3. Square Cap PFC Capacitors

square cap PFC capacitors
Square Cap PFC Capacitors

While the electrical energy is getting more scarce and expensive in the developing countries, the need for power factor improvement by installing capacitors is well understood by the users.

The improved power factor means:

  • Reduced line losses
  • Improved voltage profile
  • Reduced system current
  • Reduced cable sizes
  • Optimum usage of transformer
  • Monetary saving.

Havells is pleased to offer the SquareCap Series of Power Factor Correction Capacitors with enhanced performance. It helps you to achieve better economy by selecting an application-specific capacitor type.

The SquareCap Capacitor Series is now available in three designs viz.

  • Mini Master / Master: Normal Duty Capacitor for normal inductive linear loads.
  • Master Plus: Heavy Duty Long Life Capacitor for loads exhibiting some amount of non-linearity, presence of harmonics, medium size industries.
  • Champion: Super Heavy Duty Capacitor for non-linear arduous and fluctuating loads and systems containing higher degree of harmonics.

The SquareCap PFC Capacitors are ISI approved and comply with IS 13340 and the latest IEC specifications.

Basic Construction of the Capacitor:

  1. Film - The multi-layer Metalized Polypropylene Film (MPP) with heavy edge is manufactured in- house on the latest technology machines. This gives advantages of higher stability obtained from Zinc and longer shelf life obtained from Aluminum. Heavy edge construction of the film provides a better bonding between electrode and metal endspray (scooping), thereby enabling an increase in current carrying capacity and ensuring better withstanding to the electro- mechanical stress that occurs due to switching surges.
  2. Winding - The basic single phase capacitors are wound on computer controlled automatic winding machines and impregnated with polyurethane resin. Thus ionisation and carbon discharges are eliminated resulting in capacitors with highly stable characteristics and long life.
  3. Safety Systems
    A) Burst proof safety device - To prevent the capacitor from bursting in case of permanent breakdown caused by very high voltage in repetitive peaks and which can not be “self - healed” by the self-regenerative property, the capacitor is provided with a safety switching device, which disconnects the capacitor from the power source. When the internal pressure increases to an unsafe level it produces expansion of the bellow an snapping of the inner connection to the supply terminal, thereby cutting off the supply and avoiding possible bursting.
    B) Self-healing property - If the dielectric breakdown strength is exceeded locally at weak points, at pores or impurities in the dielectric, a dielectric breakdown discharge in the breakdown channel is sufficient to totally evaporate the thin metal coating in the vicinity of the channel. The rapid expansion of the plasma in the breakdown channel causes it to cool within few microseconds, thus quenching the discharge. This results in formation of insulated region around the faulty area- thus the capacitor regain its full operation ability.
    C) Due to polyurethane resin filling and non use of oil or PCB there is no risk of fire caused by spurting or leaking oil. In ecologically sensitive applications this design (dry) is a must.
  4. Modular Construction - Single units in excess of 6KVAr are made up of the required number of basic single phase modules. These are housed in a single metallic container and are connected to the three terminals which are brought out through the terminal block. This construction enables easy and inexpensive repair at site and also considerably saves on spares inventory cost.
