Three Phase Automatic Voltage Controller, Power : 60 W

Description of POWER Make Automatic Voltage ControllerServo Stabilizer primarily consists of the followingLINEAR, 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 also using self lubricating Carbon Roller Assemblies instead of ordinary Carbon Brushes which offers more reliability and trouble free performance of the equipment.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. ELECTRONIC CONTROL CIRCUIT AND METER PANEL Automatic Voltage Controller consists of very simple electronic control voltage 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. Effect of Unbalanced Input Voltage between Phase to Phase Industrial units situated in residential / commercial area's and are not having their own distribution transformer, have the problem of unbalance input voltage between phase to phase and many have the problem of frequent failure of three phase motors. Normally unbalanced input voltage problem persist for few hours a day and will have the following effects on the three phase motors.

• With 5% Unbalanced Input Voltage between phase to phase - the LOAD will be unbalanced and the capacity of the motor reduces by 40%.
• Consumption of the three phase motor will increase by 20 - 25%.
