The SEWA exam evaluates core engineering knowledge, practical field applications, and local regulatory compliance.
You should be prepared to answer questions on the following domains:
A 3-phase induction motor draws 40 A from the supply at 0.85 lagging power factor. If the stator losses are 1.5 kW and rotor copper loss is 800 W, the mechanical power developed is: a) 35.2 kW b) 36.5 kW c) 37.8 kW d) 38.1 kW sewa electrical engineer exam questions pdf portable
Circuits, machines, protection systems, and power systems.
Relays, circuit breakers, fuses, and grounding/earthing systems. ACB (Air Circuit Breaker)
: Calculate the voltage drop for a 250 kW load at a distance of 150 meters and select a suitable cable from a provided table. 3. Earthing and Protection Systems
Common abbreviations: (Variable Frequency Drive), ACB (Air Circuit Breaker), RMU (Ring Main Unit), and ATS (Automatic Transfer Switch). RMU (Ring Main Unit)
