1 3301In hydel power plants, L.A's, S.C's are placed inside the control panel boards. what is the purpose? [already the total body was earthed to ground.]
1438hi friends if you have any 400KV Substation Erection and installations Drgs please send to me.My email id:kandi.suresh441@gmail.com
2387if an insulated power and control cables of a running gas diesel gensets laid direct in an open trench i.e, trench bed is not rcc of a power house in which rain water, spillage water alwas exists and all power control cables remains submerged even when gas gensets of 480 kw each runningin on load. These power &control cables runs from power house to switchgear room through these trenches in which water remains most of the time. pl explain its merit & de-merit
1401if a 3phase 100kva distribution transformer , 400 v,50 hz, 4-wire system is loaded at 160 k.w mostly 1-phase Lighting & Airconditioning split a.c load what will be the net effect on the power system in terms of voltage, powerfactor, current , efficiency of xformer
