Voltage Transformers Dealers in Kalbadevi, Mumbai

DESCRIPTION:- Direct measurement of Voltage in high voltage system is not possible because of insulation problem of measuring instruments. It is also not possible to use voltage through the system directly for protection purpose due to its high value & high insulation problem. In such conditions voltage transformers are used. BASIC FUNCTIONS OF VOLTAGE TRANSFORMERS ARE . . . To reduce the line current to a value which is suitable for standard measuring instruments, relays etc. To isolate the Measuring Instruments, Meters, Relays etc. from high voltage side of an installation. To sense abnormalities in Voltage & give Voltage signals to protective relays to isolate the defective system.

In an Elent CVT, the AC mains powers the input winding which is widely separated physically from the isolated output winding. The input winding normally runs at very moderate Flux linkage levels. The output winding exhibits an intrinsic energy characteristic and this energy storage operates in conjunction with mains capacitor to produce self-generated AC flux field which is indirectly excited from the input winding. The result is instantaneous voltage regulation. No transient and spikes. Sinewave output. A perfect answer and remedy for every electronic equipment. SALIENT FEATURES No semiconductors or moving parts used, hence very high reliability No feedback control used Intrinsic current limiting and short circuit protection Output voltage correction within ½ Cycle ( 10 ms) from no load to full load for specified load and line variation Short term over load capability Energy storage for line loss up to 3 ms at typical loads Higher input voltage control range, for loads less than rated load Very high line transient/spike rejection capability and excellent input to output isolation characteristics Output floating (optional) Range Elent CVT is available in a wide range.. from 50 VA to 10,000 VA with load test conducted at unity power factor for all ratings. For configurations other than those mentioned above, please contact our office.
