The problem of fluctuation in supply voltage is a menace to electricalequipments. Despite best efforts by various Electricity Boards, voltage atconsumer premisses is never constant irrespective of the distribution beingHT or LT.It is invariably observed that during day time the voltage remainsquite low and during night it goes up. These fluctuations result in frequentbreakdown of equipments causing lower production, higher rate of rejectionand above all loss of energy.The magnitude of supply voltage should bereasonably constant to ensure long life of electrical equipments and optimumutilisation of production system. In order to ensure that accurate voltage isavailable, the use of SERVO VOLTAGESTABILIZER is must.These highlyaccurate, fast and reliable Servos ensure that an output voltage with anaccuracy of:!: 1% is made available forequipment.

Under Voltage

Reduces the capacity of the motorand increases motor losses, thereby raisingthe operating temperature of motor andreducing motor life.

Application Type

AC Motors

Over Voltage

Causes sharp drop in P.F.atleast bySquare Function of voltage. Low systemP.F.decreases overall system efficiency.

Lighting Equipment Service life eut by many times.Normal lighting level demandsmore luminaries

Resistance/InductionHeating

Available heat varies by the square of thevoltage, slows production, requires longwarm-up time.

Heater element deteriorates fromexcessive oxidation, regardless ofthermostatic control.

Welding Equipment Weld-time cycle must be lengthened toprevent cold-weld.

Will be over-heated, resulting in poorquality welds.

Rectifier Loads Electroplating deposition rate increaseslikewise.

Electroplating deposition rate dropsconsiderably.
