Re: Why we call cable rating in SQ.mm.If it is 240 SQ.mm how much the diameter possible?is there any calculation ?
# 1
it is bcoj the cable diameter is decided wby the amount of
current it hav to bear.....thus the conductor is choosen
according to its dia size...

# 2
When we say that cable rating is 240 sq mm the user knows
that the area of the conductor is 240 square mm. Hence user
can determine the amount of current that cable can carry.
Calculate the dimension of circle which has a area of 240

  Question Asked @ Answers Other Electrical Engineering Interview Questions we all know that in transformer, voltage and current are inversely related i.e. Vp/Vs= Is/Ip....so in standard CT..we have a ratio of 200/5...that means our voltage should increase by ratio of 40..althoug that is not the case...because that requires high insulation level.and pratically not feasible......can anybody clarify my ques.......thanx 2 Between rotating armature type and rotating field type arrangements which one is adopted for large rated alternators and DC generators.Why there is difference in the choice? 1 Which type of drive is advantageous AC or DC and why? 5 What is the direction of rotation of blades in a table fan and in a ceiling fan ? Power-Grid 11 for testing busbar (33kv) hi-pot .whether we can apply DC r not.and what is the test volt for that .explain 4 why grid frequency varry time to time? 2 What is TR of AC? 7 Disadvantage of leading power factor 3 line vltage of three phase distribution transformer is 433v and phase voltage is 250v,but we required 230v for domestic distribution,then how we reduce phase voltage of transformer 5 What is Form factor? NTPC 2 star delta connection used in reduce the starting current at 3 times . how its reduce the current please explian . HP 7 Can anyone tell me how a 12v battery is transformed to 20,000v at the spark plug 6 For more Electrical Engineering Interview Questions Click Here
