DORELCO’s Tolosa Substation and LEYECO III’s Tunga & Alang-Alang Substations were re-energized at 2:18AM Dec 8, also through Maasin Substation. A cut phase C jumper on Structure 119 in Bagalongon, Kananga, Leyte, caused the tripping of Tunga Feeder at 7:12PM Dec 7 and the unbalanced voltage observed when the feeder was re-energized at 7:19PM. NGCP requested affected electric cooperatives not to load their feeders until the condition was corrected. Line inspection and line tests were conducted to pin-point the line fault, which was found and corrected by 3:47AM, Dec 8. These activities were delayed by strong rains in Kananga area. Tunga Feeder was normalized this morning with the transfer of DORELCO and LEYECO III loads from Maasin Substation to Ormoc Substation.
