    INTRODUCTION Product Overview The CB Watch 3 system (often abbreviated as CBW3 in this manual) is a monitoring system for high voltage circuit breakers. It monitors the following aspects: ▪ Operation timing ▪ SF6 gas leakage ▪ Arcing contact wear ▪...

    HUMAN MACHINE INTERFACE (HMI) Introduction The CB Watch 3 does not require the user to load a special software to connect to it and access the information it captures. The CBW3 has a built-in web server and an integrated Human Machine Interface (HMI) which is accessible from any web browser, The HMI lets the user configure the system, set alarms and visualise all the measured parameters, the alarm status and the curves/graphs recorded in memory.
