Measurement-driven audits and engineering studies — identifying risks, inefficiencies, and compliance gaps before they become problems.
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.
Harmonics, voltage quality, power factor — IEEE 519 & EN50160 compliance
Detailed harmonic analysis and reactive power assessment
Infrared thermal scanning for hotspot detection and risk assessment
Protection device settings for selective, reliable fault clearance
Incident energy analysis and electrical safety assessment
Five structured services — each delivering a clear, actionable report to support engineering decisions, compliance requirements, and safety improvements.
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.
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.
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.
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.
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.
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.
Site measurement reveals the true state of your electrical system — not what is assumed based on equipment specifications or historical incidents
Measured data ensures mitigation systems are correctly sized and specified — avoiding over-engineering or under-performance
Structured audit reports provide documented evidence for regulatory compliance, utility requirements, and internal audit purposes
Post-implementation measurement confirms that solutions have achieved their design targets — giving you confidence in the investment
