Scope

The purpose of this guide is to make suggestions on testing the dielectric strength of the insulation separating the various turns from each other within multitum form-wound coils to determine their acceptability. Typical ratings of machines employing such coils normally lie within the range of 200 kW to 100 MW. Test voltage levels described herein do not evaluate the ability of the turn insulation to withstand abnormal voltage surges@ as contrast~d to surges associated with normal operation. These suggestions apply to: Individual stator coils after manufacture. Coils in completely wound stators of original manufacture. Coils and windings for rewinds of used machinery. Windings of machines ii;i service to determine their suitability for further service (preventive-maintenance testing
