Title: Dielectric failure detecting apparatus
Inventor: YAMADA NAOYA
IPC: H02K11/00
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To easily detect layer short condition by extracting a current element generated by the layer-short condition from the measured current and outputting an alarm when the extracted current element is higher than the predetermined value. SOLUTION: When a zero-phase current Io is detected from a leak current detecting current transformer 43 to generate layer-short condition, a current element resulting from leak current Ir caused by the layer-short condition is also included in the zero-phase current Io. A measuring means 44 is composed of an element isolating means 44b1 for isolating the zero-phase current Io into a leak current Ir of the same phase element as the diagnostic voltage Vs and a current Ic as the element leading by π/2 and an extracting means 44b2 for extracting a leak current Ir of the same phase element isolated by the element isolating means 44b1.  Since tanδ between the part generating the layer-short condition and the third class grounding terminal E3 is deteriorated, when the leak current Ir increases and reaches the predetermined value, an alarm is generated from an alarm generating means 44a.
