Update on Glen Park RFI – National Grid Report

Posted on October 8, 2013 by Bob Beatty

Kurt, the RFI specialist from National Grid, contacted John King yesterday with a report on the RFI remediation work performed at Glen Park.

Hardware on 7 poles was replaced. One of those poles is located at end of the line near Glen Manor House; the rest are closer to the park itself.

After the “ivy pole” was cleared and a one of its insulators was replaced, a great deal of noise was still being generated in that vicinity. The source of that noise turned out to be the loose tie wires on the southern adjacent pole (see the club web site for pictures.) This is interesting, because: A.) Both Kurt and John had scanned that pole (the loose tie wire pole) with ultrasonic arc detectors without hearing much arc noise, and B.) that is the pole that we most strongly suspected when we walked the line with AM receivers and rubber duck antennas. Jack, N1JK, visited the site a second time after our initial Saturday RFI hunt session and came away convinced that the interference was coming from either that pole or the building fed from that pole.

Thanks to everyone who came out to help with this effort. The Glen Park site is now completely free from power line noise.

Glen Park “Blissfully Quiet” After National Grid Reworks Lines

Posted on October 4, 2013 by Admin Admin

National Grid has performed their RFI remediation work at Portsmouth’s Glen Park. John King visited the site today and has happily reported that the site is blissfully RFI quiet.

The line crew addressed multiple issues along the entire line, which runs from Glen Road, through Glen Park, and down to Elmhurst School. They didn’t miss a trick – note the attention they gave to the tie wires on the pole adjacent to the “ivy pole.” (Yes, loose tie wires can be a source of RFI.) They treated each pole on the line with the same attention to detail. This was a first class job by the National Grid folks.
