Section 8 Handle disturbancesAbout this chapterThis chapter describes disturbance detection and handling. This includes resettingLED alarms, triggering disturbance reports and the viewing of several fault indicators.8.1 Identify a disturbanceA disturbance record can be generated manually by using the Manual Trigfunctionality in the HMI menu. Other disturbance records are generatedautomatically in the system dependant on the settings made. Disturbance reportsgenerate a disturbance sequence number and are time tagged. The fault locationand fault loop are among the data generated in a fault record. Under each faultreport there are five categories of information available. These are described in thesections that follow.8.2 View disturbance record details8.2.1 View general informationBy choosing General information after selecting a disturbance record in the list ofdisturbance records the screen generated displays information about thedisturbance such as its sequence number, time of occurrence, trig-signal, faultlocation and fault loop.
