Units Up To 200 Kvar Are Offered Giving Benefit Of Kvar To Volume Ratio And Thereby Reducing Installation Cost And Space. These Capacitors Are Used For Compensating Transmission Line Losses As Well As For Power Factor Improvement. Each Capacitor Unit Consists Of Number Of Elements In Series / Parallel Combination With Internal Fuses. Each Element Is Wound With High Quality Hazy Bopp Film As Dielectric And High Purity Aluminum Foil As Electrode. Extended Foil Construction Is Adopted To Enhance The Life Of Capacitor. Normally The Electrode Material I. E. Aluminum Foil Has Sharp Points At Slit Edge Which Causes High Stress At The Sharp Points Causing Damage To The Capacitor. To Overcome This Phenomenon The Edge Of Aluminum Foil Is Folded Such That No Sharp Points Left Over. This Folding Forms A Ring Named As ‘Corona Ring’. After This, Capacitor Is Impregnated With NON-PCB, NON-TOXIC Bio gradable, Eco Friendly Oil Under Vacuum Which Enhances Life Of Capacitor. Such Capacitors Under Go Rigorous Testing Before Painting And Dispatch To Concern Customers.   During The Process Of Repairs Of These Capacitors The Capacitors Are Opened First. Then The Entire Elements Are Checked Visually And Those Elements, Fuse Of Which Blown, Are Removed From The Stack. These Faulty Elements Are Replaced With Good Elements And The Capacitor Is Put For Initial Testing. During This Testing If Any Other Element Is Faulty It Also Blows Off. Then The Same Is Also Replaced With Good One. After This The Capacitor Is Put For Final Testing And After Passing The Testing The Capacitor Is Sealed, Painted And Dispatched To Concern Customers.

  The Metalized Polypropylene Film means that the capacitor with electrodes formed by vacuum evaporation of metal deposited directly onto the dielectric strength of polypropylene film was put to very effective use to produce avery compact and the light weight construction of capacitor. The construction of this type of capacitor is like having one sheet of Polypropylene Film in which an upper part is metalized with aluminum (Al) or zinc (Zn) with standard thickness having 0.2μm. Once we made a kind of sheet then it is wound on mandrill with specified number of layers as per calculation. After that, for outer connection purpose like making series or parallel connection we spread the zinc (Zn) spray on the top of the winding as well as bottom of the winding.  Due to this type of construction there is no possibility of occurrence of air packets or bubbles or moisture content in between the conducting & non-conducting material. That iswhy in this case there is no requirement of vacuum impregnation process. The self-healing property is the main property of Metalized polypropylene film. With the help of Metalized poly propylene film in capacitor, the arc discharge extinguishes without causing large damage. If defect area is small then capacitor will be in service without any interruption and self-healing property of Metalized polypropylene film is itself gives small area deflects. Such Capacitors can use under very high electric stress, which allows to store a large amount of energy in small volume. On the other hand, when there is a possibility of rapidly in creasing in voltage, current and temperature beyond its certain limit then insulation of that capacitor may get break down or some times degraded. Due to this internal short circuit, this part is of no use. But capacitor is heated and continually operated with slightly low capacitance. Self-healingis convenient feature for capacitor. But if the capacitors frequently operate at higher voltage, current, or temperature.Then it will reduce its capacitance more rapidly and finally it effects on frequency of that filter network.

Typical examples are motors, transformers, drives & fluorescent lighting. Such loads consume both active and reactive power. The active power is used by the load to meet its real output requirements whereas reactive power is used to meet its magnetic field requirements.The reactive power (inductive) is always 90° lagging with respect to active power as shown in figure 1. Figure 2 & 3 show the flow of kW, kVAr and kVA in a network before and after installation of Capacitors. Active and Reactive power always flow in every electrical installation. This means that the supply system has to be capable of supplying both active and reactive power. The supply of reactive power from the system results in reduced efficiency due to• Increased current flow for a given load • Higher voltage drops in the system• Increase in the losses of Transformers, Switchgear and Cables • Higher KVA demand from supply system as given in figure 2 • Higher electricity cost due to levy of penalties / loss of incentives   It is therefore necessary to reduce & manage the flow of reactive power to achieve higher efficiency of the electrical system and reduction in cost of electricity consumed. The quick & cost effective method of reducing and managing reactive power is through improvement of power factor by installing Power Capacitors. Concept of reduction in kVA demand from the system is shown in figure 3.   Application PF correction in LV network LV Dynamic Automatic power factor correction panels (APFC) (Contactor / Thyristor switched) Fixed power factor correction Tuned and detuned Harmonic filters   Safety Internal element fuse design Non polluting, nonhazardous NPCB Capacitor fluid Externally fitted Discharge resistors Steel enclosure for protection from live terminals Standard ratings of Capacitors Output: 5, 7.5, 10, 12.5, 15,20,25 KVAr / 41 S and 440 Volts with 151 and CE marking Higher ratings can be supplied on request. Effect of temperature rise Every Capacitor is designed for a specific lowest and highest ambient temperature. Life of Capacitor decreases when operated beyond the limits. Capacitor should not be exposed to heat and must be kept in a well- ventilated position to avoid overheating. Capacitors used in conjunction with series reactor in detuned filter application, the location of reactor affects the surrounding air temperature, Since the reactor radiates heat, it should be placed always above the Capacitor or in a separate column in order to protect capacitors from excessive heating. It is always recommended to adopt forced air cooling in detuned reactor filter panels.   Effect of over currentThe maximum allowed RMS current is given in technical data ofthe Capacitor. Operating the Capacitor beyond, will reduce the life of the Capacitor. Higher current drawn by Capacitor means increased losses. This results in heating of the Capacitor, thereby, reducing its life. Effect of over voltage Operating the Capacitor beyond permissible limits of over voltage will damage the Capacitor. Some levels of over voltages are accepted only for a short duration but they reduce the life of the Capacitor. Such levels must not occur for more than 200 times in the life time of a Capacitor.   Protection of Capacitors Capacitors have to be protected against short circuit currents by using external fuses having adequate current rating. It is recommended to use HRC fuses, having current rating of 2 -2.5 times the rated current of Capacitor. Switching of Capacitors When the Capacitor is switched in to the network, high inrush currents flow. Fast acting contactors which are capable of handling the high current level should be used. Capacitor duty contactors (connected with resistors) are better suited, since they damp the inrush currents. Contactor / switch gear ratings should be minimum 1.5 times of the rated current of Capacitors. Discharging Capacitors Capacitor must be discharged before it is re-energized to avoid superimposition of voltage over residual voltage. This helps to increase the life of Capacitor. The Capacitor voltage must reduce to less than 75V within 3 minutes. This is achieved by connecting an external discharge resistor across the Capacitor terminals. No disconnecting device be connected between the Capacitor and discharge resistor.  Earthing of Capacitor An Earthing terminal has been provided on the body of the Capacitor to be used for earthing. It is recommended to earth the Capacitor for safety purpose. Resonance Capacitors connected in harmonic rich environment are prone to resonance related problems, leading to failure of Capacitors. Under such conditions detuned reactors in series with Capacitors are preferred. Maintenance The Capacitors should be kept in a well- ventilated area, free from any corrosive medium. Terminal connections should be tightened as recommended and cleaned regularly for better performance and enhanced life   De-tuned Harmonic Reactor Iron Cored Reactors are used along with Capacitors in De-tuned harmonic filter applications. RatingDetuned Reactors are available in 5%, 6%, 7% and 14 % ratings.Features • Linearity up to 200% • Compact size and convenient mounting • Low losses • Low noise level • Tested as per IS 5553 and IEC 60076 - 6 Safety • Thermal switch provided to protect the Reactor from overheating. • E class insulation
