Regular

Many alternating-current rotating electric machines are designed to have multiturn form-wound stator coils. In these cases, the winding has two separate but interrelated insulating barriers: one (turn insulation) between the various turns and the second (ground insulation) between the turns and ground. Failure of either of these barriers will prematurely terminate the service life of the machine. A test level, twice rated voltage plus 1 kV, for the ground insulation has been in existence for many years. This guide suggests methods and test levels for the turn insulation.

522-2004 - IEEE Guide for Testing Turn Insulation of Form-Wound Stator Coils for Alternating-Current Electric Machines
January 1, 2004 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Suggestions are made for testing the dielectric strength of the insulation separating the various turns from each other within multiturn 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 (270 hp to 13...
