Servo Voltage Stabilizer uses an advance electronic controlled servo motor concept to govern a motorized variable transformer. Because of the motors involved, there is a small delay in voltage correction. However, output voltage accuracy is usually ±1% with input voltage changes of up to ±50%. This type of technology tends to be extremely effective when considering large three phase applications, as it is able to maintain its accuracy of all these phases, despite of input voltages balance and load balance at any power factor.
