WHEN A INDUCTIVE LOAD IS OPENED IT CREATES VERY HIGH BACK
WHICH AT TIME CAUSE THE FAILURE OF COMPONENTS.BY PROVIDING
FREE WHEELING DIODE BACK EMF WILL NOT BE MUCH AS THE
CURRENT CIRCUITWILL COMPLETE THRU INDUCTOR &DIODE &THE
VOLTAGE WILL NOT BE THERE IN OTHER CIRCUITS

why Induction Generators are not "Black start" ? and apart from WTGs where this types of generator are generally used?

In our factory so many iron pillors are exists for supporting the shed/Hangar. If do more no of earthings at one piller instead of doing more earth pits in many locations and running earth strip around the hanger, I can save the money. Please suggest this method is acceptable as per Is specifications though the Earth resitance of the farthest piller is with in the limits as per IS specifications.
