Sampling 11kva lines

Dear student,

first, 11 kV or 11kva ?

please find out a power system book and read it. It covers all topics how to design with calculations.

Dear Sir,

Its 11KV lines which is input to the transmission transformers, Thanks for the information, if you can send some link I will go thro it.
Or if you have ready circuit, It will help me a lot.

Thank you much

11kV is not considered as transmission lines...It is primary distribution.....what is your question? sampling of 11kV lines??...cut a piece from the line for sample...be careful about smoke from your body

Your 11kV distribution lines can be "sampled" using voltage (instrument) transformers with primary rated for your 11kV lines and secondary at 115V. The secondary goes to a meter or a voltage relay, that can indicate whether the circuit is above or below the minimum acceptable level.
