whenever a large load in the network is removed suddenly
there will be a swell in voltage due to reduction of IZ
drop.Rarely lightning strokes are also responsible for
this.And whenever there is a fault in the line ,it will
cause dip in voltage momentarily.

1 “earthing” for bonding of equipment and circuits to common plant earth electrode potential, 2 “protective earthing (PE)” when this bonding is required for personal safety provisions 3 “grounding” for interference suppressing bonding of screens, sys-tems with ground level 4. low-impedance earthing ? 5.primary earthing system and secondary earthing system what is that? 6.earthing electrode or mesh net earthing electrode ? very confusing , simple but very informative help required ? i will be very very thankful to you guys.

there is an alternator 480 k.w, 400v,50hz, 4-wire running on load having leakage alternator body earthed current 38 A. is it within acceptable limit? if yes then give reference if no then how to bring within specified limit
We have drive feeding an output contactor for a 5000 hp motor @ 5kV application. The motor FLA is 629amps x 1.25% service factor = 786.25 amps The cable that we current have in place between the drive and the output contactor is 350kcmil- MV-105 (parallel cables). Per the NEC table 310.60 (C) (69). This show the cable ampacity is at 615 amps per cable for a rating of 1230 amps. We have derated the cable for the cable tray and the multiple cables application and our calculations show that after the correction factor factor we are at 922amps. 1230 amps x .75% correction factor factor = 922.5 amps. The customer is driving us to then use another safety factor of .25% off of the already derated cable. Can you please provide a longhand calculation for your solution on this application?

- two pumps must work with them at the same time but if the first pump start the second pump must delayed for some time to start also , with motor rated power = 90 KW and rated voltage = 380 V and rated power factor = 0.85 lag please draw the power and control circuit for it and determine all circuit components parameters that you use it
