What else can I help you with?
How many bushing wells are there for one high voltage input of the Primary Distribution Center?
3
What do you use to install loadbreak elbows on the input or output bushing wells of the primary distribution center?
grip-all clamp stick
When testing for voltage on an energized primary distribution center what form is used to document any discrepancy that is found?
AFTO Form 244
To perform a complete inspection of an energized Primary Distribution Center you should remove the all of the fastened access panels so you can look inside?
false
Energized electrons at the primary electron acceptor flow to where?
an electron transport chain.
What is the primary hazard associated with a fire involving energized electrical equipment?
explosion
The load interrupter switches of the primary switching center can be operated when the circuit is energized?
true
What is the difference between primary electrical distribution and secondary distribution?
Primary electrical distribution carries medium voltage power to distribution transformers near the customers. Secondary electrical distribution transfers the power from the transformer to the households.
What is created when you lay the primary cable between the power source and the primary distribution center or primary switching center?
a primary power buss
What happens when the primary winding is energized and the secondary winding is open circuited?
A voltage appears between the terminal points of the secondary winding
What is Primary distribution overhead cost?
Primary distribution overhead cost is also called Departmentalization of overheads. It involves apportionment and allocation of overhead costs in the service and production departments.
120v240v what does it mean?
In North America it is the standard electrical service connection voltages. Usually a pole mounted transformer supplies this voltage. In newer subdivisions the trend is turning to pad mount transformers which allows the primary voltage lines to be underground. Looking at the transformer you will see three insulator bushings. The first and third bushing are the working voltage (house connections 240 volts). The middle bushing is a center tap. This gives a voltage of (bushing left to center 120 volts) and (bushing center to bushing right 120 volts) These are the the three wires that come into a house for its 120/240 volt service.
