I have been asked to look into problems at a residence. It is anolder house that has been split into two units. The tennants have been experiencing problems with voltage surges resulting in damaged electronics, TV's, computers, etc. they reported one tv billowing out lots of smoke when it was not even turned on. Also lights surge very bright for brief periods and go back down to normal. I checked all connections at the meter main including meter base (jaws) and all neuteral connections. Then I checked all connections at the sub panel serving the structure and although it is somewhat sloppy and I told the owner we need to replace it I can't find any corrosion or loose neuteral connections. The affected circuits are varied (not just one circuit). The utility company's transformet appears to serve two other homes and they report no problems. The utility co is to be out today to check connections at the weatherhead and install a recording volt meter to monitor incoming line. I'm somewhat stumped at the moment, the tennants report continued lighting surges. Any ideas?????
