Variable transformers are devices used in electrical power systems to adjust voltage levels. They are commonly employed in transmission and distribution networks to increase or decrease the voltage as required for efficient power transfer and utilization. These transformers offer the flexibility to vary the turns ratio and adjust the output voltage within certain limits, making them essential components in maintaining stable voltage levels under changing load conditions. Variable transformers play a crucial role in regulating voltage in industrial applications, ensuring reliable operation of electrical equipment and minimizing power losses.
