Summary
Hydro generators are exposed to contamination from the surroundings through its cooling system. Carbon dust from slipring brushes, oil leakage from bearings, dust from brakes and dust from outside are typical sources for contamination. This causes reduced insulation resistance and can lead to electric failure on the generators.
