Earth fault measuring unit KDZ-3W

The portable KDZ-3W earth fault measuring unit is to be used in automation and protection circuits as an element monitoring condition of insulation in both DC and AC circuits. Furthermore, since it works with the KDZ-3C clamp it allows for precise localization of the area with deteriorating insulation. The KDZ-3W earth fault measuring unit is a device designed based on many years of experience in production and installation of switchgears, as well as state of the art trends and technical capabilities. The KDZ-3W is capable of signalling when defined alarm thresholds of earth fault resistance are exceeded.
