L1-G short circuit on line Klm-WOL 536
The short circuit is located at 4.77 km [Mast356;Mast355] +/- 1.27 km from station Wolmirstedt
Line Klm-Wol 536 is surely faulty
L1-G short circuit on line Eu-Wd 208
The short circuit is located at 62.35 km [Mast181;Mast182] +/- 3.36 km from station Eula
Line EU-WD is surely faulty

- 12. Power Grid Monitoring 12 1. Real Time Supervision • Goal: quickly & reliably identify faulty scenario Deploy Emergency crew in a targeted small area Reduce outage time 2. Post-mortem Analysis • Goal: improve efficiency and system quality Fault analysis & characterization – type, duration, fault impedance, distance Voltage Quality and Stability – power quality Asset mulfunctioning with root cause analysis Data archival for statistical analysis Frequency Stability - Wide Area Monitoring 1 Platform : 2 Types of Monitoring, 2 Systems…
- 13. Automated Fault Analysis 13 Use of oscillographic records (COMTRADE format) Time saving: automatic collection and classification of various event-related following any disturbance. Fast indication (within a few minutes) of healthy / faulty lines Fast indication of accurate and reliable fault location to optimize crew interventions: Presentation of the sequence of events, measurements and key performance indicators to facilitate and speed up the post mortem analysis Providing of fault statistics regarding lines, transformers, breakers and protection devices. Main Benefits Boasts productivity of both dispatching crews and post-mortem analysts
