in kVAr), use the trigonometric power triangle relationship:

Circuit breakers (SF6, Vacuum, and Air Circuit Breakers) and their ratings. Here are typical examples of questions found in

Maximum allowable resistance values for consumer installations and substations.

: The structural architectural footprint for Main Distribution Boards (MDB) requires clear spatial spacing. An MDB room must maintain a minimum front clear path of 1.0 to 1.5 meters for maintenance safety. It detects internal faults like short circuits, inter-turn

A Buchholz relay is a gas-actuated safety device mounted on the piping between the transformer main tank and the conservator. It detects internal faults like short circuits, inter-turn faults, and insulation breakdown by sensing gas accumulation or oil surges. Question 3: Cable Sizing & Regulations

Multiple-choice questions (MCQs) and occasional short-answer descriptive questions. Duration: Typically 1 to 2 hours.

The design question often combines several of these topics into one complex scenario, such as "Design the feeder protection for a 500kVA transformer" or "Calculate the required generator capacity and earthing conductor size for a commercial building."
