摘要
An apparatus to detect a breakdown in the insulation of a through-bolt in a laminated generator core is provided. The apparatus provides a ground detection circuit to generate and sense a signal in response to a ground that develops as a result of a breakdown in through-bolt insulation. Preferably, the circuit includes a signal source that generates a signal in response to insulation breakdown and a signal sensor to sense the signal so generated. The apparatus, moreover, can identify which among a plurality of through-bolts has experienced an insulation breakdown. Methods also are provided for detecting a breakdown in through-bolt insulation and identifying which among a plurality of through-bolts has experienced a breakdown in insulation.
