Power Quality Audit

Power Quality Audits Identifies Power Quality issues. This will further help you to address reliability and stability concerns before they impact on your facilities performance and more important on bottom line of organization.


Power Quality Analysis

• Reduced Efficiencies
• Insulation Damage
• Pulsating torque’s in rotating Machinery
• Interference with communication, Control and Signal circuits
• Mal-operation of Equipment.
• Reduced Equipment Life & high maintenance Costs.
• Reduced Capacitor life /Capacitor failures
• Blown fuses & tripping of switch-gears.
• Increased Copper Losses

Benefits of Power Quality Analysis

• Assist in preventative and predictive maintenance
• Identify source and frequency of events
• Establish precise location and timing of events
• Develop maintenance schedules
• Monitor and trend conditions
• Analyze harmonics, Flicker, Transients frequency variation, voltage variations (sag &swell.)

Major Covered Parameters

• Peak Voltage and current, Frequency.
• Active, reactive and apparent power per phase and their aggregate.
• Active, reactive energy - consumed and produced (export / import).
• Harmonics for voltage, current up to the 50th order. • Flicker measurements.
• Power factor.
• Displacement factor and Tangent.
• Neutral current.
• Crest Factor for V and I.
• K factor for currents.
• V and I unbalance in %.
• Total Harmonic Distortion Factor.
• Inrush capture.
• Transients Recording

The advantages of the PQA

• The PQA final report provides a complete picture of the electrical system’s correct state of operation.
• The report is a tool of primary importance for preventive maintenance, in that it lists all the measures to be taken promptly when disturbances are detected, before the negative impact on production and the running of the equipment is felt

Process of PQA

• Program start-up & orientation (site)
• Onsite Assessment (site)
• Data collection from various location (Site)
• Final report preparation (Office)
• Submission & Presentation of report, (Site)
• Presentation of products & Solutions Along with application Guide & Notes (Site/office).
