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 the function of transformer 33kv?
A '33-kV transformer' is a three-phase primary-distribution transformer, used in the UK's electricity system to step down the 33-kV primary-distribution voltage to the 11-kV secondary-distribution voltage -the lowest voltage used in the high-voltage distribution system. These transformers are categorised as 'power transformers', and are located in what are termed 'primary substations'.
Are number of turns on primary side and secondary side same in case of star star connections?
The number of primary and secondary turns, or turns ratio, determine the secondary voltage given a particular primary voltage. So, for instance, if the primary voltage is 480/277 wye, and the desired secondary voltage is 208/120 wye, the turns ratio would be 2.3:1. If the primary and secondary voltages are the same, then yes, the number of turns on primary and secondary would be the same. But if you're not converting delta to wye or vice-versa, why would you have a transformer with the same input and output voltage, other than an isolation transformer?
What is quad ring main unit in electrical distribution in particular with transformer?
Quad ring main unit (QRM) is used to connect 2 no. transformers at their high voltage side to the distribution system.
What are the output voltage and current of a transformer determined by?
The secondary (output) voltage is determined by the primary voltage and the turns ratio of the transformer. The secondary current is determined by the secondary voltage and the load resistance.
What size cable is used for the high voltage connections between the source primary distribution center and the secondary distribution centers?
#1/0 5-KV insulated aluminum cable
How is one secondary distribution center connected to another secondary distribution center?
high voltage cable with loadbreak elbows
How many high voltage outputs does a secondary distribution center have?
2
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.
Why transformar primary refers to secondary?
All transformers contain both primary and secondary coils. The primary will refer to the secondary when the voltage is to high. As voltage increases, it passes down the power to the secondary for efficient distribution of power.
When connecting low voltage cables to a Secondary Distribution Center where should you start?
At the bottom
What is the voltage phase shift between primary and secondary line voltages in star-delta transformer connection?
The voltage phase shift between primary and secondary connections in a transformer is 180 electrical degrees.
Is corona a bad thing to have around the high voltage connections of the Primary distribution Center?
yes it produceses ozone
Where will you find all of the controls and indicators needed to opeate the secondary distribution center?
in the low voltage compartment
What is the electrical function of the secondary distribution centre?
An electrical distribution centre is used to distribute circuits through out the building that it supplies. An electrical panel in your home is classified as an electrical distribution panel. The electrical distribution panels come in varying sizes and voltage ratings depending on what the building requirements are. Amperages for different loads are supplied through breakers that are part of the distribution panel.

Why does a phase in secondary side in distribution transformer give low voltage?
transformer is busted; if input voltage is normal you have short circuit or open circuit somewhere
