Completing The Test - ABB RET670 Commissioning Manual

1MRK 504 154-UUS B
1. Inject the polarizing voltage 3V0 to about 90% of the setting (
2. Activate the CRL binary input.
3. Increase the injected voltage to about 110% of the setting (
4. Activate the CRL binary input.
5. Check that the ECHO, CS and TRWEI appear on the corresponding binary output or on the
local HMI.
6. Reset the CRL binary input.
7. Activate the BLOCK binary input.
8. Activate the CRL binary input.
9. Reset the CRL and BLOCK binary input.
10. Inject the polarizing voltage 3V0 to about 110% of the setting (
angle between the voltage and current to (180°-
voltage.
11. Inject current in one phase to about 110% of the set trip current (
12. Activate the CRL binary input.
13. Abruptly reverse the current to 65° lagging the voltage to trip the forward directional
element.
14. Switch the current off and check that the ECHO, CS and TRWEI appear on the corresponding
binary output during 200ms after resetting the directional element. If EF4PTOC also trips in
forward direction, CS should be obtained.
15. Switch the polarizing voltage off and reset the CRL binary input.
