Cable tray of Generator High voltage 11KV cable is not connected to Earth..

Rohit Sharma

WE have some generators which are producing 11KV voltage. 3 Phase cables coming from Generator are passing through the cable tray, so this cable tray body is not connected to earth. Pl see the attached picture for better understanding. 

Is there any risk to keep this tray floating or need to connect to earth. 

Kindly share your valuable comments.

    The cable tray should be earthed in one position only if it is steel/iron .  The problem is that the high amperage LV currents will induce a voltage into the iron tray which must be balanced out by the other 2 phases assuming you have 3 phases which should ideally be bundled..
