Abstract:

To provide a ground system connection validation system which can minimize manpower required for validating condition of a ground system after a grounding work has been done and allows for selecting an electric circuit in each area and periodically making quick validation and monitoring of whether or not a grounding system is in a condition to allow proper functioning even from a site other than where grounding work was done.

A ground system connection validation system comprises: a ground system condition data generation unit 300, which generates ground system condition data and transmit the same from a transmitter section; and a consolidation unit 400, which receives the ground system condition data and transmits the same to a server, which are both provided in each electric circuit having a ground system in which a neutral line 102 of a secondary winding of a transformer 100 in the electric circuit is class-B grounded and a load side of the transformer is provided with a protective grounding conductor 107 which provides class-D grounding of equipment or the like. Ground system condition data from each electric circuit in a plurality of areas is collected by the server.
