How to fix voltage fluctuations

Why does my voltage keep fluctuating?

Loose or corroded connections either at the house or on the powerlines can cause voltage fluctuations. This is often seen as flickering lights. Low voltage due to overloading on the network, loose connections, or too small a conductor wire carrying power to your house may cause dimming of your lights.

How do you stabilize voltage in a circuit?

The concept of stabilization involves in adding or subtracting the voltage to and from the mains supply. For performing such task stabilizer uses a transformer which is connected in different configurations with switching relays.
