11 Specification for SF Monitoring: Features of an Gas Density Monitoring System: he SF density (temperature compensated pressure) as well as the leakage rate are accessible via communication protocol IEC 0 (or via a web-based user interface) he period until an critical gas filling level is reached will be calculated and displayed Measured data is stored over several years and can be simply exported for further analysis he system meets state of the art cyber security standards, in particular any access is password protected and provides several user groups he system offers one central communication interface for the complete substation (via Ethernet) he system has an internal monitoring feature which identifies system failures and triggers alarms Algorithm calculates the leakage trend for all connected SF gas compartments. Visualization: An MI displays can be installed near to the GIS or in an dedicated control room he actual value and leakage rate can be displayed or transferred to a central SCADA System via IEC 0 for further processing and alarm handling. Easy navigation through the measurement data, alarm list and event history is possible Status s will signalize device failures and gas alarms. Siemens AG 0 Page anuary 0
