Analysis of Insulation Diagnostic Test for High Voltage motor (II)

고압전동기 절연진단 해석 (II)

The insulation diagnostic tests was performed at local thermal power plants high voltage motor. The insulation diagnostic tests include measurements of insulation resistance, polarization index, AC current, $tan{\delta}$, partial discharges. This paper describes Insulation characteristics for high voltage motor which located by inside and outside.
