Is there any calculations method to determine the span length? Would it be same calculation as per IEEE 605? How to determine span length the bus going up using vertical wall( please see attached photo).
I would appreciate if anyone could give some advise.
I have to design 34.5 kv rigid bus system which would be supported by underhung insulator ( insulator would be mounted at ceiling)and there would be AL pipe bus at other end of the insulator. I am wondering to calculate span length it would be same calculation as per IEEE 605? Since it would be...
Could a grounded wye 1phase station service transformer (4.16GRDY/2.4KV-240/120V) be connected L-N on high impedance grounding (HRG- 160 ohm, 15amps)system? If not then could you please explain why? During a ground fault what would be the value of line TO N voltage across the Station service?
I have power transformer( 25MVA, Delta/wye, 138kv/4.16kv)and the Xo is connected with 160ohm , 15A for 10 sec NGR. I have metering PT ( 3 single phase units, two bushings N.S.V 15kv, 110 kv bil, H1-H2-2.4kv, SEC. 120V ratio 20:1)which I am planing to connect L-N. In such case which type of...
Hello,
I have to calculate allowable span length where there is 3 spans. From left, two spans consist of insulator with Slide, slide and fixed connector. The next right span has disconnect switch with expansion connector.The bus is 3.5" sch 40 AL with insulator TR287. I went through IEEE 605...
