Estimating the remaining service life of asphalt-mica stator insulation

Synchronous generators were manufactured with asphalt bonded, mica flake insulation from 1917 to the 1950s. There is a large fleet, perhaps two thousand, of these machines still in service today. This paper presents the results of a well documented series of field tests, many to failure, on 20 aspha...
