    several Maintenance guys missed this

    Went to check why the customer had no heat to certain rooms in their house. After figuring that out. They asked me to see why they kept blowing lightbulbs everyday. Found this result.

    If you are trying to make a point, you need more description. I see two pics of a meter with voltage values displayed.

    Not enough info.

    Yikes, 120V leg reads 140+ and line to line is above 280? Light bulbs are not very happy at that voltage...

    memory in meter
    One way to outthink people is to make them think you think. They'll think you're not really thinking what you're trying to get them to think you think...........

    What I'm saying is there there is insufficient information about the testing, or even a hypothesis of the meaning of the results.

    We are left to assume what the display is trying to tell us.

    Are those voltages line to line? Line to neutral? Line to ECG?

    Who knows?

    The OP knows, but as of yet, that information has not been clearly shared.

    Yep. I am not the only one that over thinks things. The first one is a reading from a light fixture. The second one is from across the legs in the meter base

    Time to call the utility. Looks like a tap issue.

    transformer issue. Did call the utility. After I pulled the meter at a house a few doors down and got the same readings. Maintenance kept saying it was that the tenant was using cheap light bulbs lol You think the neighboorhood would of noticed problems and some one would of called.?

    The box type transformers use taps inside to select voltage ranges for the outputs. That is the "tap issue."

    The voltage is very high in the pictures.

    Did you find that throughout the house?

    I saw this once on a service call. If their "no heat" problem was attributed to failure due to that excessive line voltage, inform the customer to contact the electric company immediately. They will probably pay for damages done - and therefore pay for the repair.

    I personaly contacted the utility company. I do not trust many homeowners or tenants to contact the utility in such a case.
    Timebuilder the utilty ended up just replacing the transformer.

    I am still shocked that no other houses called in with problems. I called the utility and they had a faultsmen out in about 20 minutes
