INSULATION CHECK SENSOR FOR ELECTRICAL-MACHINE LAMINATED-CORE STAMPINGS Russian patent published in 2003 - IPC

Abstract RU 2206951 C1

FIELD: electrical engineering; insulation diagnosing and inspection in ac machine stator core stampings. SUBSTANCE: device intended to check insulation between laminated-core stampings in ac machines irrespective of ground fault location is, essentially, sensor that has ferromagnetic core and sensing elements. Novelty is that part of or all sensing elements are disposed on scanning surfaces of core. EFFECT: facilitated procedure; enhanced reliability of ground fault detection. 1 cl, 4 dwg
