To alleviate brownout incidents in Zamboanga del Sur, system operator National Grid Corporation of the Philippines (NGCP) has deployed its linemen to undertake ‘hotline’ or live line maintenance work in the area.
NGCP said the company’s most recent focus had been on the transmission firm’s 69-kilovolt Pagadian-San Miguel line “to replace old cross-arm and insulator strings of transmission structures.”
The facility was located at Tikwad, Dumalinao in Zamboanga del Sur.
NGCP said a hotline or live line repair work is a proven technology in the electric transmission industry.
By far, such activity allows “the safe repair of high voltage lines without shutting them down….and by doing so, electricity consumers do not experience service interruptions while NGCP works on the energized lines.”
‘Hot spots’ would refer to the “abnormal heating of components or parts of transmission line due to loose connections between points where electricity flows.”
