50hz LT Servo Voltage Stabilizer, Certification : ISO 9001:2008, MSME

We offer our clients with the best quality servo voltage stabilizer which provide high efficiency and better performance. description : in spite of best efforts, no state electricity board can ensure for 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, winter season 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

• higher current produces higher losses in electrical motors which cause premature failure of winding.
• these higher losses of electric motors also increase the losses of cables, switches, transformers and other associated equipment.
• 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 motors 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. With the installation of servo voltage stabilizer, you will have the following additional advantages :

reduction in breakdown of electrical equipment technology adopted by us is far more superior then the conventional ones resulting in additional advantages and are pleased to give below certain facts to authenticate our claim. With the installation of stabilizer, there will be min. 60% reduction breakdown of motors. Contactor coils, bulbs, tubes etc,

energy saving there will be definite 5–10 %.energy saving by maintaining constant voltage at 390 / 400 volts depending upon the voltage variation.

reduction in mdi there will be definite reduction in mdi by 10 – 15 %, the mdi depends upon the voltage. Even if the high voltage occurs for half an hour in a month the mdi increases. With the installation of the stabilizer, the voltage will be controlled and mdi will also be controlled

improvement in power factor whenever the voltage increases above 440volts, there is a sharp reduction in power factor at least by square function.

winding our regulators are linear type, wound with heavy duty cross section copper strip as against supper enamel wire used in conventional dimmer status. The cross sectional area is almost 3 times and therefore the copper losses are much less. (i2 r; r = l/a ) . Coils are wound with paper covered electrolytic grade copper strip or synthetic enameled copper conductors. Cooling ducts are provided to keep the hot spot temperature as low as possible. Coils are dried in electric ovens. Rigid connection support and coil clamping is provided to ensure high short circuit strength.

core the core is constructed from low loss, cold rolled; grain oriented annealed laminations of electrical sheet steel conforming to the latest international standards. Special frame is built in house for clamping the core to reduce the magnetic noise as well as making the whole structure rigid and robust.

temperature rise power make automatic voltage controller are designed for max 30oc to 40oc temperature rise at top of oil whereas allowed limit is 50oc.

insulation precompressed board parmali board and japaneese insulation paper of best quality is used.
