The Jaivic Capacitor Elements are manufactured using Metalized Polypropylene Film with Heavy / Reinforced Edge to provide excellent bonding between the electrode and end spray. The M.P.P. Capacitor Elements consist of a low dielectric, formed by pure polypropylene film. A thin Self-healing mixture of zinc and aluminum is metalized directly on P.P. under vacuum. This Technology ensures long operating life of the Capacitor Element. The Capacitor Elements are wounded in Air Conditioned, dust-free and humidity controlled Winding Room on totally automatic winding machines. Ultra modern pneumatic control on winding machine delivers best possible winding M.P.P.

The end Capacitor windings are contacted by spraying with Zinc Spray layer facilitating a high Current load and ensuring low inductance between the Terminals and Windings. The spraying on Capacitor winding is done on fully automatic X-Y manipulator and advanced high Velocity Arc Spraying System for coating of Zinc, which ensures uniform and fine coating.

Capacitor elements are thermally treated in an oven at 85 degree Celsius. Further these Elements are given A.C. and D.C. Voltages for Short Clearing and are tested for Capacitance Value and Dissipation Factor at 1 Khz. Elements are vacuum packed in laminated Aluminium Foil Bags.The Capacitor Elements are available in 5, 6, 7, 8 and 10 Micron M.P.P. Film.

Jaivic Capacitor Elements have high specific capacitance and high A.C. Voltage Withstand ability.

Self Healing Capability: Elements have excellent self healing capability whereby any electrical short circuit inside the element is cleared in milliseconds without affecting any change in capacitance or in other electrical parameters.

Low Loss Dissipation : The low loss dissipation factor associated with the heavy Edge M.P.P. Film keeps the losses low and extends the useful life of the Capacitor Element.

APFC Relay of Real Power (KW), which Produce energy & reactive power (KVAR) generated by Inductive Loads, which decreases the loading capacity & the efficiency of the Supply System. The Power Factor (PF) is defined as a ratio between the Real Power & the Total Power.

Power (KVA) Supplied by Electricity Boards consist of Real Power (KW), which Produce energy & reactive power (KVAR) generated by Inductive Loads, which decreases the loading capacity & the efficiency of the Supply System. The Power Factor (PF) is defined as a ratio between the Real Power & the Total Power.

Electricity Boards charge heavy Penalty to H.T. Consumer, if the Power Factor of the system is below a required minimum average value. Power Factor of the System can be improved by switching Capacitors as per KVA demand with the help of Automatic Power Factor Controllers. Modern Industries use Large Nos. of AC Motors, DC Drives, Rectifiers, Invertors, Compressors, Inductive Furnaces and Welding Machines, causing poor Power Factor of the System. The Reactive Power requirement in such Industries varies rapidly within every few cycles. The response speed of the conventional Power Factor Controller is not suitable to take care of rapid switching cycle. The Conventional Power Factor Control System incorporates Electromechanical Switches to Switch Capacitors and or not suitable for Fast switching where the load is rapidly changing. Also fast switching of Capacitors and Contractors results in inherent stresses on the Capacitors and on the Switchgear components. Uncompensated reactive power leads to poor Power Factor. Voltage instability, flickering, high current consumption, increased Maximum Demand, high losses, low electric supply, loading capacity and overrating of switchgears & cables results in high wear and tear and high maintenance cost.
