MORE Power completes LaPaz substation repairs

MORE Electric and Power Corp. has completed the preventive maintenance works on the LaPaz substation in Iloilo City on Sunday.

In a statement, MORE Power said it started the maintenance works at 4:05 am and finished by around 4:37 pm.

The works included corrective and preventive maintenance on the 50 megavolt-ampere (MVA) power transformer and the On Load Top Changer Tank after Dissolve Gas Analysis on the facility indicated high levels of gases, which is a sign of corrosion and deterioration due to lack of maintenance works.

The maintenance works also included:

-degassing and filtering of oil in the main tank of the power transformer;

-assessment of the power transformer winding;

-testing of the 69-kilovolt (kV) and 13.8 kV transformers (current and potential);

-testing of the functionality of seven overcurrent protection relays and circuit breakers;

-installation of check meters in six feeders; and

– testing of Direct Current (DC) station batteries.

The distribution utility also replaced rotting electric poles and cross-arms in distribution and feeder lines in LaPaz.

MORE Power said the repair and maintenance are necessary to extend the life of the substation and prevent breakdowns which could lead to massive and prolonged brownouts.

“We now have a benchmark on the conditions of these facilities which will become the basis for future Preventive Maintenance Services and prevent bigger problems and long power outages. We thank our consumers for their understanding and sacrifices for the inconvenience this has caused them,” it added.
