    What Engineers Say

    Feedback from Power Projects Training Participants

    ★★★★★

    "It was a very nice training session about MV circuit breaker and generator breaker selection by the Power Projects team — with hand calculation as well as ETAP simulation. The session was not limited to that — it touched on grid islanding and several other topics with full theoretical concepts and simulation. Special thanks to Mr. Selva and Mr. Dijo."

    Adarsh Priyadarshi — Electrical Engineer, Hyundai Heavy Industries, South Korea
    ★★★★★

    "Being an electrical engineer from an operation and maintenance background, I was looking for institutes to learn Power System Studies. When I joined Power Projects' training program, I had very little knowledge of power system studies. By the end of the course, I learned a lot and am now able to execute projects on my own in just 3–4 months. I consider it the best decision of my life."

    Anand Thakur — Electrical Lead Engineer, Quest Global
    ★★★★★

    "I am thrilled to announce that I have successfully completed my MSc in Electrical Power Engineering with First Class, Distinction (81%). I am honoured to have done my final thesis on a real-case Industrial project with Power Projects. My sincere thanks to Selvakumar S sir for giving me this opportunity and spending your valuable time."

    Charitha Sasumana — Electrical Design Engineer, Arka11 Renewable Solutions Pvt Ltd
    ★★★★★

    "From a utility point of view, I lead compliance testing for synchronous machines, wind farms, and solar farms. I came across Power Projects' live webinars and decided to join. With an open mind that knowledge has no boundaries, I enjoyed it and can now probably design a solar farm site with a bit of help. Selvakumar S is one of the most technically knowledgeable people I have come across."
