After a series of preventive maintenance resulting in 13-hour power interruptions, Iloilo City Mayor Jerry Treñas claims that the maintenance works conducted by newcomer MORE Electric and Power Company is ‘beneficial in the long run’.
“They have to do those maintenance works or else we are in for longer and more massive unscheduled brownouts. Kung indi ta ini pag-ubrahon, mas malala ang problema naton,” states Iloilo City Mayor Jerry Treñas.
Treñas likens the case to the Iloilo City Hall needing regular maintenance on its equipment and facilities.
“Even until now, we continue to suffer from breakdowns of equipment due to lack of maintenance. Preventive maintenance is important, especially in the power industry. Eventually, we will enjoy better services if these works are completed,” continues Treñas.
According to MORE, the repairs are crucial as toxic gases have accumulated in the substations and transformers and might explode due to overloading. It may be recalled that the distribution utility recently completed its maintenance works on the Lapaz substation. The work started at 4:05am and ended 4:37pm.
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, a sign of corrosion.
