Causes of Power Interruptions
Man-Made Accidents
Accident and sometimes human carelessness often cause power interruptions or brownouts. Vehicles hitting an electric wires and cause prolonged brownouts until the fallen post is replaced and the broken wires are reconnected.
Trees falling on wires, outdoor machines and construction equipment hitting and cutting off electric wires disrupt electric service.
Thunderstorms and Typhoons
When lightning hits electric wires, transformers or substation, widespread power interruptions will ensue. Typhoons can cause substantial damage to distribution facilities, resulting in extensive and prolonged service of interruptions.
Fires and Floods
These emergency situations make it necessary for COTELCO to shut off power temporarily in the affected area for public safety.
Lack of Power Supply
Like any complex machine, the generating stations of the National Power Corporation which supply electricity to the Mindanao Grid have to be stop occasionally for repairs, adjustments or annual maintenance.
Whenever the available supply is less than the combined customer dem and. COTELCO has to resort to rotating service interruptions or brownouts, as they are commonly known, to prevent the remaining running units from getting overloaded a situation that could develop into a total system shutdown.
Brownouts tends to happen when customer dem and is at its highest.
Prearranged Interruptions
Electric service is cut off at designated hours, usually on weekends so that COTELCO crews can do maintenance work and upgrade distribution facilities like high tension wires, poles, transformer, tec. This is necessary to improve service reliability in the distribution system.
Trees and Vegetation
Intermittent interruptions are often caused by branches of trees, coconut fronds or bamboo plants momentarily touching bare high tension wires as they are blown by strong winds.
At worst, they can cause lines to burn and fall on the ground.
