Section 8 Handle disturbances
About this chapter
This chapter describes disturbance detection and handling. This includes resetting
LED alarms, triggering disturbance reports and the viewing of several fault indicators.
8.1 Identify a disturbance
A disturbance record can be generated manually by using the Manual Trig
functionality in the HMI menu. Other disturbance records are generated
automatically in the system dependant on the settings made. Disturbance reports
generate a disturbance sequence number and are time tagged. The fault location
and fault loop are among the data generated in a fault record. Under each fault
report there are five categories of information available. These are described in the
sections that follow.
