Cylindrical Generator usually 2 or 4 poles synchronous machine also called round rotor generator. Because of its high speed (1800 or 3600 RPM) the rotor diameter is limited to a maximum of about 1.5 m. End Windings also referred to as the overhang. It is the section of the stator windings extending outside the stator slot.

Generator earthing and stator earth fault protection
Another method for protecting the entire stator winding of a generator is to deploy signal injection equipment to inject a low frequency voltage between the stator star point and earth. An earth fault at any winding location will result in the flow of a measurable injection current to cause protection
Insulation Resistance and Polarization Index Testing of
In a winding system most OEM’s recommend a PI value of 1.25 or higher on a rotor winding and 2.0 or better on a stator winding. The reason for the difference lies in the fact that most generator rotors are an open insulation system with naked conductors in the end winding potion and thus it is expected to tolerate lower insulation
