Is it necessary to have UV coil tripping facility to the grid side of a switch board, in which generator supply is also fed through a change overing device?
There were many accidents happened due to failure of the change overing mechanism, and thereby back feeding of the stand by supply to the grid line. With most of the standard AMF circuits, there will be under voltage tripping provision. But, in many electronic change overs, there may not be adequate protection to prevent this danger. Where as, with conventional change over switches since no automatic change overing to happen, may not be insisted to add uv tripping facility. But, it is your discretion, so as to ensure the protection.
