  • No reduce in output
  • Specially vacuum processed, oil impregnated design
  • Suitable for flexi banking
  • Suitable for frequent switching operation
Applicable standards
  • IS 13585 (Part 1) : 2012 IEC 60931-1 :1998 1Ø/3Ø APP (Film + Foil) type Heavy Duty Capacitor for Power Factor Improvement& Harmonic Filtering.
Principles of Power Factor Correction :
  • A vast majority of electrical loads in low voltage industrial installations are inductive in nature. 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 :
    • Higher electricity cost due to levy of penalties / loss of incentives
    • Higher KVA demand from supply system as given in figure 2
    • Higher voltage drops in the system
    • Increase in the losses of Transformers, Switchgear and Cables
    • Increased current flow for a given load
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 :
  • 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.
  • Every Capacitor is designed for a specific lowest and highest ambient temperature.
  • It is always recommended to adopt forced air cooling in detuned reactor filter panels.
  • Life of Capacitor decreases when operated beyond the limits.
  • 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.
