Answer Posted / suneetha
this is due to form factor
rms value of induced emf= form factor * average value
form factor is calculated as 1.11
so the ratings are usually expressed in multiples of 11

plz explain the auot-reclosing circuit in electrical engineeing
1)How much current can a 3-1/2 core 100 mm wire carry? 2)What are the special cables required for explosion proof wiring? 3)In case you do not have coal and salt for earthing, how can you achieve good temporary earthing? 4)One horse power single phase motor is more likely to get hot than a one horse power 3 phase motor. Is it true or false, if true why? 5)What are the different types of soft starters for large motors?please explain?

According to conduit size which size wiring & how many wires can we provide wires in conduit & how can we select conduit size accordingly?
If any HVDC line is going with positive & negative(the negative usually have return path of current with earthing electrode). Now the question is if this HVDC earthed electrode which is using as return path and earthed any nearby 400kv or 220kv AC substation equipments. which will be the impact of this on AC substation & its equipment, how severe may be this and what should be the minimum distance require between HVDC earthed electrode and AC substation equipments? It's really an high engineering level question...Dare to answer and increase your knowledge.

I have a drawing of a wound rotor induction motor for a crane. This crane motor has 5 forward speeds & 5 reverse speed implemented of course with different amount of resistance for each speed setting selected. What has got me scratching around is the fact that 8 of the 10 speed selections switch in uneven (unbalanced) amounts of resistances on each of the 3 connections to the motor's rotor.Can this be possible? I would have assumed this would produce unbalanced rotor currents and therefore vibration in the motor. I would greatly appreciate anyone's comments on this. Many thanks, Confused.
