Classification: CPC G | IPC G  H

Claim 7:
8. The insulation monitoring device of claim 7, wherein the control unit is configured to:
perform a primary tuning process according to a preset first time multiple,
perform a secondary tuning process for determining a sampling interval of a sampling period for calculating an average voltage according to a second time multiple different from the first time multiple when the difference between the first average voltage and the second average voltage is equal to or less than a preset first error range according to a result of the primary tuning, and
detect the second average voltage as a steady-state voltage according to whether the predetermined time has elapsed from a starting time point of the second tuning when the difference between the first average voltage and the second average voltage is equal to or less than a preset steady-state voltage error according to a result of the secondary tuning.
