Acceptance Tests

3.8 Signal and Trip Relay Test

This test checks the operation of a subset of the signal and trip relays. Factory presets are used for this test. A three-phase current large enough to cause the emergency overcurrent protection to pick up is applied to the three phase current inputs. This fault condition causes a specific subset of the relays to close.

Test Procedure

1. Connect test equipment to the relay as indicated in Table 3-15.

Note: The frequency of the test current must be the same as the relay’s rated frequency (fN), as defined at address 7899.

2.Set the input current to zero.

3.Power on the relay. All relay contacts should be open.

4.Using the programming procedures described in “Programming the Relay,” ensure the settings for the signal relays (addresses 6201 - 6211) and the trip relays (addresses 6401 - 6405) match the default settings shown in Table 5-30. Also, ensure the settings shown in Table 3-16 are as indicated.
