Jaivic ELECTROMECH ENGINEERING PVT. LTD.

Satpur, Nashik, Maharashtra

JAIVIC Capacitors are designed and manufactured with the latest technology by Jaivic Electromech Engg. Pvt. Ltd. At their most modern plant at Nasik. The Organisation is backed by a team of people having years of experience & expertise in the field. Hundred percent capacitors are thoroughly tested at every stage of manufacturing and all the routine and type tests are rigorously carried out as per IS: 13925 with latest version. This ensures excellent trouble-free service under most critical conditions of operation.

`JAIVIC H.T. Capacitors are used in various applications such as, in distribution systems in mines, Electricity boards, in Industries, for testing application etc. These are used across big motors for lift irrigation schemes, water supply etc. For Power Factor Improvement.

CONSTRUCTION & DESIGN OF H.T. SHUNT CAPACITORS

Each Basic element is wound in clean & dust free atmosphere on fully automatic HT Winding machine with the help of Electrical grade Imported biaxially oriented polypropylene film and a high purity soft annealed Aluminum foil.

The Winding of element is flat type. The Elements connected in parallel are formed in series groups to meet the voltage requirement.

The complete stack assembly is insulated with high grade electrical insulating material to get the desired insulation level. And total stack inserted in CRCA/SS container. For terminals of capacitor using high class glazed porcelain bushings.

The capacitor are dried under high vacuum and impregnated by synthetic liquid (PXE) under accurately controlled conditions.

Capacitors are designed to have very low loss generally less than 0.2 watts per kvar.

Every individual capacitor element is protected by fuse. In case of element failure during abnormal condition, only one element is disconnected, after disconnection of faulty element, the capacitor unit restores the normal operation within milliseconds with a slightly reduced output. Due to internal fuse the risk of case bursting is considerably reduced.

Salient Features of Jaivic Capacitors:

Self - healing PropertyM.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 QualityTightly 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.

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.
