    what does this phrase mean "a transformer with 5% impedance'

    for a simple understanding, this is percentage of voltage. The rated current will be obtained when the this much % voltage applies on the primary. Basically for the fault current calculations, this will be useful.

    GTG - Overfrequency protection

    A small correction As long as your turbine control is perfect, this electrical protection is not required, how ever the turbine shall have over speed protection at 105% to 100% based on the manufacturer's recommendation.

    even harmonics

    Unless there is an abnormality in eithr the source or the load, the even harmonics will not be generated. In general only 3rd harmonics will be generated with such type of rectifiers(not wiht half wave). The even harmonics will be cancelled with the load itself. concentrate on nature of...

    Generator Rotor Earth Fault Protection

    Why in power station, always the Medium voltage change over is from station to unit or station to station. Why not the practice of change over from unit to unit if there are multiple generator blocks are available. Is there any technical reason behind this?
