as it is most affected by arc resistance....
Ohm relay.......
reactance relay is used for distance protection of the transmission line....
MHO distance relays are used to protect andÊdetect faults and the location of faults on a transmission line. It detects faults by measuring and comparing phase angles through a phase comparator.
yes its used in transmission line.fuse normally used in peravitiu in all electrical systeam
Frequency modulation is not used for long distance transmission because it has the problem of limited band width.
distance relay..........
mho rerlay is used in long transmission lines

There are three types of transmission lines of India given follows ---- 1-long transmission line( which is used grid to power suppliers plant ) 2-medium transmission line ( which is used power supplier plant to the industry ) 3- short transmission line ( which is used transformer to the consumers )
MHO distance relays are used to protect andÊdetect faults and the location of faults on a transmission line. It detects faults by measuring and comparing phase angles through a phase comparator.
IR transmission type of transmission is used in television system .
yes its used in transmission line.fuse normally used in peravitiu in all electrical systeam
To (a) eliminate high voltage drops along the line, (b) to allow conductors of practical size to be used, and (c) to reduce line losses.
pg clamp is known for parallel groove clamp,especially used in transmission line to hold transmission conductors in parallel.
Buchholz Relay is a special type of relay and its only used in transformers, and the main use of this relay is transmission and distribution systemAnswerA Buchholz relay is used between a transformer and its expansion tank. So they are only used (1) where there is an expansion tank and, (2) in substations, where the associated protection relays can be installed.
coaxial cable and twisted pair cable. coaxial cable is the most widely used type of transmission line.
