4.1 - CHECKS TO BE PERFORMED BY THE BARE EYE
(Checks to be Performed While the Main
Busbar is De-energized)
4.2 - MECHANICAL CHECKS (Checks to be Made in This Section Should Be Performed While
the Main Busbar is De-energized.)
IMPORTANT WARNING:
Never connect the MV cables connected to the output terminal in a way that will
force the output terminals to pull down.
4 - COMMISSIONING
If a cubicle array will be formed by arranging various types of MMMH cubicles side by side and the commissioning
wil be performed for the first time, it is recommended by our company to apply the following procedure:
1. Check whether the connections of the cubicles’ main busbar are connected along with the disconnector or the
load break switch or not and tighten the loose bolts and nuts if required. While checking the connectivity, be
careful from damaging the bushings of the disconnector or the load break switch. Never step or walk on the
busbar, disconnector or the load breaker switch
1. Perform “Commissioning”, “De-commissioning” and the “Accessibility to Cable Connection Compartment” for
each cubicle in accordance with the operating instructions sticked on them. During that, check the mechanical
interlocks are operating properly and no problems are occured.
2. Please contact EVA ELEKTROMEKANİK on (0090 312 811 2727) if any problem is encountered during the above
points.
2. Check if there is any unusual object inside the cubicle and take it out.
3.
Check that there is at least 100 mm gap between the cubicles’ back and the building’s wall and that there is no
objects in between.
4.
Check whether the side cover plates used against the internal arc are fixed, if not fix them so.
5. If there is a battery rectifier group in the facility, ensure that is connected to a 220 / 230 VAC source.
6.
Ensure the grounding system of the cubicles by checking the grounding busbars of the cubicles’ array
which must be properly and tightly connected to each other. Also, ensure the cubicles’ grounding system by
checking the earthing busbar of the first or the last cubicle which must be connected to the external earthing
system by an earthing conductor.
7. Check the connections of the LV cabinet.
4.3 - SUPPLYING VOLTAGE TO THE MAIN BUSBAR AND REQUIRED CHECKS
4.4- OPERATING THE CABLE CONNECTION CUBICLE
4.5- SHUTTING DOWN THE CABLE CONNECTION CUBICLE
1. By Switching off the switching elements of the incoming cubicle, energize the main busbar and wait for 90 to
120 minutes.
2. Ensure that the voltage indicators lamps of the incoming cubicle are off.
3. If no problems were observed then energize the cubicles one by one as stated below.
4.
After energizing the cubicle’s array, check whether if there is unusual noise or not.
1. If the Cable Connection Compartment door of the Cable Connection Cubicle is Open, CLOSE it.
2. Switch off the output feeder feeding the cubicle.
3. Ensure the voltage indicator lamps are on.
1. Switch on the output feeder feeding the cubicle.
2. Ensure the voltage indicator lamps are off.
