POWER QUALITY STUDY

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

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

• Higher energy consumption and High Current Load.
• Penalties Incurred for exceeding Tariffs.
• Production Quality & Quantity losses.
• Financial Losses due to stoppage.
• Increase in Reactive power consumption.
• Reduced life cycle of Equipment.
• Additional investment for Over sizing of equipment.
• Energy wastage.
• Increased Maintenance and Service cost.
• Over Voltage/Under voltage/Sag/Swell/electrical Noise/Surges/spikes

• To Improve Power Factor & system efficiency.
• To Avoid Break-downs & production Interruptions
• To Avoid excess Energy consumption.
• To remove Harmonics, Surges & Transients from electrical Network.
• To Avoid Voltage/frequency fluctuations & PLC Hang-up.
• To Avoid Transformer overheat, Capacitor burst, Trip Etc.
• Savings in Energy Bills due to reduced Losses & KVA demands.
• Accurate Measurements by Installed Meter.
• Better Production Rate and Quality due to reduced interruption.
• Enhanced Life cycle of Electrical network & component.
• Maximize Plant distribution Capacity.

• 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 .)
• Ensure equipment performance
• Assess sensitivity of process equipment to disturbances
• Evaluate performance against specifications

• 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 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.

• 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).
