ENERGY ENHANCEMENT BY USING UTC SERVO VOLTAGE REGULATORS
Three Phase And Servo Voltage Transformers
You can now enhance the quality of power, as well as save power, by using UTC servo voltage regulator. It is a distortion less, servo controlled stabilizer available up to 2500 KVA capacity. It works on the principle of sine-wave superimposition. It bucks or boosts the incoming voltage by superimposing a variable voltage having the same waveform. UTC servo voltage regulator is the proven solution to all above problems caused by voltage fluctuations & unbalance. It saves your costly equipments & processes from detrimental effects of fluctuating & unbalanced voltage & gives you mental peace to concentrate on more important business issues. Above all, UTC servo voltage regulator can substantially add to your bottom-line by saving up to 20% power, depending on the incoming power quality.
WORKING PRINCIPLE OF UTC SERVO VOLTAGE REGULATORS
Constructionally, it consists of two transformers, one is a variable autotransformer (dimmer) and the other is a buck-boost transformer, as shown in the single line diagram. In case there is a voltage fluctuation, the microprocessor based controller moves the carbon brushes on the dimmer unit to tap the equivalent of voltage to be added or subtracted to the mains voltage. This voltage is then fed to the primary of the buck-boost transformer which, adds or subtracts it from incoming voltage, so that output voltage is always maintained at its set value. Since the control of voltage is carried out independently for each phase, therefore any voltage unbalance also gets corrected. Furthermore, each phase can be loaded independently, therefore our servo voltage regulator is suitable for unbalanced load conditions as well.
