if an attempt is made to associate each device with an inspection result, an inspection result of a plurality of devices that are grouped cannot be associated with each device.
