Single Phase Servo Controlled Stabilizer
Stabilizers for unbalanced load and supply systems can be used where the three phase voltages vary in an unbalanced manner. These Stabilizers have three nos. single phase individually coupled with drive motors. Each drive motor along with electronic controller is entrusted to take care of one phase to neutral voltage and load variation independently. In other words these stabilizers are a combination of three nos. Single Phase Stabilizers connected in STAR configuration.
