ENGINEERING CAREER AND STUDY MATERIALS

1. Strain type insulator arc used where the conductors arc (A) dead ended (B) at intermediate anchor towers (C) any of the above (D) none of the above. 2. Conductors for high voltage transmission lines are suspended from towers (A) to reduce clearance from ground (B) to increase clearance from ground (C) to reduce wind and snow loads (D) to take care of extension in length during summer.  3. Boosters are basically (A) inductors (B) capacitors (C) transformers (D) synchronous motors.  4. Which of the following is not the distribution system normally used (A) 3 phase-4 wire (B) 3 phase-3 wire (C) Single phase - 3 wire (D) Single phase -4 wire.  5. Skin effect results in (A) reduced effective resistance but increased effective internal reactance of the conductor (B) increased effective resistance but reduced effective internal reactance of. the conductor (C) reduced effective resistance as well as effective internal reactance (D) increased eff...
