Introduction to Stabilizer:
What is a Voltage Stabilizer?
Why Voltage Stabilizers Are Needed?
- Permanent damage to the equipment
- Insulation damage to the windings
- Unwanted interruption in the load
- Increased losses in cables and associated equipments
-rating life of the appliance De
- Malfunctioning of the equipment
- Longer working periods (as in case of resistive heaters)
- Reduced performance of the equipment
- Drawing large currents which further lead to overheating
- Computational errors
- Reduced speed of motors
How Voltage Stabilizer Works?

- Check the power rating of the apparatus that which you are going to be used with a stabilizer, by observing the nameplate details (Here are the samples: Transformer Nameplate, MCB Nameplate, Capacitor nameplate etc.) or from product user manual.
- Since the stabilizers are rated in
(Same as the case as kVA rated in Transformer instead of kW), it is also possible to calculate the wattage by simply multiplying voltage of the appliance by maximum rated current. kVA
- It is recommended to add a safety margin to stabilizer rating, typically a 20-25 percent. This could be useful for future plans to add more devices to the stabilizer output.
- If the appliance is rated in watts, consider a power factor while calculating
rating of stabilizer. On the contrary, if stabilizers are rated in kW instead of kVA , multiply the power factor with voltage and current product. kVA
