A friend of mine called me up the other night asking if I could take a look at his electrical problem. When I arrived they had a light on in the living room but it was very dim. He then showed me the light in the refrigerator and it was like looking into the sun. I unplugged the refrigerator and checked the votage at the outlet with a DVM and got ~170 volts. I then checked the power at the light and it was down to ~70 volts. So it appears that the 240 total is not being delivered properly to each leg of the bus. The power company came out and did not speak to anyone but they did recrimp the service to the house. There are at least 3 houses on the transformer but I am not sure if anyone else is experiencing any issues maybe its a bad transformer. I am guessing that it is a problem with the neutral on a circuit. If that is the case how do we determine the bad circuit. A little about the house it is older built in the 40"s service wiring is aluminum but all of the branch circuits are copper. The house is also using a common bus for ground and neutral and does not have a seperate ground. He did install a new clamp on the ground rod. Should we drive a new ground rod?
Thanks in advance for all you time, consideration and hopefully suggestions with this problem.
