Answer / mahavir jagdev

In rotating machines the speed will increse along with the magnetic and eddy current losses. In a tranformer the losses will increase.

Answer / rajeev

obviously the speed of motor will increase along with that
there is a determintal effects in load like tube light,bulb
as blinking will seen

Answer / balajisakthivel

In INDIAN govt will provide 50HZ frequency for AC
supplies.All the equipment are manufacture for that
frequency only.So,frequency can't exceed.If it is exceed the
load will be damaged.

Answer / master ramunni raja.v

in America they are used 60 Hz frequency. If we use above
50Hz The current flow will b increased. So all the Equipment
works faster then 50Hz operation speed. So current flow
increased.

Answer / raghav govind

First we have know frequency ...you know the number of cycle per second ....that is the current flow denotes per second ...and also to know wavelenth ..the distance between completion of one cycle (frequency) ..since ...we are going to how much cycle can complete in a desired voltage...but in india the cycle per second was fixed....hence if we take 100w load takes...with the desired voltage 230...therefore the load will taking amps as in name plate details...if we taken. 100W load in america...with same current taking with. 60 Hz frequency .....here the voltage should be changed to as 110 v ac...therefore frequency increase above 50hz ...the voltage definitely going to decrease ...as it fix one voltage is possible...

If I have a LT panel 3ph, 415V, 50Hz which demand load-600kw, how we can calculate its body earth strip size.

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.
