METHOD FOR CHECKING TURN-TO-TURN INSULATION OF LARGE ELECTRICAL MACHINES

摘要

FIELD: instrumentation engineering; turn-to-turn insulation tests. SUBSTANCE: device implementing this method has power supply 1, pulse voltage source 2, split ferrite core 3 with windings, damped wave frequency metering device 4 oscillatory-process damping degree metering device 5. EFFECT: improved validity of check. 1 dwg
