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 current The 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.  Rating Detuned Reactors are available in 5%, 6%, 7% and 14 % ratings.

Steep fronted waves (lightning or switching) on transmission as well as distribution networks, can cause inter turn insulation failure of rotary machines and transformers. Surge Capacitors provide surge protection to high voltage motors, transformers and generators by limiting the voltage rise. Hence Surge Capacitors are used as protective devices for protection of power system equipments. Surge Capacitors are designed taking into consideration its application to operate under severe stringent power system conditions. Connecting surge Capacitors between line and ground at the motor / transformer / generator terminals in shunt, prevent the equipments from damage due to voltage surges. For a more comprehensive protection scheme, Surge Capacitors may be used in conjunction with surge arrester. This surge pack modifies both the wave shape and magnitude. Lightning arrester takes no current from the line during normal operation. When a surge occurs, the arrester turns on to provide a discharge path. When the surge disappears, the arrester turns off. The main advantage of a Capacitor is that there is no time delay in turning on as it  always conducts. The disadvantage is that the amount of current it can handle is limited to a  few amps, depending on the Surge Voltage. For this reason, an arrester should always be  installed with a Capacitor to protect Capacitor from intense surges. These Capacitors are virtually maintenance free, needing only occasional cleaning of bushings and painted surface and ensuring adequate tightening of electrical connections. Temperature rise of surge Capacitor is to be monitored continuously. Surge Capacitors are never protected with any type of fuse or any protection as itself is a protective device.    Features  • Low losses • World Class Raw Materials  • Manufactured in state of art infrastructure • Volume Optimized and highly Reliable  • Trouble free Long life performance  • Low noise level  • Environmentally friendly.    Ratings  Single Phase Capacitors units  • 0.125 to 0.5 uF  • Up to 40 kV  • 50 Hz or 60 Hz  • Indoor or outdoor use.
