6.0 Maintenance
Warning!
Only qualified personnel should do maintenance tasks!
Note
: De-energize the CCR whenever disconnecting and connecting plug in electronic cards. With circuit selector all circuits are
connected in series and short circuited. Circuits are not disconnected from the high voltage output. Selection of any combination
of circuits is made within the circuit selector by removing the shorts. Always check for high voltage before any work with the
AFL-circuit.
6.1 Content of Maintenance Work
The CCRs are designed using proven technology to reduce the maintenance requirements to minimum.
The maintenance tasks are securing the optimal performance of the constant current regulator and minimizing service
interruptions.
Preventive maintenance program is recommended to be applied whenever possible. It can be divided in the following
categories:
Type of check Action Man.ref CT ref *
Visual Remove dust and dirt if necessary
Check wiring, especially earth wires.
Check if loosened terminal screws.
Check if any damaged or loosened components.
Functional Run all current steps.
Check remote controls and indications.
Check protections (at least open circuit)
2.5 Protective functions CT-8000-LC
CT-8000-RC
CT-8000-PR
Calibration Output current calibration check. 2.4.1 Output current I2 and voltage U2 calibration CT-8000-CA
Other calibration check, if desired. 2.4.x
* Appendix I – Commissioning test report form
The front doors can be only opened when the main switch is in off-position. When the door is opened the main switch can be
switched on with the small handle on the switch if test runs are needed to be performed. The doors can be also removed
temporarily by lifting them from their hinges and disconnecting the earth connections.
Note:
Remember to reconnect earth wires when reinstalling the doors and covers of the CCR.
6.2 Standard of Maintenance Work
Personnel responsible of the maintenance tasks should be familiar with standards IEC61821, FAA AC150-5340-26 and the
national and local safety regulations and requirements.
6.3 Cycle of Maintenance Work
Recommended maintenance period for CCR’s installed in substation environment where the CCR is not targeted by excessive
dirt or humidity is one year.
In environments where dust or dirt is very severe, cleaning and verification of air circulation inside the CCR can require shorter
maintenance periods.
