Power Factor: Power factor is defined as the cosine of the angle between voltage and current. Power factor is the measure of how effectively the incoming power is used from total/apparent power in an electrical system. A high power factor indicates that the power supplied to the electrical system is effectively used.  A system with low power factor doesn’t effectively consume the incoming electric supply and results in losses. There is no power factor involved in DC circuits due to zero frequency. But, in AC circuits, the value of power factor always lies between 0 and 1. Cause of Low Power Factor: Some causes of low power factor are  a) The presence of harmonic current in the system reduces power factor.  b) Improper wiring leads to three-phase imbalance causing low power factor.  c) When the system is loaded lightly, the voltage increases, increasing the magnetization current demand of the machine. This causes a poor power factor in the system.  d) The current drawn by inductive load

Energy Audit:   As per Indian Energy Conservation Act 2001, Energy Audit is defined as: “The verification, monitoring and analysis of use of energy including submission of technical report containing recommendations for improving energy efficiency with cost benefit analysis and an action plan to reduce energy consumption.” The main purpose energy audit is to increase energy efficiency and reduce energy related costs. Energy audit is not an exact science. It involves collection of detailed data andits analysis.Energy audit is a fundamental part of an energy management program in controlling energy costs. Need of Energy Audit: * The three top operating expenses are energy (both electrical and thermal), labour and materials. * Energy would emerge as a top ranker for cost reduction. * primary objective of Energy Audit is to determine ways to reduce energy consumption per unit of product output or to lower operating costs. * Energy Audit provides a “ bench-mark” (Reference point) for managi
