35. 1 1 Overview Testing Testing amp Troubleshooting Relay testing is typically divided into two categories Relay tests are performed when the relay is installed or commissioned and periodically once the relay is in service This chapter provides information on both types of testing for the CET 5 relay Because the CET 5 is equipped with extensive self tests traditional periodic test procedures can be eliminated or reduced Ifa problem occurs during either commissioning or periodic tests this chapter provides a guide to isolating and correcting the problem Commissioning Tests Introduction Each CET 5 is fully calibrated and functionally tested prior to shipment This helps to ensure that you receive a relay that operates correctly and accurately Commissioning tests must verify that the relay is properly connected to the motor and all auxiliary equipment Verify control signal inputs and outputs Use an AC connection check to verify that the relay current and voltage inputs are of the proper magnitude and phase rotation Brief functional tests ensure that the relay settings are correct It is not necessary to test every element timer and function in these tests The following procedure is a guideline to help you enter settings into the CET 5 and to verify that it is properly connected Modify the procedure as necessary to conform to your standard practices Use this procedure at initial relay installation you
