Tech: Frequent power outages during the rainy season? Keep your TV, fridge, and AC safe like this..

During the monsoon season, issues such as power outages, voltage fluctuations, and sudden power surges become more frequent, especially in areas with aging electrical infrastructure. When power is restored after an outage, sudden voltage spikes can damage sensitive components in electronic appliances like TVs, refrigerators, and air conditioners. While many modern electronic appliances come with built-in safety features, their capabilities vary by model. Taking certain precautions can help protect circuit boards, compressors, and power supply units from damage.

**Check these points before buying a stabilizer**

Before purchasing an external voltage stabilizer, consult your product's user manual or specification label. Many modern refrigerators and inverter ACs can operate without a stabilizer within a specific voltage range. However, this does not mean they are completely immune to all electrical issues. If the voltage in your area frequently fluctuates beyond the specified limits, the manufacturer may still recommend using an external stabilizer.

Always choose a stabilizer designed for the specific appliance. For instance, an AC requires a stabilizer with higher capacity compared to one for a TV or refrigerator. Its voltage range and load capacity should align with the manufacturer's recommendations.

**Use the right protection for each appliance**

A voltage stabilizer continuously regulates low or high voltage, whereas a surge protection device protects against brief, intense voltage spikes. These devices serve different purposes and should not be considered substitutes for one another.

A TV can be connected to a high-quality surge protector that meets necessary safety certifications. Conversely, refrigerators and ACs should always be plugged into dedicated wall sockets and protected using appropriate safety devices; avoid using standard multi-plug extension boards.

For whole-house protection, a qualified electrician can also install a surge protection device in the distribution board. Proper earthing is also crucial; without it, safety devices may fail to function correctly in the event of a wiring fault.

What to do during frequent power outages?

If the power keeps going out and coming back on, switch off your TV and AC, and unplug them once it is safe to do so. If the power remains off for an extended period or the supply is consistently unstable, you may also unplug the refrigerator. However, keep the refrigerator door closed during this time to retain the cold air inside.

Do not immediately switch on appliances with compressors—such as refrigerators and air conditioners—once the power supply stabilizes. Wait a few minutes before reconnecting them. Many models and stabilizers come with a built-in 'restart delay' feature that prevents the compressor from restarting immediately. Never touch plugs, switches, or sockets with wet hands or while standing on a wet floor.

Do not ignore these warning signs

If lights in the house are flickering repeatedly, or if you notice sounds coming from sockets, a burning smell, a hot plug, or frequent circuit breaker tripping, it could indicate a problem with the wiring or power supply.

In such situations, stop using the affected socket immediately and have it inspected by a qualified electrician. Never attempt to open or repair stabilizers, sockets, or electronic appliances yourself. If water has entered the switchboard, external AC wiring, or wall outlet, seek help from a professional technician immediately.

Precautions to take before the monsoon begins

Before heavy rains start, ensure that your home's wiring, earthing system, and distribution board are inspected. Secure the external AC wiring according to installation guidelines, but never cover the outdoor unit in a way that obstructs its ventilation. If you suspect that an appliance has been affected by a power surge, check for signs such as error messages, unusual noises, or reduced cooling performance. Timely inspection can prevent a minor electrical issue from escalating into major damage.
