WebbDistance protection is used for the protection of extra high voltage transmission and sub-transmission The major advantage of distance protection is that it would do the fault coverage of the circuit independent of the variations in the source voltage It would provide primary and backup protection WebbDistance protection, in its basic form, is a non-unit system of protection offering considerable economic and technical advantages. Unlike phase and neutral overcurrent protection, the key advantage of distance protection is that its fault coverage of the protected circuit is virtually independent of source impedance variations. can hitting curb damage wheel bearing https://numbermoja.com
