Zamcelco blames NGCP for voltage fluctuation Print

The Zamboanga City Electric Cooperative (Zamcelco) has attributed incidents of voltage fluctuation to a problem in the system of the National Grid Corporation of the Philippines (NGCP).

“There was low voltage in the system so they advised us to drop load,” said Ancheta during a radio interview over E-media’s Conversa yesterday.

He explained that Zamcelco’s own system will bog down if they fail to implement the NGCP’s instruction.

The fluctuation is caused by the delivery of low voltage by NGCP.

Instead of delivering 69kv, they (NGCP) deliver 64kv or lower, thus causing a trip-off in sub-stations, Ancheta explained.

The problem was described by Ancheta as “transient,” saying that it only happens in certain instances.

On May 24, a drop in voltage recorded just minutes apart caused a trip off of the Camanchile substation which in turn affected several feeders.

Last Monday, Zamcelco issued an advisory informing consumers of a voltage fluctuation eight minutes apart starting at 1:20pm.

The problem, which reportedly originated from the transmission side of the NGCP caused the trip off of two power transformers at the Camanchile substation serving the areas of Sta. Catalina, Rio-Hondo, Veterans Avenue, Governor Alvarez, Nuñez and ACLEM.

In a previous interview, Ancheta said that two major power outages during the weekend were for preventive maintenance of NGCP lines, an objective of which is to solve the voltage fluctuations.

The problem however persisted just hours after power resumed last Sunday, based on complaints aired on social media.  (LAJ)
