PURPOSE:To automatically test a power protection relay unit to be tested in a testing procedure responsive to a type. CONSTITUTION:An input/output switching unit 30 for assigning input/output to a power protection relay unit to be tested to a testing base 21 for connecting the relay unit to be tested. A power source switching unit 25 for switching a power source capacity is connected to the input/output switching unit. A recorder 42 for recording test data of a power protection relay unit 22 to be tested, the unit 30 and the unit 25 are controlled by a controller 40. The controller 40 has a memory 41 for storing a testing procedure responsive to the type of the unit 22, a testing power source and a wiring condition. Accordingly, a testing time is shortened, a operability is improved, and operability of a test is improved too. |
