america 60hz electric supply is used; but india it is 50hz;
why? and if we use 60 hz supply what changeg has to be done
or all the equipment has to be thrown which has rating of
50hz frequincy
Answer / venkatgopal
because in america the machinces are constructed with 60 hz
frequency and another reason is america is ecnomically
better than the india so when freqency is high the power
transmisson is at high rate and loosses also high.when they
are economically good so for redusing the looses they are
using good insulaters

Please clarify, 1. Is it required to lay two runs of GI wire along with Armoured LT cable if it is laid between one big mains (63Amps TPN SDF) to small main (32A TPN SDF) with proper glanding termination? 2. If the armoured cable with proper glanding is laid from DB to CNC machine, is it required to run two runs of body earthing to the Machine from DB? 3.If the armoured cable with proper glanding is laid from Substation to Hangar, distance is approx. 100 mtrs, is it required to do earthing at shop area though the primary termination at substation is earthed through gland.
