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.   SOLUTION : Jaivic Thyristorised Automatic Power Factor Correction System is a modern Powerful System constituting a Technological Breakthrough in the field of Power Factor Control. This new Modern System utilises Electronic Switching Element that switch Power Capacitor Banks into the new worth without creating switching transients. Connection to the network is performed with the help of ‘ZERO-CROSSING Detector’, providing smooth connection to the Capacitor Banks. There is no limit to the no. of switching operations, since the Electronic switching elements do not wear out or deteriorate during the switching process.         Technical Comparison :   Contractor Switching Thyristorised Switching     Network Compensation at extremely low voltage is not passible. Welding of the contactor contacts due to high inrush currents resulting in dangerous over compensations. Repeated and momentary Short Circuit currents due to capacitor Switching will have impact on the Life of the transformer. Contactors and Capacitors deteriorate in performance, resulting in down time and non availibility of compensation. Compensation at extreely low voltage is possible. No over compensation, under compensations and unbalanced compensation. No inrush current. Distribution transformer never subjected to short circuit current, life of the transformer increases. The Capacitor bank unit remains in useful operational service with maximum up time.          

Jaivic Power Factor Correction Capacitors are manufactured adopting the latest techniques, by our specially trained team of Engineers & skilled workers, in a well equipped modern plant at NASIK. Best available imported & indigenous material are used & production is carried out with utmost care in dust controlled air conditioned atmosphere. Experience of almost three decades in the field of manufacturing Capacitors, updated by new trends in technology, has made Jaivic Capacitors the most trusted and reliable.   Salient Features of Jaivic Capacitors:   Self - healing Property M.P.P. Capacitors are of Self-healing type as such eliminate possibility of permanent short circuit. Use Of Heavy Edge Film Jaivic Capacitors are manufactured using Tri-layer, Zn-Alloy/AL, Heavy edge, Low Loss Metalized film to provide better bonding between the electrode & end spray. Type & thickness of M. P. P. in making windings is selected in such a way that there is a very low drop in capacitance in working life of capacitors, making them the most reliable & stable capacitors. Winding Quality Tightly wound elements on imported winding machine result in Zero defect windings with accurate outputs.   Automatic Spray Automatic spray equipment makes it possible to have a continuous, uniform fine spray resulting in best possible end contact, in turn a very low tan delta value.   ADVANTAGES OF OIL FILLED CAPACITORS AGAINST DRY TYPE CAPACITORS Impregnation is done with the help of non-toxic friendly liquid at a very high vacuum resulting In following advantages: Impregnate fluid replaces air pockets in the zinc spray and help in eliminating partial discharges at the end contacts. Oil impregnated capacitors have much higher partial discharge voltage as compared to DRY TYPE. Jaivic impregnated Oil filled Capacitors are hermetically sealed, hence do not have any atmospheric influence compared to DRY TYPE. Capacitor wound elements are encased in metal containers of adequate thickness. The containers are hermetically sealed. To avoid rusting, metal containers are electroplated which also result in rust free attractive and durable painting. Penetration of liquid impregnate is thorough in comparison to semi liquid impregnate like Polyurethane, Flexible Epoxy etc. Because of its viscous nature. This makes these capacitors more stable because of improved Partial Discharge Inception voltage level. Level of liquid impregnate is maintained sufficiently above active elements, in comparison to semi-fluid impregnate. In liquid impregnate transfer of heat by conduction and convection mode is fast. This result in uniform cooling of capacitors. In turn reducing temperature rise of active elements. This gives an extra edge by increasing life of the capacitors and to take care of rugged service conditions. Free flow of impregnate inside capacitor containers, cooling of capacitor is uniform, making it very suitable for tropical and super tropical conditions.   GUARANTEE Jaivic Power Capacitors are backed by manufacturer's warranty against manufacturing defects for a period of 15 months from the date of dispatch from the Factory or 12 months from the date of installation whichever is earlier. AFTER SALES SERVICE Jaivic Power Capacitors will give trouble free performance. However in the unlikely event of any difficulty, Jaivic's after sales service will be readily available. * Continuous Technological changes may lead to product specification modification from time to time. * Standard range Capacitors designed for systems where harmonics not present for such application request for specially designed Capacitors     NOTE ON POWER CAPACITORS   Energy conservation   is the  most  important  for  all  because  the  cost  of  energy  for  industrial production  is reflected  in the cost  of goods produced,  it is in the interest of all,  particularly those engaged in any capacity in production to save as much as possible. There are many ways in which this can be brought about. One of the most effective ways from the industrial point of view is the installation of Power Capacitors. By installing Power Capacitors the Power Factor-can be improved, the improvement in Power Factor will decrease the maximum demand of the system.   What is Power Factor? Any industrial installation is fed from a high voltage system and comprises of:-   1)  A Transformer Station. 2)  “Resistive” loads-such as ovens, radiators, filaments, lamps, etc. 3)  “Inductive” loads-such as transformers, motors, etc.   It should be noted that the actual power consumed is lower than the Apparent Power and this ratio is called the Power Factor.                                 I.e. Useful Power   =   Power Factor < 1                                    Apparent Power   The advantage of a better Power Factor are multifold and all results in substantial economy in the Operation of electrical installation. 1)  Cutting down penalties for excessive consumption of reactive energy. 2)  Reducing line losses. 3)  Increasing line power carrying capacity. 4)  Increasing power available at supply transformer. 5)  Reducing Voltage drop.   Capacitors can be used as individual units or in Banks. Individual units of   1 to 30 kVAr ratings can be used for small units.  For  the  bulk  power consumers whose installed capacity  is more than 100 KW  may go for Banks of capacitors with or  without  automatic  P. F. control relay.  If the load fluctuation is more, as in Cement plants, Rolling Mills etc., they need Automatic Power Factor control relay to suit the load condition.   The saving effected by installing P.F. correction capacitors can be indicated by following example:   Consider: Maximum Load   125 KW Present P. F.     0.75 Required P. F.    0.99   Maximum demand at 0.75 P. F. = 125      =        166.6 kVA                                                                                                                                0.75 Maximum demand at 0.99 P. F.  =   125   =        126.26 kVA  0.99 Reduction in Max. Demand             =        40.34 kVA Saving in monthly charges @ Rs. 300/- per kVA (MSEB rates)    : Rs. 12,102/- Size of Capacitors required for this unit. (Multiplying factor from the table) For improvement of P.F.  -  From 0.75 to 0.99 i.e. 0.740 Therefore capacitor size =        125 x 0.740                                       =        92.5 kVAr , say 95 kVAr. Total Cost @ Rs. 170/- per kVAr (MPP Capacitors)              Rs. 16,150/- The entire cost is recovered in:      Rs.   16,150       =   1.33 Months.  = 40 Days   Rs.   12,102   If the penalty for low P.F. & rebate for Power Factor is taken into account this recovery is achieved in still less period of time.       If rebate for better P.F. is considered into calculation, this recovery will be in less than one Month period.
