This advice was highlighted by a government online platform, which also provided video instructions on how to safely manage electricity in such situations.
Unplug all major appliances from outlets immediately after a power outage. This will prevent damage from sudden voltage spikes when power is restored.
After power is restored, wait 10–15 minutes before turning on appliances. This delay allows the voltage to stabilize and reduces the risk of equipment malfunctions.
Distribute the electrical load:
Avoid turning on all appliances at once after power is restored.
Start with smaller devices, such as lamps or phone chargers, and gradually connect larger appliances.
Use energy-intensive appliances, like washing machines or water heaters, during off-peak hours, such as at night, to minimize the load on the power grid.
Install protective equipment:
Voltage relays: these devices automatically disconnect appliances during voltage spikes and reconnect them once the voltage stabilizes.
Voltage stabilizers: designed to maintain a constant voltage level for device operation, they are essential for sensitive appliances but do not provide backup power.
Uninterruptible power supplies (UPS): they provide temporary power during outages using built-in batteries, ensuring continuous operation of critical devices.
Yes, voltage spikes during outages can cause irreparable damage to household appliances, especially to devices such as:
Refrigerators.
Washing machines.
Televisions.
Water heaters.
Computers and other electronics.
The cost of repairing or replacing such devices can be high, making surge protection devices a worthwhile investment.
Additional tips:
If an outage is expected, unplug important devices in advance.
Avoid using multiple high-energy devices simultaneously, as this can overload the system and cause emergency shutdowns.
