5 Why do we need Gas Density Monitoring? GIS Age Profile (2017) Installation / Commissioning Siemens Installed Base Worldwide Installed Base (CB Bays) Estimation Maintenance Currently we don t know this moment No GIS Bays Time Based Maintenance Condition Based Maintenance Failure Rate Page Early Failure Detection! Despite robustness, the worldwide GIS installation comes to age and rising failure rates are expected. Years in Service 500 Failure Detection and Repair** Reference: CIGRE 2016, Paris ** Simulated dates for illustration purposes Siemens Monitoring Products are easy to retrofit on all brands, supporting in tackling the upcoming challenges.

6 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

7 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 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

An estimated time of warning & tripping is available SF 6 level SF6 warning SF6 tripping If a warning appears when do we have to act? Answer: Unknown SF 6 tripping setting Predicted time of SF6 warning! Predicted time of SF6 tripping! Condition based (optimized) maintenance! Page 8

11 Our Approach 1 Assess 2 Address 3 Act GDM Field Devices ISCM Platform Support Services A scalable System Architecture supports the complete Condition Monitoring Value Chain. All the collected data is easily integrated in one single interface that asses the gas density, address the potential failure and allow the customers to act proactively. Page 11

12 Main Features for field devices 1 Assess Compact and Reliable Hardware Design 44mm 480 mm For Indoor or Outdoor installations EMC Compliance: IEC IEC IEC IEC IEC IEC IEC BS EN CISPR 22 Environmental Standards -25 C to 55 C (operating) - 40 C to 70 C (non-operating) 95% RH, 55 C Vibration Standards BS EN BS EN Specially designed for mounting in a 19 Rack, the Assetguard GDM can survive in harsh substation environments. 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

13 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

Alarm Management Localization Web Based Visualization Page 14

15 Integrated Substation Condition Monitoring (ISCM ) 2 Address Seamless field device Integration LAN Switch Ethernet TCP/IP Up to 50 devices ISCM Gas Density Sensors (4-20mA) Up to 48 Sensors per field device With limited configuration the ISCM receives data (measurements, alarms, predictions) from 50 field devices at the same time An industrial PC hosts the software components for the communication with the field devices The Industrial PC is designed for 24-hour continuous operation, fulfilling temperature, vibration, shock and EMC requirements The ISCM Software runs on various operating system i.e. Windows or Linux Interconnection is achieved thanks to a network LAN Switch, typically Siemens RUGGEDCOM devices Page 15

16 Integrated Substation Condition Monitoring (ISCM ) 2 Address Seamless field device Integration ISCM LAN Switch Ethernet TCP/IP Gas Density Sensors (4-20mA) Up to 50 devices Up to 48 Sensors per field device All the sensor measurements are stored and displayed in a single standardized User Interface that reflects the real customer substation. Thus, 2400 Gas Zones can be monitored within a Single ISCM instance. Page 16

17 Integrated Substation Condition Monitoring (ISCM ) 2 Address SF6 Historical Data Alarm Management SF6 Gas Inventory All the information can be exported!!! Historical Data is stored at least for 5 years. Based on a user-selected period of time, the Historical Data is easily visualized in a chart. For single sensors or complete Substations an Alarm Report or SF6 Gas Inventory can be easily exported as a PDF or Excel file. Page 17

21 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

22 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
