PURPOSE: To improve a connecting operability of a relay testing unit to a power protection relay unit to be tested.
CONSTITUTION: A testing terminal 25 of a testing base 24 is connected to a connecting terminal 21 of a relay testing unit 20 via a connector cable 23. The base 24 forms an insertion unit 28 for detachably inserting an edge in which a plurality of terminals 27 to be connected of a power protection relay unit 26 to be tested are arranged in parallel. A plurality of testing terminals 25 to be connected to the terminals 27 of the unit 26 are arranged in the unit 28. Accordingly, the unit 26 can be easily connected to the unit 20 in a short time merely by inserting the unit 26 to the unit 28 of the base 24 connected to the unit 20 via the cable 23. There is no erroneous connection. Reliability of the connection is improved.
