This video summarizes the calculation problems for ground fault currents involving grounding capacitors, a common mistake in the short-answer and calculation-type questions of the Electrical Engineer practical exam. The key point of this video is not simply memorizing formulas, but rather avoiding being misled by the term "delta connection" in the problem and accurately analyzing the capacitor connection and capacitance that serve as the basis for the calculation. This will be particularly helpful for those preparing for the following: Students preparing to solve short-answer questions for the Electrical Engineer practical exam Students repeatedly solving calculation problems for the Industrial Engineer practical exam Those who know the ground fault current formula but frequently get confused when applying it to problems Those who find it difficult to distinguish between grounding capacitors, 3-wire collective capacitance, and delta and Y connections Join the Yellow Pig Success Squad and Jeil Electric Technology Academy to review the frequently asked short-answer questions for the 2026 Electrical Engineer practical exam one by one.
