Exams for apprentices
(OP)
I am afraid that as an instructor I was unable to answer with confidence the followig simple questions that appeared on a recent apprentice exam!!! Perhaps you might be able to ease my embarrassment!
1 The substation layout that requires a bus coupler cb is a;
(a) three switch
(b) sectionalised single bus-bar
(c) double busbar
(d) horseshoe busbar
2 The tension which overhead line conductors impose on terminal backstays is determined by the
(a) transverse load
(b) longtitudinal load
(c) ultimate tensile stress
(d) factor of safety
3 In the making of an impregnated pressure cable joint the core screens are;
(a) terminated at each end
(b) bonded to the lead sheath
(c) made off with flares and lead wire
(d) made continuous through the length
4 An expansion joint is used in some types of high voltage undergroun cables to counteract the effect of;
(a) excessive oil pressure
(b) load surges
(c) increased loading
(d) subsidence
Appreciate any effort.
