Power Quality Audit

A Power Quality Audit is a measurement and analysis study of the electrical supply quality at a facility — evaluating parameters such as voltage harmonics, current harmonics, voltage sags and swells, transients, flicker, power factor, and frequency variations against acceptable limits defined by applicable standards. Poor power quality can cause equipment malfunction, premature failure of motors and transformers, nuisance tripping of protective devices, increased energy losses, and production disruptions.

A power quality audit identifies the sources and severity of power quality disturbances — determining their impact on facility operations and recommending corrective measures such as harmonic filters, power factor correction equipment, voltage stabilisers, or uninterruptible power supplies. It is particularly relevant for manufacturing facilities with variable speed drives and non-linear loads, data centres, hospitals with sensitive medical equipment, and any facility where power quality issues are causing unexplained equipment failures or energy efficiency problems.
