The system voltage is always specified in RMS value or we can say that we can measure only RMS value but actually the system is subjected to peak voltage. in case of 11 kv system if the LA is provided between line to neutral, which is normally the case is, the phase value will be 11kv/sqrt(3)= 6.35kv (the phase value. but the peak value for this phase voltage will be sqrt(2)*6.35kv = 8.98kv. hence the rating of LA will be 9kv

i am an maintenance engineer. one distribution board have 5 feeder. recently its ELR trips frequently, but it take some times after trip( 10min,20min..)but 3 feeder no load. two feeder only loaded. i checked one feeder IR value all values are above 50Mohm.but B phase to Earth is only 9Mohm.any problem about low value
