Flashcards in Test 4 Deck (18)
What is a main line?
A distribution line composed of either 3 phases and a neutral or just 3 phases.
Lines going directly to customers fed from the main line.
THREE phase line with a NEUTRAL
The high voltage portion of a distribution line.
Is low voltage (120-480) and runs from PADMOUNT TO PEDESTAL
Also low voltage like secondary but run from pole to CUSTOMER.
Acceptable voltage range?
Phase to neutral?
7200 x 1.76
The majority of distribution poles are?
Underground is how many times more expensive than overhead?
What material are insulators made of?
Porcelain or polymer.
Pole mounted transformer?
A key element used to reduce the voltage to a level that can be used by customers.
Designed to open all three phases but not break load?
Designed to break fault duty.
Used to connect inductive reactants?
What contains a normal opener?
Connected together to form a low voltage grid network?
Network grid design.
