Salient Features of Priya Capacitors

Winding

Winding/Elements are produced in Air Conditioned, dust-free, humidity controlled winding room. Metallised Polyptopylene Film with Heavy/Reinforced Edges is used to provide excellent bonding between the electrode and end spray. Heavy edge has high current carrying capacity and withstands electromechanical stresses caused by switching surges better.

Self . Healig

When a breakdown occurs ot o weok point in the dielectric, on arc is struck between two adiacent metol coating in the immediote vicinity of the puncture evopor. ates very quickly and, in doing so, extends the length of the arc. Both the impregnating agent and a tiny part of the dielectric also decompose in this arc, and a zone of high gas-pressure is formed, which forces the metal vapour away from the surface of the cooting thus-preventing condensation in the immediate vicinity of the puncture. This rise in pressure and the rapid increase in the length of the arc cause lost de-ionization at the point of puncture, ensuring that the short circuit current is generally interrupted within 5-10 microseconds irrespective of the amount of energy whiich is available. Apart from a small soever, and, owing to the metal-free zones which form' in the immediate vicinity of the puncture, the insulation level of the dielectric of the capacitor is instantly restored to its full volue. The capacitor then remains fully serviceable after one or even more such "self healings"

Vacuum Drying & Oil Impregnation

The assembled elements undergo Vacuum Impregnation. Non - Toxic, Non-hazardous, Non-flammable, Non-PCB, Impregnent is used for Impregnating.

Vacuum Oil Filling

Capacitors are impregnated in vacuum tanks of controlled temprature under very fine vacuum' Purified Oil is allowed to flood in the impregnating chamber and the oil outomoticolly gets filled in the capacitor leaving no air space within the container to ensure better Performance and longer life.

Tesing Laboratory

Testing facilities for conducting all routine tests as per relevant BIS Specification are available. In addition, the following type tests are carried out at our works

• Test for Capacitor Losses
• Thermal stability Test
• Endurance Test
