    GE ES-3 Watt hour meter

    I need to find a instruction manual for a GE ES-3 Watt hour meter. I had a thread on this earlier and got a connection diagram but I really need to know what the accuracy rating of the meter is.

    Generator issues

    I have a garbage burning generator that is having load fluctations. The plant has 3 generators, (2) 13.5MW units, and this 25MW unit. The twin 13.5MW units are stable, but the 25MW unit is constantly moving about 1 MW every minute. The 25MW unit swings even if the two 13.5MW units are...

    Transformer Core de-magnetization

    I have a GSU trasformer that I have someone testing and they did the testing out of order and did a winding resistance test first. Now the power factor readings a all messed up because the core is now magnetized. I know to de-magnetize it you need to use either DC current or voltage. We have...

    #rd Harmonics from Steam Turbine Generator

    I have a problem i am trying to resolve. I have acustomer that has a 3MW 6900V steam turbine generator that had the stator rewound about 4 months ago. Since the gen. was reinstalled they are getting nuetral overcurrent trips. In monitoring the nuetral current, I have discovered that not only...
