Before diving into PDFs, let's understand the target. SEWA (Sharjah Electricity, Water and Gas Authority) conducts a standardized written exam for fresh graduates and experienced engineers applying for various grades (typically Engineer Grade I, II, or III).
Q: A three-phase induction motor draws 40A at 0.8 PF lagging. What is the real power?
Many online forums, Telegram channels, and websites claim to offer “SEWA electrical engineer exam questions PDF upd.” In reality:
Therefore, relying on such PDFs is not only ineffective but potentially harmful.
Instead of chasing unauthorized PDFs, candidates should focus on verifiable, ethical sources:
Here are representative questions often found in these PDFs to help you study.
Q1. The primary function of a Buchholz relay is: A. To protect transformers from external faults. B. To protect transformers from internal faults like inter-turn faults. C. To measure oil temperature. D. To isolate the transformer during overload. (Correct Answer: B)
Q2. Which type of insulator is generally used in high voltage transmission lines? A. Shackle Insulator B. Egg Insulator C. Suspension Insulator D. Pin Insulator (Correct Answer: C)
Q3. In a 3-phase system, if the power is measured by two wattmeters and one wattmeter reads zero, the power factor of the load is: A. 0 B. 0.5 C. 0.866 D. Unity (Correct Answer: B - When PF is 0.5, one wattmeter reads zero)
Q4. For a transmission line, the standing wave ratio (SWR) is defined as: A. Ratio of maximum voltage to minimum voltage. B. Ratio of maximum current to minimum current. C. Ratio of maximum power to minimum power. D. Both A and B. (Correct Answer: D)
Q5. Which circuit breaker is most suitable for capacitor bank switching? A. Air Blast Circuit Breaker B. SF6 Circuit Breaker C. Vacuum Circuit Breaker D. Oil Circuit Breaker (Correct Answer: C - Vacuum Circuit Breakers are excellent for capacitive current switching due to their ability to handle high frequency transients)
