Power cuts, voltage fluctuations and surges can become more frequent during the monsoon, particularly in areas with ageing electrical infrastructure. When electricity returns after an outage, an abrupt
voltage change may affect sensitive components inside televisions, refrigerators and air conditioners.
Modern appliances often include built-in protection, but its limits vary by model. A few precautions can reduce the chances of damaged circuit boards, compressors and power supplies.
Check the Appliance’s Operating Voltage Range
Read the product manual or specification label before buying an external voltage stabiliser. Many modern refrigerators and inverter ACs support stabiliser-free operation within a stated voltage range.
This does not mean they are protected against every electrical condition. If the local supply regularly falls outside the supported range, the manufacturer may still recommend an external stabiliser.
Choose a stabiliser designed for the appliance concerned. An AC requires a considerably higher-capacity unit than a television or refrigerator. Its voltage range and load capacity should match the manufacturer’s requirements.
Use the Right Protection for Each Appliance
A voltage stabiliser regulates sustained high or low voltage, while a surge protection device is intended to handle brief voltage spikes. These products serve different purposes and should not be treated as interchangeable.
A TV can be connected to a good-quality surge protector carrying the appropriate safety certification. Refrigerators and ACs should use dedicated wall sockets and suitable protection rather than ordinary multi-plug extension boards.
An electrician can install a surge protection device at the distribution board for wider household protection. Proper earthing is equally important because protective equipment may not work as intended when the wiring is faulty.
Switch Off Appliances During Repeated Power Cuts
If electricity is repeatedly going off and returning, switch off the TV and AC and disconnect them when it is safe to do so. A refrigerator may also be unplugged during an extended or unstable outage, but keep its doors closed to retain the cold air.
Wait a few minutes after the supply becomes stable before reconnecting compressor-based appliances such as refrigerators and ACs. Some models and stabilisers already include a restart delay, which helps prevent the compressor from restarting immediately.
Never touch plugs, sockets or switches with wet hands or while standing on a damp floor.
Watch for Electrical Warning Signs
Flickering lights, buzzing sockets, burning smells, warm plugs and frequently tripping circuit breakers can indicate a wiring or supply problem. Stop using the affected outlet and contact a qualified electrician.
Do not attempt to open a stabiliser, socket or appliance for repairs. Water entering a switchboard, outdoor AC connection or wall outlet requires immediate professional attention.
Prepare Before the Monsoon
Have loose connections, earthing and the distribution board inspected before heavy rains begin. Keep outdoor AC wiring protected according to installation requirements, but never cover the outdoor unit in a way that blocks ventilation.
After a suspected surge, check appliances for error messages, unusual sounds or interrupted cooling. Early inspection may prevent a minor electrical problem from causing further damage.
