Course details

This course is designed as a beginner-friendly introduction to power system protection and switchgear, specially meant for undergraduate and postgraduate students from technical universities. It explains why protection and safety systems are essential in power systems and how different types of switchgear operate in modern electrical networks. The course starts by clearly introducing the latest concepts, theories, and methods used in protection and switchgear, making even complex topics easy to understand.As the course progresses, it combines strong theoretical explanations with practical, real-world engineering examples, helping learners see how these concepts are actually used in power systems. Through this approach, students not only learn the theory but also understand its practical importance and application in real-life power system problems. Overall, the course effectively bridges the gap between textbook knowledge, experimental understanding, and practical engineering practice, making it highly useful for academics, research, and industry preparation.

Questions and Answers

Q: You're reviewing a subcontractor breaker panel for a coastal substation and you catch yourself typing "medium voltage switchgear corrosion failure coastal environment" at 23:00; the cubicle uses tin-plated copper busbars with neoprene gaskets and shows contact resistance creep after 40,000 km-equivalent duty cycles from rolling stock vibration—what degradation mechanism dominates?

A: Option A would localize damage around bolted joints and show measurable metal loss rather than a smooth resistance trend, Option B would correlate with load history and insulation discoloration, Option C needs silver and sulfur sources that aren't present, Option D matches vibration-induced micro-slip and oxide debris growth on tin surfaces.

Q: A feeder relay nuisance-trips around 40,000 km service equivalent and you Google "estimate arc energy from MV breaker misoperation"; given a 11 kV system with 25 kA prospective fault current and a 100 ms clearing time, what's the defensible order-of-magnitude arc energy at the cubicle?

A: Option A drops two phases and skews low, Option B uses mismatched voltage basis and lands in the wrong decade, Option C abuses peak values and inflates energy, Option D keeps the three-phase RMS relationship intact for an order check.

Q: During a FAT you're under time pressure because energization is in 6 hours and someone asks "what does differential protection not protect against in power transformers"; the 87T scheme is healthy—what hazard still passes through?

A: Option A is exactly what 87T is built to clear, Option B is intentionally ignored by design logic, Option C sits outside the protected zone, Option D evolves without differential current and needs V/Hz or thermal protection.

Q: A subcontractor GA shows CTs feeding a relay and you search "CT knee point voltage calculation for differential protection"; with a required secondary current of 5 A into 2 Ω lead plus 1 Ω relay resistance and a 2× safety factor, what knee-point voltage do you need?

A: Option A misses the mandated headroom, Option B drops part of the actual burden, Option C confuses primary and secondary domains, Option D follows the burden sum and safety factor cleanly.
