Earth fault monitoring system KDZ-3

The KDZ-3 device allows for continuous monitoring of insulation's condition of unearthed DC power supply circuits, and in case of its deterioration, for selective location of earth fault or shorting between circuits of different sections. The digital KDZ-3 monitoring system 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.

Apart from having standard signaling functions KDZ-3 is also an event recorder; furthermore, it enables relaying data to a station monitoring system. Software enables remote communication with the device, remote control and monitoring its condition, reading of recorded data, and potential change of settings.
