Hi,
I'm hoping an electrical engineer or experienced electrician can help here with a cause and plan of action.
I live in an apt on the ground floor of a 3 story building with 60 units. I'm being driven out of my mind by a loud noise that starts up at night when temperatures drop and/or load increases in our building. I've had to find another place to sleep.
The noise has been identified as coming from the electrical distribution box which is attached to a cement wall that runs up all three floors in my bedroom as a firewall. See pic below.
The building transformer is outside of our building and it checks out ok.
All equipment in the room below is the property and responsibility of the building owner.
Underground wires come into our building and into the box which is about 8 feet tall by about 10 feet wide. There are a couple of large power switches to switch off certain service areas. Cables split off to another electrical panels, and to two meter closets for meters for the individual units.
The noise is so bothersome but I haven't been able to get the building manager to investigate properly and fix. I can't sleep in my ground floor apt because of the noise/vibration being so loud and bothersome. An acoustic engineer confirmed the hum when it was not even bothersome.... Its in the 60-120-240 hz range. It's one time I hate having really good hearing range.
It's the left box... the whole thing is vibrating and making noise....
Really loud at times.... so loud I can hear it in my whole apartment above.
Also, there has been some flooding in the room.... but dry when this picture was taken....
Any ideas what would be causing the noise? I'm hoping I can present my findings here to the strata.
