Audit & Engineering Study Services

Measurement-driven audits and engineering studies — identifying risks, inefficiencies, and compliance gaps before they become problems.

Our approach

Understand first. Act on evidence.

Every effective engineering solution begins with accurate measurement and honest assessment. pqExcel's audit and engineering study services are designed to give you a clear, data-backed picture of your electrical system's performance — identifying what needs attention, why, and what to do about it.

Our audits are conducted by experienced engineers using calibrated instruments — delivering structured reports with findings, analysis, and actionable recommendations. Whether you need to verify compliance, identify power quality issues, assess electrical safety risks, or establish an energy baseline, we bring the right methodology and the right tools to every engagement.

Audit before solution — pqExcel recommends an audit or measurement study before any mitigation or system solution is proposed. This ensures every recommendation is grounded in actual site data — not assumptions.

What we offer

Our audit & study services

Five structured services — each delivering a clear, actionable report to support engineering decisions, compliance requirements, and safety improvements.

🔍

Power Quality Audit

A comprehensive assessment of your electrical system's power quality — measuring harmonics, voltage quality, power factor, and disturbance events to identify issues and verify compliance with IEEE 519 and EN50160 standards.

Deliverables
Site measurement using power quality analysers
Harmonic spectrum and voltage quality analysis
Load profile and power factor assessment
IEEE 519 and EN50160 compliance report
Recommendations for mitigation

Harmonic & Reactive Power Study

A detailed engineering study focusing on harmonic generation sources, distortion levels, and reactive power demand — providing the data foundation for correct sizing and selection of AHF, SVG, APFC, or hybrid mitigation systems.

Deliverables
Harmonic source identification and quantification
THD and TDD measurement and analysis
Reactive power demand profile
Solution sizing and selection recommendation
Engineering report with mitigation options
🌡

Thermography Audit

Infrared thermal scanning of electrical panels, switchgear, transformers, bus bars, and connections — detecting hotspots, loose connections, and overloaded components before they cause failures, fires, or unplanned downtime.

Deliverables
Thermal imaging of panels, switchgear, and connections
Hotspot identification with temperature readings
Risk classification — critical, moderate, low
Photographic evidence with thermal images
Corrective action recommendations

Relay Co-ordination Study

A systematic review and optimisation of protection relay settings across your electrical distribution system — ensuring selective, time-graded fault clearance that minimises disruption, protects equipment, and maintains system stability during fault conditions.

Deliverables
Single line diagram review and data collection
Short circuit and fault level calculations
Protection co-ordination analysis
Recommended relay settings for each device
Time-current characteristic curves and report
💧

Arc Flash Study

An incident energy analysis of your electrical distribution system — determining arc flash hazard levels at each equipment location, establishing safe working boundaries, and supporting selection of appropriate Personal Protective Equipment (PPE) for electrical workers.

Deliverables
System data collection and single line review
Incident energy calculations per equipment location
Arc flash hazard classification and boundary determination
PPE category recommendations
Arc flash labels and engineering report
Our philosophy

Measure before you act — every time

At pqExcel, every solution recommendation is preceded by measurement. Audits and engineering studies are not add-ons — they are the foundation of every engagement.

This approach ensures that solutions are sized correctly, investments are justified by data, and outcomes can be validated through post-implementation measurement.

📈

Accurate diagnosis

Site measurement reveals the true state of your electrical system — not what is assumed based on equipment specifications or historical incidents

🔍

Right solution, right size

Measured data ensures mitigation systems are correctly sized and specified — avoiding over-engineering or under-performance

🏅

Compliance documentation

Structured audit reports provide documented evidence for regulatory compliance, utility requirements, and internal audit purposes

Validated outcomes

Post-implementation measurement confirms that solutions have achieved their design targets — giving you confidence in the investment
