験を行う受配電設備系統保護試験装置に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power receiving and distributing equipment system protection test apparatus for testing various electric equipment of a power receiving and distributing equipment which receives power from a power system and distributes it to a load.

Description of the Related Art In a power receiving and distributing facility which receives power from a power system and distributes it to a load, whether or not various electric devices constituting the power receiving and distributing facility operate normally when newly installed or modified. Conduct a confirmation test.

低電圧電源（ＡＣ２００Ｖ又はＡＣ４００Ｖ）を印加し
て、極性を確認するやり方が一般的に行われている。For example, when performing a polarity test on a current transformer for an instrument or a transformer for an instrument, a polarity (kick) test using a dry cell or a voltage from the secondary side of the current transformer for an instrument or the transformer for an instrument is performed. An electric current is applied so that the tester individually tests. Then, finally, as a comprehensive evaluation, a method of applying a simulated three-phase low-voltage power supply (AC200V or AC400V) to the main circuit to confirm the polarity is generally performed.

動作させて停復電回路の確認をしている。In the operation test of the protective relay, a simulated accident is actually caused to test whether or not various relays operate. As a method of testing the power recovery / recovery circuit before power reception, the power recovery / recovery circuit is confirmed by simulating an undervoltage relay or the like.

法の確保が必要となる。However, in such a conventional method, since the polarity test is individually performed, the test time is increased when the power receiving and distributing equipment system becomes complicated, and the preparation and relocation of the test equipment are performed. Takes too much time. In the final confirmation of the polarity test and the operation test of the protective relay, a simulated three-phase low-voltage power supply (AC2
00V or AC400V) is applied for testing,
It is also necessary to confirm safety during the test. Further, in the confirmation test of the power recovery / recovery circuit, it is necessary to secure the test staff and the communication method at each relevant place due to the complexity and large scale of the power distribution system.

In some cases, it may cause great damage such as a power outage later. Further, when repairing nonconformity, there is a risk of returning work such as power failure again and work near the live line.
