Introduction

In spite 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 days 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:

  1. Higher current produces higher losses in electrical motors which causes premature failure of winding.
  2. These higher losses of electric motors also increase the losses of cables, switches, transformers & other associated equipments.
  3.  For smooth continuous operation of motors, over load relays are usually set at 20% higher setting.

With the installation of the Servo Controlled Voltage Stabilizer and maintaining 395/400 volts, the motor will operate smoothly drawing 16 – 20% lesser current
