Anomaly detection in harmonics, transients, dips and swells, before they damage equipment.
Poor power quality costs industry through nuisance tripping, overheated cables and transformers, failed electronics and penalties for low power factor. Our engineers install portable class-A analysers at critical points of your network and record every event over a representative period.
We then turn raw data into an actionable report: the root cause of each disturbance, its impact, and engineered fixes such as harmonic filters, PFI correction, or protection and wiring changes.
What's included
Harmonic analysis
THD and individual harmonic measurement, checked against IEEE 519 limits.
Transients & surges
Capture of high-speed transients from switching, lightning and VFDs.
Dips & swells
Voltage sag and swell events, correlated with process trips and downtime.
Power factor & load
Load profiling, demand peaks, unbalance and power factor trend analysis.
Root-cause diagnosis
Correlation of events with equipment behaviour to pinpoint the true source.
Mitigation design
Specification of active/passive filters, PFI panels and protection upgrades.
Backed by S.A. Hamid & Co. since 1964
Engineering depth, in-house manufacturing and disciplined site execution from one accountable team.
Our approach
Scoping
Understand the symptoms, the single-line diagram and the critical loads.
Measurement
Install class-A analysers and log continuously at the agreed points.
Analysis
Correlate events, compare with the standards and identify root causes.
Remediation
Design and implement corrective measures, then verify with a re-measurement.

Frequently asked questions
No. Analysers are connected with clamp-on CTs and voltage leads during a short, safe window; logging then runs without any interruption.
Typically one to two weeks: around 7 days of logging plus analysis and reporting.
We report against IEEE 519 for harmonics and IEC 61000-4-30 / EN 50160 for measurement methods and voltage characteristics.
Yes. We design, supply and install harmonic filters, PFI panels and protection upgrades, then verify the improvement.
