Power Quality and Harmonics: IEEE 519 and IEC 61000

It is a free-to-learn, self-paced course in electrical power quality: voltage sags, swells, transients, flicker and unbalance, and harmonics from drives, UPS, IT loads and inverters. It covers THD and TDD calculations, resonance and detuned capacitor banks, IEEE 519-2022 compliance at the point of common coupling, IEC 61000-4-30 measurement, Python analysis, harmonic filters and a harmonic study in OpenDSS, with notes, worked problems and a data centre project.

It is for electrical design, maintenance, utility and data centre engineers and senior electricians who deal with drives, UPS systems, capacitor banks, generators or harmonic complaints. Commissioning engineers, energy engineers and consultants who sign off IEEE 519 or grid code compliance will also find it useful.

You need three-phase power, per-unit values and power factor at the level of a diploma or degree in electrical engineering, plus school algebra. No paid software is needed: a spreadsheet, Python with numpy and pandas, and the free OpenDSS simulator are enough, and Google Colab runs the Python and OpenDSS work in a browser.

The course covers the IEC 61000 family (61000-2-2 and 2-4 compatibility levels, 61000-3-2 and 3-12 equipment limits, 61000-4-30 measurement, 4-7 harmonics and 4-15 flicker), EN 50160, and IEEE 519-2022 with IEEE 1159 and IEEE C57.110. The standards are explained in our own words and no tables are reproduced, so read the edition your contract names before signing a compliance report.

About 24 hours at your own pace: about 15.6 hours of video plus notes, worked problems and practice tasks across 14 modules and a final assessment. The optional data centre harmonic compliance project takes about 16 hours more.

The course is free to learn, and you can earn a verifiable certificate of completion by finishing the modules and passing the 15-question final at 60 percent. Each certificate has a unique number, a QR code and a public verification page that shows the course, the modules covered and the final score; it is not an IEEE or IEC credential.

Measure for at least a week with an IEC 61000-4-30 Class A analyser at the point of common coupling, calculate the short-circuit ratio Isc/IL there, and compare the weekly 95th percentile of the 10 minute TDD and voltage THD with the IEEE 519-2022 limits for that ratio and bus voltage. Modules 8 to 10 work through each step with numbers, and the project applies it to a data centre.

It leads to power quality engineer, electrical design engineer, data centre electrical engineer and utility connections engineer roles, where IEEE 519 and IEC 61000 experience is a common requirement in job adverts. Data centre growth, drive retrofits and solar and battery connections keep demand strong in the Gulf, across South Asia and in Europe and the Americas.

Yes. Learning costs ₹0 in India: every module, the written notes, the practice tasks and the final assessment, with no card and no trial period. The only paid item is the optional EDWartens Certificate of Completion, ₹599 including GST for this intermediate course, paid in rupees through Razorpay, and only if you want it after passing the final assessment.
