Power Quality Study and Diagnostics

A study to find the cause of trips, overheating or a low power factor, with full scope under IEEE 519-2022, EN 50160 and ITIC classification. We run the measurement, interpret the data and recommend mitigation: the report ends in concrete actions.

How we work

Six steps, one actionable report

Class A measurement over 7 to 10 days

We install a Fluke 1770/1775/1777 analyzer (Class A per IEC 61000-4-30) at the point of interest. Continuous measurement at 10-minute resolution over the period IEEE 519 recommends.

IEEE 519-2022 + EN 50160 assessment

Compliance analysis against Table 1 (voltage) and Table 2 (current) of IEEE 519-2022. Cross-check against EN 50160 for voltage quality. Identification of harmonic sources by spectral pattern.

K-factor and loss calculations

K-factor for transformer sizing. Estimated harmonic losses in cables (skin effect) and transformers (eddy currents).

Events on the ITIC curve

Every recorded sag/swell is classified against the ITIC (CBEMA) curve to determine whether each event fell in the no-interruption region (the equipment should keep running), the prohibited region (overvoltages that can damage it) or the no-damage region (the equipment may stop, but should not be damaged).

Complete technical report

A Word document with 20+ sections: cover, table of contents, executive summary with green/yellow/red traffic lights, harmonic tables, trend charts, glossary and prioritized recommendations.

Recommendations with Danfoss solutions

If mitigation is needed, we put concrete options on the table: AAF active filters, AHF passive filters, AFE VFDs or a combination. Each option with an estimated cost, payback and alternatives.

// How we get started

Three steps and typical lead times

The study is scheduled without stopping operations. Lead times are typical for one measurement point; with several points they are confirmed in the proposal.

01 Typical time 1 day

Short technical visit

We review the symptom (trips, overheating, power factor), the single-line diagram and the points where it makes sense to measure.
02 Typical time 7 days

On-site measurement

A Fluke Class A analyzer logging at 10-minute intervals for a full week, to capture operating peaks, weekends and maintenance.
03 Typical time 1–2 weeks

Report and recommendations

A technical report with the diagnosis, the assessment against IEEE 519-2022 and EN 50160 and the prioritized mitigation options.

If what you need is to prove compliance to the utility, see our IEEE 519 compliance audit in Panama.

If the study confirms excessive harmonics, mitigation usually means harmonic filters, active or passive.

// FAQ

What clients ask before we start

Short answers to the questions that usually come up in the first technical conversation. Exact lead times are confirmed in the proposal.

Q01 How is this study different from an IEEE 519 audit?

The study looks for the cause of a specific problem (trips, overheating, low power factor) where it happens. The IEEE 519 audit focuses on proving compliance at the point of common coupling to the utility.

Q02 Does the plant have to stop for the measurement?

Usually not: the analyzer is installed while the plant runs normally. We coordinate safe access to the panel where it connects with your maintenance staff.

Q03 I already have a CSV file from a Fluke analyzer. Is it useful?

Yes. With the free power quality check you upload the exported CSV and receive a first assessment. If more detail is needed, the full study is proposed.

Q04 What is delivered at the end?

A technical report with an executive summary, harmonic tables, trend charts, events on the ITIC curve and prioritized recommendations, each with an estimated cost and payback.

Is your plant seeing trips, overheating or a low power factor?

Before investing in filters or power factor correction, measure. A well-run study saves you money spent in the wrong place.
