bogey, I have been trying to find data on EMF for our cable for a while without success. The tech data like inductance etc does not help much. The field level and gradient is also function of the cable configuration, how is hung in relation to the other cables and towers. The example we looked shows lowered levels of EMF due, in my personal opinion, different cable configuration and different type of towers. Often the electromagnetic field is a problem by itself. What I mean by that that regardless of envoiromental impact of EMF the field itself creates problems with line stability and also with isolators, these glass or ceramic devices on which cable is suspended from. Therefore often two parallel cables are used or even bank of cables creating a circle by means of ring. Also you may observe the ring around the end of isolator to decrease field gradient, it means to make it more even so overvoltages will not short to ground or damage the isolator.
Should have asked me this stuff 30 years ago when I was getting degree in the field of high voltage transmission, where you have been all these years - LOL!
