Insulation measurements

The device monitors the insulation of ungrounded power system.

The device (IM400N) :

  • measures and displays:

    • the insulation resistance R (Ω) continuously,

    • the insulation capacitance C, which is the leakage capacitance of the distribution system to ground (μF),

  • calculates and displays the impedance Zc (kΩ) associated with C.

The device (IM400THRN) measures and displays the insulation resistance R (Ω) continuously.

To view these values, navigate to Menu > Monitoring.
