Blown off or burn out fuses caused by short circuited loads or appliances
Loose wires joints, connections tapings to transformer, cut outs transformer, etc.
Wire cuts or cut ground wires
Burn out equipment, poles, cross arms, and others.
Electrical troubles of overhead lines:
a. Faulty or fractures line insulators due to lightning or swtching operations causing high frequency oscillations and abnormally high voltages.
b. Blown line fuses caused by trees falling across lines, occurrences, of landslides which may overturn supports, severe floods that may wash away pole foundations, storms and strong winds that often caused system troubles and may even break wires.
c. Blown transformer fuses due to overloads(fying connections, illegal connection/energization)
d. Burned poles due to fires from ground.
Vehicular accidents that topple or break electric posts cause wire down and other damage to electric facilities.
Fires & Floods
During such emergencies, ZAMSURECO-I cuts off power in the affected circuit area until it is safe for residents.
Trees & Kites
Tree branches that touch bare high-tension wires and kites and strings that get entangled with these wires also cause power interruption. Trim trees before they touch the wires. If branches are beyond normal reach, we will be glad to assist you in trimming them. Call us at 1621.
Rampant theft of electricity in an area often overloads electrical facilities. Under Republic Act 7832, electricity or line material pilferage is a serious crime which metes a penalty of up to 20 years of imprisonment. The law also makes the offender liable to pay the value of electricity pilfered plus surcharge.
Falling debris and equipment that touch electric wires in construction work near existing ZAMSURECO-I facilities is another reason. Parties responsible for such outages may be penalized.
Typhoon Winds & Lightning
Electric wires, transformers and substations hit by lightning during thunderstorms also cause power interruption. Typhoons can cause serious and widespread damage to these distribution facilities.
Maintenance and upgrading work on distribution facilities (poles, wires, transformers) is done regularly. During these times, power interruption is scheduled. The schedules are published on Friday at the Maintenance Schedule page of this website.
