Summary:PROBLEM TO BE SOLVED: To provide a grounding resistance measurement system capable of appropriately measuring a grounding resistance even when a prescribed value of the grounding resistance differs according a distribution system, a region, and the like.SOLUTION: A grounding resistance measurement system comprises: a high-voltage system database 21a; an equipment ledger database 31a; a grounding resistance prescribed value database 43a; a grounding resistance measurement device which is disposed in a high-voltage system and measures a grounding resistance value; a grounding resistance prescribed value acquisition task 46 which acquires a grounding resistance prescribed value of electric equipment according to a location of the high-voltage system in which the electric equipment is disposed on the basis of the high-voltage system database 21a, the equipment ledger database 31a, and the grounding resistance prescribed value database 43a; and a grounding resistance acceptability determination task 48 which determines whether the grounding resistance value satisfies the grounding resistance prescribed value on the basis of the grounding resistance prescribed value acquired by the grounding resistance prescribed value acquisition task 46 and the grounding resistance value measured by the grounding resistance measurement device. 【課題】配電系統や地域などに応じて接地抵抗の規定値が異なる場合でも適切に接地抵抗測定することが可能な接地抵抗測定システムを提供する。【解決手段】高圧系統データベース21aと、設備台帳データベース31aと、接地抵抗規定値データベース43aと、高圧系統に配設され、接地抵抗値を測定する接地抵抗測定装置と、高圧系統データベース21aと、設備台帳データベース31aと、接地抵抗規定値データベース43aとに基づいて、電気設備の接地抵抗規定値を、電気設備が配設された高圧系統の位置に応じて取得する接地抵抗規定値取得タスク46と、接地抵抗規定値取得タスク46で取得した接地抵抗規定値と、接地抵抗測定装置で測定した接地抵抗値に基づいて、接地抵抗値が、接地抵抗規定値を満たしているか否かを判定する接地抵抗良否判定タスク48と、を備える。【選択図】図2
