Servo voltage Stabilizers are the automatic voltage regulators
. These servo stabilizers regulate the output power. It produces voltage output as per customers requirement. Servo voltage stabilizers are effective solution for voltage fluctuation problems. These are designed in such a way that the fluctuating current is maintained with specified output voltage. These are completely distortion free and the regulation is unaffected by the load power. Servo stabilizers have high voltage protection. If the input is going beyond the limit the output also goes beyond the limit is worst cases. These Servo Stabilizer sense input and output condition and cutoff the output supply of the stabilizer. In this way stabilizer protects the connected appliances.
Before selecting any stabilizer one should know how much power is needed. By taking an inventory of all the essential electrical loads and doing a basic electrical load evaluation, a customer can get a good idea about the usage of the power which is needed to produce. It is also important to know the power fluctuations which are the present problem in India. If you have to select the input voltage window and the power consumption it becomes very necessary to about the fluctuation problem. The Servo Stabilizer Manufacturers manufactures these stabilizers in such a way that they are very efficient, safe and control the fluctuations in better way. They also save power. Voltage servo stabilizers are high end systems that provide high correction speed of voltage control, combined rugged design and quality components. There are many manufacturers who market servo voltage stabilizers in India. These are gaining importance in India as these are becoming very essential for all the appliances due to severe fluctuations.
CVT known as constant voltage transformer uses a unique principle of ferroresonance. When the iron core of a transformer is at saturation, there will be relatively large changes in winding current which results in very small changes in magnetic flux. Winding current and magnetic flux are proportional to the input and output voltage. This is nothing but when there are voltage changes in input voltage result in small changes in output voltage, this is the fundamental purpose of an automatic voltage regulator. These constant voltage transformers use a tank circuit which is composed of a high voltage resonant winding and a capacitor to produce a nearly constant average output with differing input. This ferroresonant approach is attractive due to absence of active components, which are relying on the square loop saturation of the tank circuit to absorb variations in average input voltage.
