Servo Voltage Stabilizers
Servo
Voltage Stabilizers
(Linear Type and Rolling Type)
Inspite of best efforts, no state electricity board can ensure constant voltage to the customer because of long and inadequate distribution lines and irregular load pattern on distribution transformers. Generally voltage is low during day time and high during night hours. Moreover on holidays, peak hours, rainy day and when agricultural and industrial load is switched off, the voltage rises sharply which is more dangerous.
This higher current affects the electrical motors (particularly smaller capacity motors upto 7.5 H.P.) in three ways:
- Higher current produces higher losses in electrical motors which causes premature failure of winding
- These higher losses of electric motors also increase the losses of cables, switches, transformers and other associated equipments.
- For smooth continuous operation of motors, over load relays are usually set at 20% higher setting.
Types of Servo Voltage Stabilizer
Air Cooled Servo Stabilizer
Oil Cooled Servo Stabilizer
Advantages:

- The Wave form distortion is Zero.
- They generate Very low internal impedance
- There is Negligible phase shift.
- There is No-effect on Power factor.
- Output regulation of ±1%
- Fast correction rate.
