A small investment that not only pays for itself but generates huge savings in power costs year after year after year.

Brief Introduction

In recent years there has been increasing awareness among large power users like H.T. Industries, commercial establishments & shopping complexes of the need not only for uninterrupted power but also quality power and its efficient utilization what with the continuously increasing tariffs which make power very expensive today.

Now this issue has assumed even more urgency and importance with the Electricity Boards imposing huge penalties for LOW POWER FACTOR’ which is one of the major factors contributing to large power losses and wastage of scarce energy in the electricity system.

Low Power Factor Problem

  • Input / Output voltage and frequency
  • UPS and battery mode / status
  • Load capacity
  • Estimated runtime based on connected load
  • Minimum maintenance
  • Easy installation
  • Long operational life

The Solution

The heart of the Cos APFC is a microprocessor based controller which on a continuous real time basis senses the quantum of powerfactor shortfall and selects the right capacitor bank to provide the precise value of correction required at each point of time through a series of high performance contactors. A capacitor bank consists of a single or group of capacitors of different values required for varying degrees of power factor correction.

We use world class capacitors of advanced Technology which are specially designed for reliable operation in this very demanding application. Typically the state of the art microprocessor based controller described earlier can control up to 6 to 12 stages of capacitors of various values to achieve precise power factor compensation.

The PFC has a user friendly display which indicates various load details in addition to power factor like current, voltage and other parameters. The system has all the various safety, alarm and trip functions necessary for safe operation. Cos APFC units also have short circuit protection through MCCBs and fuses. Cos APFC systems are available from 15 KVAR to 300 KVAR ratings in various configurations for different applications.
