Muskaan Engineers is a name known for reliability and continuous improvement in the field of rolling contact type Automatic Voltage Controllers, Electroplating and Chemicals Process Rectifiers and Special Purpose Transformers. The systems are designed and supervised by a team of qualified engineers having decades of experience to achieve best possible quality to total customer's satisfaction.
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 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 up to 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 and 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 stabilizer and maintaining 390/400 volts, the motor will operate smoothly drawing 15 - 20% lesser current and correspondingly the relay setting can be reduced by 15- 20%. In case single phasing occurs, the relay will trip in 40-50 seconds. The Motor can withstand the high current for this period and will be safe. Also, the relays, contactors, switchgears ,etc. incorporated with the motor will be safe.
