It is an electrical appliance which is designed to deliver a constant voltage to a load at its output terminals regardless of the changes in the input or incoming supply voltage. It protects the equipment or machine against over voltage, under voltage, and other voltage surges. Voltage stabilizers regulate the fluctuating input voltage before it could be fed to the load (or equipment which is sensitive to voltage variations). The output voltage from the stabilizer will stay in the range of 220V or 230V in case of single phase supply,within given fluctuating range of input voltage.
Voltage stabilizers play a crucial role in ensuring a stable and consistent electrical supply to various devices and systems. Here are some common applications of voltage stabilizers:
A 3-phase oil-cooled voltage stabilizer regulates and stabilizes voltage across three phases, using oil as a cooling medium to dissipate heat efficiently.
A 3-phase air-cooled voltage stabilizer maintains stable voltage levels across three phases, utilizing air cooling for efficient heat dissipation.
