TIME AND DATE CHECK: If the time and date is not being maintained by an IRIG-B signal, so in the event of the auxiliary supply failing, with a battery fitted in the relay, the time and date will be maintained. To test this, remove the auxiliary supply from the relay for approximately 30 seconds, on restoring the auxiliary supply the time and date should be correct. Result: ____________

S/S 9019 380 kV І – LOWER SLOPE Connect the test circuit as shown figure.
Current is injected into the R phase which is used as the bias current and another current is injected into the Y phase which is used as differential current. Inject a bias current of 1A in the R phase. The relay will trip and any LED associated with the R phase will operate. Slowly increase the current in the Y phase until phase Y trips . Record the phase Y current magnitude and check that it corresponds to the following equation;
Id Calculated = 0.5 * (Is1 +I bias K1)
A
Where; IS1; The Basic Diff Current Setting. K1; The Lower Percentage Bias Setting. Set; IS2 = 4 In To check more than one point at the same slope, Change the bias current value and the equation above can be used, and also for other differential settings '' Different slopes, I s1 ''. Apply the above procedure for each phase.

S/S 9019 380 kV І – LOWER SLOPE Connect the test circuit as shown figure.
Current is injected into the R phase which is used as the bias current and another current is injected into the Y phase which is used as differential current. Inject a bias current of 1A in the R phase. The relay will trip and any LED associated with the R phase will operate. Slowly increase the current in the Y phase until phase Y trips . Record the phase Y current magnitude and check that it corresponds to the following equation;
Id Calculated = 0.5 * (Is1 +I bias K1)
A
Where; IS1; The Basic Diff Current Setting. K1; The Lower Percentage Bias Setting. Set; IS2 = 4 In To check more than one point at the same slope, Change the bias current value and the equation above can be used, and also for other differential settings '' Different slopes, I s1 ''.
