Journeyman Lineman Test
Delta Secondary Voltages?
Delta doubles (Phase to segment is usually 2 x Phase to neutral.)
WYE Secondary Voltages?
Phase to phase is constantly 1.73 x segment to impartial
Shoring and Latter placement?
Three 4 five-Shoring
Latter extends 3' beyond rest factor
At four' you want a ladder
At five' you need shoring
1 Ladders every 25'
What causes resistance in a conductor?
The Type: Copper/ACSR,
Size, Length, and Temperature (the greater heat greater resistance.)
How do you take a capacitor off line?
Open oil switch or open cutout with load wreck. The internal resistor must bleed the voltage
to 50 volts or much less in 5 min. Then shunt and ground the capacitors.
What do capacitors do?
Improve electricity aspect, whilst the modern is lagging the voltage.
Why does a recloser live energized longer at the 3rd or 4th shot?
To permit a fuse to blow if there may be a tree fault and also to slender down the vicinity of
the fault after the fuse blows.
The reason it holds open is to permit an sectionalizer to open reason it operates beneath no
voltage.
, What determines the power of a magnetic discipline?
The contemporary
Types of over modern-day protection?
Circuit breaker, Recloser-OCR, and Cutout.
Can you have a look at a circuit breaker and determine the road voltage?
NO (Because they're not rated in voltage just amps)
In CPR how many chest compressions are had to how many breaths?
30 Chest compressions to 2 Breaths 30-2
How would you parallel regulators?
Leave them on the step they had been at, lock them down, and turn them off. Once the work
is entire placed lower back to manual. OR take one or both off line and do the identical
issue.
LTC is powered by way of?
PT by way of volts
Safe working limits with ropes?
If the breaking strength of a rope is five,000lbs and the assigned WLL is 1,000lbs then the
safety factor is five.
Color of carrier lines on automobiles?
Red- Emergency
Blue- Service
Green- Electrical
How a whole lot larger do you need to drill a hole in a wood pole?
1/sixteen" bigger (Example three/four" bolt = 13/sixteen" Hole)
How often do you want to electrically test live line tools?
Every 2 years (100,000 volts for fiber glass, seventy five,000 volts for wooden.)
At what length do transformers begin being subtractive no longer additive?
200 KVA and up or 8660 Volts.
Delta Secondary Voltages?
Delta doubles (Phase to segment is usually 2 x Phase to neutral.)
