NGCP warns vs safety line clearance breach

0

THE National Grid Corporation of the Philippines (NGCP) has warned construction equipment operators on the dangers of working near the transmission lines and breaching right-of-way clearance.

It cited an incident on May 6, 2016 when a crane, operating in violation of NGCP’s right-of-way safety clearances, caused a “flashover” at the Quezon-Mexico 230-kiloVolt (kV) transmission line, damaging the line conductor and concrete scaffolding in the construction site near the line.

A similar crane breach occurred on June 1 at the San Jose-Hermosa 230-kV line that dented a generator set and damaged construction equipment.

The NGCP said that even minor obstructions could cause line faults and endanger the entire grid. An incident at Doña Imelda-Paco 230-kV line last April 26 where a strand of wire from a nearby building construction fell into the line conductor caused a power outage.

The increasing incidence of safety breaches by construction companies alarms the NGCP as it risks the stability of power transmission delivery.
