Does stabilizer save electricity bill

Before going to takel this question, first understand that what is a stabilizer?

A stabilizer is a type of an auto transformer which is used to supply constant voltage in the output of the stabilizer. It's only work on alternative current because it's has a transformer in it.

Why transformer is not working on direct current?

In other words we can also define as--
It is an electrical device which used to constant the fluctuating voltage either 220-240 volt on single phase and 380-400 volt on the three phase. It's an compact device which are connected before an appliance. The AC voltage stabilizer is also called automatic voltage regulator, which regulator the voltage either the voltage is fluctuating or not.

There are various of stabilizer are present in the market. But, they are all only two types single phase or three phase. The three phase are of two versions like balanced load version and unbalanced load version.

Why we need a stabilizer?

Any electric device is needed rated voltage and current for better function or performing.
The rated voltage or current means that is only a quantity of voltage and current which are written on the name plate of any device(like transformer, Motor). When the rated voltage is not taking by the device then it's can't working properly, or there is some heat produce in the winding of the device (like transformer, Motor). For example, when the electric blub is not taking rated or 220-240 volt then it's output or luminance reduce and also reduce it's life. And also In the motor and transformer when low voltage supply through it, it's winding become heated and insulation start melt due to this it's winding become short, which cause short life of device.
Hence, it's is necessary to maintain voltage on the device to better performance and longer life.

Principal of stabilizer:-

The stabilizer is mostly working for two purpose are-

1. Boost operation:-

The operation in which the voltage is increased from the under voltage, this process is known as boosting operation. In this process there is step down transformer which are connecting in such a way that primary voltage is added to the secondary voltage. As shown in the figure-

The stabilizer is consist of an transformer, relay, and electronic circuit. Here supply is given to the primary winding of step down transformer. And the transformer is connecting in such a way that it's secondary voltage is added to the primary voltage as show in the figure carefully.

2. Buck operation:-

In the buck operation, the operation in which the decreased form the over voltage. In this operation we also use step down transformer which are connected in such a way that primary voltage reduce by the secondary voltage. As shown in the figure--

This is used to reduce the overloaded voltage which harm the electrical device.

Now comes to our questions that Does stabilizer save electricity bill ?

So it's answer is NO, because there various equipment connected in the stabilizer like transformer, relay and various circuit, which taking current. So, it's is clear form here that our electricity is also consumed by the stabilizer but not more. Thus we conclude that our electricity bill is increased by using stabilizer but we can reduce it by taking best quality stabilizer which are of higher efficiency.
