As regulars will be aware, I'm a relative novice when it comes down to REIN and it's many guises, but have been in attendance on quite a few jobs, and been 100% succesful in the 2 issued to me since completing my training (big whoopee eh ??
).
So, on the back of that, Walter ..... no, I've never 'earthed' the "Catenary" wires as you mentioned. By catenary, do you mean the steel strengtheners that are in the dropwire 10/12/14
Again, from my limited experience, the higher percentage of REIN faults I've been involved in has seen the source begin at the EU's premises and 'track' back up the dropwire to the DP, and then (depending on the strength of the interference), into some or all of the other dropwires fed from that DP. In a recent case, it actually then went down the UG cable feeding the DP, and into another UG cable running parrallel to it in an underground box. This caused another DP and it's EU's to be affected.
I identified the source of the REIN, informed and proved it to the occupant of the house it was emmiting from, and then informed the REIN team. 'We' (Openreach) have no powers at all thus far to make the occupant switch off, or remove the offending item. 'We' feed back the information to the SP of where the REIN is coming from and it is down to
them to liase with the occupant and try and reach some kind of compromise.
B*Cat is also correct (and covered by myself in another thread months ago) in that any change to 'flying wires' whether they be multi-core or otherwise, would need stringent load bearing tests/aerodynamic effects. We have 'certain' maximum distances we can erect different types of OH cables, and any further weight gain given to those cables may drastically affect this distance. I'm not sure how many poles we have nationwide, but the costing would be astronomical if major parameter changes were implemented.
We know REIN is more prevalent of late than in years gone by, due to much higher frequencies susceptible to noise, being pumped down our cables. Also, the comment below about access to REIN testing equipment
was correct, but in-roads are being made to purchase more 444b testers. I can verify this to be fact, as I have filled in the neccessaries to get one myself just a few weeks ago and our Level 2 manager agreed to the price of it.
I reiterate, REIN is a problem, but as yet not directly under the juradstiction of Openreach, as we perform the location of it as a 'Goodwill gesture' only . 'We' are however training lots more engineers in REIN fault-finding. HTH
