Course Summary, Final Q&A, and Certification of Completion
Accreditation
Al-Khobraa certified. On completion delegates receive an Al-Khobraa certificate of achievement.
What do Al-Khobraa electrical and power engineering courses cover?
The portfolio covers power generation, transmission and distribution, low- and high-voltage systems, power system protection and relay coordination, switchgear and transformers, motors and drives, SCADA and smart grids, and electrical safety and arc-flash control.
Who should attend an electrical or power engineering course?
These courses suit electrical engineers and technicians, substation and grid operators, protection and control specialists, maintenance supervisors, plant and facilities engineers, and utility or contractor staff working on generation, transmission or distribution assets.
How long are electrical and power engineering courses, and where are they held?
Most Al-Khobraa electrical and power engineering courses run over 5 days. The exact duration, dates and city for this course are listed in the dates section on this page. Public sessions run across Saudi Arabia — Riyadh, Jeddah, Al-Khobar, Jubail and Yanbu — as well as regional and international venues, with live virtual classrooms available on request.
What certificate will I receive?
Delegates who complete the course receive an Al-Khobraa certificate of completion, issued by a Saudi-registered training provider. Al-Khobraa also delivers internationally accredited programmes; where a course carries an external awarding body such as PMI, CIPS, ILM or IOSH, that body is named on the course's own page.
Can electrical and power engineering training be delivered in-house for our team?
Yes. Any Al-Khobraa electrical and power engineering course can be delivered in-house at your own premises anywhere in Saudi Arabia or the GCC, with the content, dates and language of delivery tailored to your team. Al-Khobraa is an approved HRDF (Hadaf) provider, so eligible Saudi employers can seek training support. Contact us for a quotation.
