If any one of them is detected damaged or having error, this device will be blocked and issues a relevant alarm signal. The LED indicator “HEALTHY” will be extinguished.3.2.2 Setting SupervisionThe settings are checked to ensure them to be correct and not to be modified. If the settings are checked to have any error in them, the alarm signal [Alm_Setting] will be issued and this equipment will be blocked at the same time. The LED indicator “HEALTHY” will be extinguished.3.2.3 CT Failure SupervisionThe main purpose of the current transformer (CT) circuit failure supervision function is to detect faults in the secondary circuits of CT and avoid influence on the operation of corresponding protection functions.
