  • Abstract
    PROTECTION of rotating a-c machines against traveling wave voltages divides itself into 2 problems: protection of insulation to ground against impulse overvoltages and protection of the turn insulation against steep wave fronts. The impulse insulation strength of the machine to ground is assumed equal to approximately 2 times the terminal-to-terminal crest voltage (2.12E). The turn insulation strength is given in curve form and varies with machine kva and speed.
