Measurement-led diagnosis of harmonics, voltage events, flicker and power factor — for supply systems from 415 V upward. Every offer here starts with recorded data, not assumption.
Think of a power quality audit as a diagnostic. We measure harmonics, voltage events, flicker and power factor at your site, then trace whatever's causing trouble back to its source before it causes equipment failure, stoppages, or utility penalties. Every finding is checked against applicable IEEE and IEC guidelines, for facilities from 415 V upward with no fixed ceiling.
Each offer below can be commissioned standalone or combined into a full facility PQ audit. All are built on Class A instrumentation and referenced to the standard that governs the phenomenon being measured.
Full-spectrum voltage and current harmonic measurement at PCC and downstream feeders, with root-cause attribution to specific non-linear loads.
Formal compliance assessment against IEEE 519 voltage and current distortion limits at the point of common coupling, with a clear compliance position and remediation path.
Sag and swell event capture and classification, correlated against process trips and equipment nuisance faults.
Short-term and long-term flicker severity (Pst/Plt) measurement for facilities running arc furnaces, welders, large VFDs or other fluctuating loads.
Displacement and true power factor assessment with correctly sized correction, accounting for harmonic-rich loads that make naive capacitor sizing dangerous.
Power factor correction for ungrounded / floating neutral systems — marine vessels, offshore platforms, and process plants where standard grounded-grid PF correction assumptions do not apply.
Vendor-neutral specification of the correction technology — harmonic filters, PF correction, reactors, MV solutions or STATCOM — once the audit has identified the problem.
Tell us which offer fits your facility, or describe the problem you're seeing — we'll recommend the right scope.
