Why do we need Gas Density Monitoring? GIS Failure Reasons MiF Distribution of GIS CB MiF Distribution of other GIS parts Small SF6 leakage; 35,60% Gas Density Monitoring Small SF6 leakage; 63% Reference: CIGRE TB 510, Page 47, 2012! GIS failure leads to unplanned downtime, jeopardizing Network performance or industrial processes Assetguard GDM Assetguard GDM supports on avoiding unplanned downtime. Reference: CIGRE TB 513, Page 104, 2012 MiF= Minor Failure CB = Circuit Breaker Other GIS Parts = Busbar, Bushings, Surge arrester Page 6
Why do we need Gas Density Monitoring? The Greenhouse Effect The GIS insulation gas SF 6 is one of the worst greenhouse gases for our atmosphere. One kilogram of SF 6 equals 22,8 tons of CO2. The CO 2 equivalent of contained SF 6 in a typical GIS Bay (~80kg) equals 15 000 000 km driven with a regular car. = ~ 80 kg SF 6 ~ 1824 tons of CO2 (each car in Australia can drive one kilometer)! Different regulatory entities either reward saving of SF 6 gas or punish its loss. Assetguard GDM supports to safe the environment and fulfill the regulatory requirements. Page 7

Besides complying to superior EMC and environmental standards, every single device can connect up to 48 sensors providing a cost efficient channel per device ration. Page 12
Main Features for field devices 1 Assess Near Real Time Data Acquisition Alarming Based on Actual Measurements Gas Density Alarms generation based on the current measured value Advance Warning of SF6 Leaks (Predictions) The Assetguard GDM is able to take measurements every second and generate an alarm based on the actual measure. Furthermore, prediction dates can be determined before the alarms levels are achieved. Every second a new measure is taken Predictions for Stage 1 and Stage 2 Alarm levels Page 13

Support Services 3 Act Direct contact with Siemens Support Center Event Scheduler ISCM Alarm Support ISCM supports you on making the right decisions based on the available data. Asset Managers can easily plan maintenance activities and get support at any time. Maintenance Mode Page 21
Support Services 3 Act Event Scheduler Predictions are handled as future Events!! Maintenance Mode A calendar facilitates the handling of future events i.e. predictions, allowing the customer to plan in advance the maintenance activities. Only authorized Users are able to (de)active the Maintenance Mode During commissioning or during maintenance activities, sensors can be set into Maintenance Mode. Thus the data that is generated would not be considered as part of the normal substation operation. Page 22
