Hello, I am just preparing my self for a university interview and struck on the 11kv ring main unit system network. I just know that ring main unit has total three breakers, fuses and use to supply a power to any load/ building without any interrupt. But i am not be able to visualize the connections, either Ring main unit getting power from two different power sources? or there is always one feeder in complete ring circuit??? I would be highly thanks full of you help me.
i am working in automation feild my question is that how to find the KVA of transformer.
what is the voltage and ampere rating of all range of HT conductor?
Whether we used insulated line for 33KV supply. what we called it.
Load transfer in 11kv double busbar switchgear - operation.
How is the connection of the tap changer on the HV side been made?
why incomer bay is required before transformer bay if there are more than 1 nos. of transformer bay.
what is static electricity and how it generates?
present we are having 0.8pf but I want increase it up to 0.99 so what is the formula for it and how can i calculate?
what are the principles of a booster converter?
When motor stater and roter air gap do big then what will moter.
How much minimum insulation required between 11kv/3.3kv transformer windings?
what is range ACB
