Power Quality Audit

Power Quality determines the fitness of electrical power to consumer devices. This will further help you address reliability and stability concerns before they actually impact on your facilities performance and more important on the bottom line of the organization.
Without proper power, an electrical device may fail, malfunction or not operate at all.

The Poor Power Quality can Affects You?
• Higher energy consumption and High Current Load or fluctuation.
• Production Quality & Quantity losses.
• Financial Losses due to the stoppage.
• Increase in Reactive power consumption.
• The reduced life cycle of Equipment/damage.
• Energy wastage.
• Short Circuit
• Increased Maintenance and Service cost.
• Degradation of electrical system
• And many more issues

Why is POWER QUALITY audit important?
You may not be aware of issues facing in your “ELECTRICAL SYSTEMS” due to poor power quality. Diagnosis of power quality is important to

• Protect electrical equipment safety.
• Trace the area which is creating problems.
• To avoid any electrical system hazards.
• Improve Power Factor & system efficiency.
• Avoid Break-downs & Voltage/frequency fluctuations Interruptions
• Save on-going excess Energy consumption.
• Remove Harmonics, Surges & Transients from electrical Network.
• 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 Lifecycle of Electrical distribution system network & component.
• Maximize Plant distribution Capacity.


• Load Study
• Harmonics (Vthd & Ithd)
• Earth-Pit resistance Test (at mains transformer), Every Control Panel and Distribution bound level.
• Reactive Power Analysis
• Power Parameters
• Line Disturbances (Transient, Sags, Swells at main Transformer)
• Captive Power Assessment
• Load Distribution
• Thermography
• Problem Investigation
• PQA Report
• Inferences & Recommendation

The Power Quality Analysis following
• Data collection from the site.
• Harmonic measurements along with specific harmonic filtering at normal operating conditions.
• Voltage Improvement & stability case study.
• Three phase balancing study.
• Surge & Transient Protection, study.
• KVA Capacity Release
• Harmonic reduction requirement if any.

Harmonics Analysis
A harmonic analysis involves the use of computer programs to identify and predict potential harmonic problems and mitigation techniques. The study will also look at different operating points as well as the system.

Surges & Transient Analysis:
It’s conducted to record the transient s & surges of 1KV – 6KV magnitude.
Voltage Dips Swells Analysis:
Its record the short term dips & swells along with magnitude & duration

Reactive Power Analysis:
The calculation records the desired reactive power at distribution &load end. This will give precise reactive power & maintain near unity power factor at PCC. Reduce losses & resonance in network

Captive Power Analysis:
Calculate the desired captive power and synchronize the captive power to cater to peak demands. Reduce utility surcharge & fuel consumption

Load Flow Analysis:
The process conducted to predict power flow magnitudes, power factor, voltage levels, and losses in branches of the system based on the specified operating conditions.
