Ungrounded, unearthed, “floating” or IT (Isolé-terré or Isolated Terra) are all terms used to describe power systems that have no intentional conductive connection to earth’s or chassis ground. The main advantage of the IT power system is that a single “short” will not disable its ability to continue delivering power.
What is an IMD? Insulation Monitoring Devices (IMDs) are essential components in electrical systems designed tocontinuously monitor the insulation resistance of electrical circuits.
DC and AC testing provide an equivalent level of breakdown detection, but the increased accuracy of DC leakage-currentdetection can reveal marginal insulation systems
