 Inspite of best efforts, no state electricity board can ensure constant voltage to customer because of long and inadequate distribution and irregular load pattern on distribution transformers. Generally Voltage is low during day time and high during night hours. Moreover on holiday, peak hour’s 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 moters up to 7.5 H.P) in three ways. 

• Higher current produces higher losses in electrical moters 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.
•  With the installation of the stabilizer and maintaining RATED voltage, 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 relays, contractors, switchgears, etc. incorporated with the motor will be safe.                                           

 

• DESCRIPTION OF AUTOMATIC VOLTAGE CONTROLLER:  

• PEC servo Stabilizer primarily consists of the following:- 

• 1.  Linear plus /Minus Type Vertical Rolling Contact Voltage Regulator      
•                                                                                                                                                         
• In our regulator we are using heavy section of electrolytic grade rectangular copper strip instead of copper wire to minimize the losses & increase the efficiency of equipment. We are using self lubricating Carbon Roller Assemblies instead of ordinary Carbon Brushes which offers more reliability and trouble free performance of the equipment. 

• 2. Double Wound Buck / Boost Type Series Transformer 

• In our Buck/ Boost transformer we are using CRGO lamination to minimize iron losses and coils of Buck / Boost transformer are wound with heavy section of multi strips electrolytic copper to minimize copper losses for getting better efficiency of the equipment. 

• 3. Electronic Control Circuit and Meter Panel.  

• PEC Automatic Voltage Controller consists of very simple electronic control circuit for monitoring and controlling voltage, repair & maintenance of which is very easy.
• The regulator and Buck / Boost transformer are oil cooled, housed in same or separate sheet steel tanks. Radiators are provided for effective cooling. The coils of voltage regulator & Buck / Boost Transformers are vacuum impregnated and oven dried as per IS.
