Eerie power hit...

Posted: Wed Dec 25, 2013 9:22 pm
So I am sitting in my living room, watching TV, all the lights in the place did a quick flash off and back on. Very quick flash. About 5 minutes later, start getting transmitter alarms like we took a power hit at the transmitter. The odd thing is, I live in a large metro area and the transmitter is 12 miles, 6 cities, and several thousand people away from me. The scanner is dead quiet, so I don't know what this was. Never seen a large scale "flash" before.

Heard from my friend who is the transmitter engineer at WHDH, they took a hit at both their transmitters (one in Needham, one in Newton) and at their studios in Downtown Boston.

Is it possible a large transmission line failed somewhere up north (Maine?) & the glitch happened when they put it back online? Maybe some unsynchronized generation?

Just wild-guessing & showing my ignorance towards any electrical circuits beyond 10,000 volts...

A main transmission line in a substation in Allston came "loose," which caused a huge bright flash and power-line glitches all the way to Rhode Island. ... index.html

One of our sites threw a "plate voltage over limit" alarm, but by the time our DOE dialed in everything was normal.
