Energy conservation has become a central issue of utmost priority all over the world today. Power being a major of expenditure in industries, it is equally important conserve power to maximum to sustain in competition of industrial goods. This can be done only by best utilization of available capacity of cables, switchgears & transformers, line losses, by reducing reactive current. The main source of reactive currents are inductive load, such as fan, indication motors, transformers, welding sets, fluorescent & gas lamps. Such kind of equipments draw not only active power (KW), but also reactive power (KVAR), from the supply. this reactive power is necessary for the equipment to operate correctly, could be interpreted as an undesirable burden on the supply. The vector total of these two is apparent power (KVA). P.F.(cos) = KW/KVA (The closer cos is to unity the less reactive power is drawn from the supply.

Application :
Construction : power capacitors and manufactured in perfectily dust free controlled environment using latest technologies and processes to ensure most reliable performance and impeccable long life in service. Use of high quality reinforced edge, zinc alloy MPP film on automated winding machines ensures good element winding. Material selection at every process is made judiciously towards this end.
Testings : Works is equipped with latest test laboratory where all kinds of routine test, type can be carried out as per Indian & international standard. This in house facility is used for ensuring reliability before release and development of new design, inputs processes.
