On-Line Partial Discharge
On-Line Partial Discharge

PDSurveillantTM: PD-MIMS

PD-MIMS (Motor Insulation Monitoring System) detects partial discharge (PD) coming from the inside of high voltage motors and generators, the PD signal coupling in each phase (A, B, C Phase) using capacitor coupler. This system executes the surveillance and canalization of insulation condition of the high voltage motors and generators through QM/NQN analysis.

PD-MIMS provides user friendly software which allows access to the measured data from a remote office using RS-422/485 and LAN.

PD-MIMS also provides software which is designed to analyze, manage and interpret measured data and can be set to report daily, weekly or monthly.

  • PD-MIMS continually monitors and stores test results.
  • Detects abnormal conditions in motors and generators giving early warning when action is needed to prevent failure.
  • Reduces maintenance costs and operational expenses.
  • This test device continuously scans between 200kHZ – 300MHz.
