4. MAINTENANCE
The reliability of the equipment is strictly related to maintenance operating performed during its own life.
The standardization of components has reduced the maintenance and the working chooke of the equipment. The
automatic P.F. Correction Equipment of "G3E" type have been designed and manufactured to reduce any maintenance
operation, but periodic checks are recommended:
Working capacitor Overpressure operating
Overpressure disconnector working
5. SPARE PARTS
Excluding the capacitors, it is easy to find most components, used to manufacture the COMAR equipments, on the
open market. If there were some components that needs return delivery to repair the P.F. Corrector, it's possible to
contact the COMAR Condensatori S.p.A. company and specify, the component part, the type and serial number of the
equipment - visible on the aluminium plate located on the right side of the P.F. Corrector. It will be careful of our
Commercial Office to send you quickly the requested components or advise where you can find them.
• Every six months check:
- There aren't loose connections (tighten all power connections)
Overpressure
-Regular operation of the regulator.
disconnector
-The discharge resistors of the capacitors aren't burnt or interrupted.
after working
-Check the current absorbed from each capacitor bank, measuring any
phase, recording the values and comparing with rated currents. In
case of variations higher than 15%, check if there are broken
capacitors and eventually replace them.
Every twelve months:
•
-Check the state of auxiliary contacts in the power contactors, to
avoid the damage to the capacitors, coming from the use of
deteriorated contactor.
Don't ever use abrasive materials on the maintenance of contacts
-Check that the overpressure disconnectors have not operated (see
fig." Overpressure disconnector" ).
