Which statement regarding moisture absorbed in the windings or condensed on the surface of electrical machinery insulation is true?
Moisture is good for long term preserving since most insulation is organic and contains some amount of moisture anyway.
Moisture lowers the insulation value and is a common cause of fault grounds in idle machines.
Moisture will enhance insulation resistance only if it is fresh water and contains no salt.
Moisture reduces the amount of current supplied or drawn by the machine so horsepower is limited.
