A test comb in a relay test block is an accessory used to facilitate the connection and testing of multiple protective relays at the same time. The test comb is designed with an arrangement of pins or connectors that align with the relay terminals.

The main function of the test comb is to provide a convenient and efficient interface for connecting relays to the test block without having to make individual connections for each one. This simplifies the testing process, saves time, and minimizes connection errors.

Using the test comb, functional and calibration tests can be performed on multiple relays simultaneously by applying the appropriate test signals across the comb contacts. This allows verification of the relays’ proper operation and their ability to detect and respond to abnormal conditions in the electrical system.
