JUNIOR ENGINEERS ELECTRICAL EXAMINATION, 2015Paper-I (i) General Intelligence & Reasoning: The Syllabus for General Intelligence would include uestions of both !erbal and non-!erbal type" The test #ay include uestions on analogies$ si#ilarities$ differences$ space !isuali%ation$ proble# sol!ing$ analysis$ &udge#ent$ decision #a'ing$ !isual #e#ory$ discri#ination$ obser!ation$ relationship concepts$ arith#etical reasoning$ !erbal and figure classification$ arith#etical nu#ber series etc" The test will also include uestions designed to test the candidate(s abilities to deal with abstractideas and sy#bols and their relationships$ arith#etical co#putationsand other analytical functions" (ii) General )wareness: *uestions will be ai#ed at testing the candidate(s general awareness of the en!iron#ent around hi#+her and its application to society" *uestions will also be designed to test 'nowledge of current e!ents and of such #atters of e!eryday obser!ations and e,perience in their scientific aspect as #ay be e,pected of any educated person" The test will also include uestions relating to India and its neighbouring countries especially pertaining to -istory$ .ulture$ Geography$ /cono#ic Scene$ General Polity and Scientific Research$ etc" These uestions will be such that they do not reuire a special study of any discipline"(iii) General /ngineering (/lectrical)/lectrical /ngineering 0asic concepts$ .ircuit law$ 1agnetic .ircuit$ ). 2unda#entals$ 1easure#ent and 1easuring instru#ents$ /lectrical 1achines$ 2ractional 3ilowatt 1otors and single phase induction 1otors$ Synchronous 1achines$ Generation$ Trans#ission and 4istribution$ /sti#ation and .osting$ 5tili%ation and /lectrical /nergy$ 0asic /lectronicsPaper II(/lectrical /ngineering): 0asic concepts : .oncepts of resistance$ inductance$ capacitance$ and !arious factors affecting the#" .oncepts of current$ !oltage$ power$ energy and theirunits" .ircuit law : 3irchhoff(s law$ Si#ple .ircuit solution using networ' theore#s" 1agnetic .ircuit : .oncepts of flu,$ ##f$ reluctance$ 4ifferent 'inds of #agnetic #aterials$ 1agnetic calculations for conductors of different configuration e"g" straight$ circular$ solenoidal$ etc" /lectro#agnetic induction$ self and #utual induction" ). 2unda#entals: Instantaneous$ pea'$ R"1"S" and a!erage !alues of alternating wa!es$ Representation of sinusoidal wa!e for#$ si#ple series and parallel )..ircuits consisting of R"6" and .$ Resonance$ Tan' .ircuit" Poly Phase syste# 7 star and delta connection$ 8 phase power$ 4. and sinusoidal response of R-6and R-. circuit" 1easure#ent and #easuring instru#ents: 1easure#ent of power (9 phase and 8 phase$ both acti!e and re-acti!e) and energy$ : watt#eter #ethod of 8 phase power #easure#ent" 1easure#ent of freuency and phase angle" )##eter and !olt#eter (both #o!ing oil and #o!ing iron type)$ e,tension of range watt#eter$ 1ulti#eters$ 1egger$ /nergy #eter ). 0ridges" 5se of .R;$ Signal Generator$ .T$ PT and their uses" /arth 2ault detection" /lectrical 1achines : (a) 4"." 1achine 7 .onstruction$ 0asic Principles of 4"." #otors and generators$ their characteristics$ speed control and starting of 4"." 1otors" 1ethod of bra'ing #otor$ 6osses and efficiency of 4"." 1achines" (b) 9 phase and 8 phase transfor#ers 7 .onstruction$ Principles of operation$ eui!alent circuit$ !oltage regulation$ ;"." and S"."
