Voltage fluctuations are a common problem in Delhi, especially during summer when power demand peaks. These fluctuations can damage your expensive AC's compressor and PCB. But does every AC need a voltage stabilizer? Let's find out.
What is an AC Voltage Stabilizer?
A voltage stabilizer is an electrical device that maintains a constant voltage level to your AC, protecting it from voltage spikes, drops, and fluctuations. It ensures your AC gets the right voltage (typically 180-260V) regardless of the input voltage.
Does Your AC Need a Stabilizer?
YES - You Need One If:
•You live in an area with frequent voltage fluctuations•Your area has voltage below 180V or above 260V•Your AC doesn't have built-in voltage protection•You use a non-inverter AC (especially older models)•Your MCB trips when the AC starts•Multiple appliances trip when AC turns onMAY NOT Need One If:
•Your AC has built-in SVG (Stabilizer Free Operation) - like newer Daikin, LG, and Samsung models•Your area has stable voltage (always 200-240V)•You already have a whole-house voltage stabilizerDelhi Areas Prone to Voltage Fluctuations
Areas like older parts of Delhi (Chandni Chowk, Karol Bagh), newly developing areas, and areas with heavy industrial load often experience voltage issues. Check with your neighbors or electrician.
How to Choose the Right Stabilizer
Rule: Stabilizer capacity = AC capacity × 1.5 (minimum)
| AC Tonnage | Minimum Stabilizer |
|---|
|-------------|-------------------|
| 1 Ton | 1.5 kVA (1500VA) |
|---|
| 1.5 Ton | 2.5 kVA (2500VA) |
|---|
| 2 Ton | 3.5 kVA (3500VA) |
|---|
