Commissioning Tests
If the relay is wired through a test block it is recommended that all secondary injection tests
should be carried out using this block.
Ensure that the main system current transformers are shorted before isolating the relay from the
current transformers in preparation for secondary injection tests.
DANGER
DO NOT OPEN CIRCUIT THE SECONDAY CIRCUIT OF A CURRENT TRANSFORMER SINCE
THE HIGH VOLTAGE PRODUCED MAY BE LETHAL AND COULD DAMAGE INSULATION.
It is assumed that the initial preliminary checks have been carried out.
Relay CT shorting switches
With the relay removed from its case, check electrically that the CT shorting switch is closed.
Primary injection testings
It is essential that primary injection testing is carried out to prove the correct polarity of current
transformers.
Before commencing any primary injection testing it is essential to ensure that the circuit is dead,
isolated from the remainder of the system and that only those earth connections associated with
the primary test equipment are in position.
Decommissioning & Disposal
Decommissioning: The auxiliary supply circuit in the relay may include capacitors across the
supply or to earth. To avoid electric shock or energy hazards, after
completely isolating the supplies to the relay (both poles of any dc supply),
the capacitors should be safely discharged via the external terminals prior to
decommissioning.
Disposal:
It is recommended that incineration and disposal to water courses is
avoided. The product should be disposed of in a safe manner.
