Journeyman Lineman Test
Questions With Correct Answers
1. Delta SecondaryVoltages?
Answer> Delta doubles (Phase to phase is always 2 x Phase to neutral.)
2. WYE Secondary Voltages?
Answer> Phase to phase is always 1.73 x phase to neutral
3. Shoring and Latter placement?
Answer> 3 4 5-Shoring Latter extends 3' past rest
point
At 4' you need a ladder
At 5' you need shoring 1
Ladders every 25'
4. What causes resistance in a conductor?
Answer> The Type
Copper/ACSR, Size, Length, and Temperature (the more heat more
resistance.)
5. How do you take a capacitor off line?
1/
15
, Answer> Open oil switch or open cutout with load break. The internal resistor should
bleed the voltage to 50 volts or less in 5 min. Then shunt and ground the capacitors.
6. What do capacitors do?
Answer> Improve power factor, when the current is lagging the voltage.
7. Why does a recloser stay energized longer on the 3rd or 4th shot?
Answer> To allow a fuse to blow if there is a tree fault and also to narrow down the
area of the fault after the fuse blows.
The reason it holds open is to allow an sectionalizer to open cause it operates under no
voltage.
8. What determines the strength of a magnetic field?
Answer> the current
9. Types of over current protection?
Answer> Circuit breaker, Recloser-OCR, and Cutout.
10. Can you look at a circuit breaker and determine the line voltage?
Answer> NO (Because they are not rated in voltage just amps)
11. In CPR how many chest compressions are needed to how many breaths?-
Answer> 30 Chest compressions to 2 Breaths 30-2
12. How would you parallel two regulators?
