The circuit of a voltage stabilizer

The circuit of a farady step voltage stabilizer basically consists of a voltage sensor. It is configured to detect the rise or fall of the ac power transformer voltage to dangerous levels. As soon it senses a risky input voltage, it immediately energizes the relays connected to it. These relays in turn swaps and switches the appropriate winding terminals of the auto transformer to correct and stabilize the output voltage. Thus the appliance which is connected to the output of the voltage stabilizer circuit always receives a safe, tolerable voltage and is able to function reliably, irrespective of the fluctuating input voltages.
