eVD4 - The Smart eVolution Advantages © ABB Group 15. April 2017 | Slide 14 14

eVD4: The Smart eVolution Performance improvements and integration advantages Performance improvements by component harmonization and optimization leading to a MV system simplification and to an increase of the overall reliability. The eVD4 offers specific advantages compared with a standard MV solution in all stages of the panel life cycle 15

Advantages along the panel life cycle Specification and ordering Specification and flexibility: No need to define any parameters for the sensors RBX615 pre-configuration can be customized Supply management: A complete MV solution (CB, Relay and Sensor) can be obtained with just one single order and one single reference 16

Advantages along the panel life cycle Installation, Less wiring, Flexibility The eVD4 is a ready to install solution. The components are internally wired. All the wiring is instantaneously connected to the switchgear through the CB plug. Less effort for engineering and wiring: The switchgear is highly standardized Less risk of errors and increased safety and reliability Easier and faster engineering Shorter and reliable connections Flexibility for last minute modification: The integrated solution is more versatile and flexible. 17

Advantages along the panel life cycle Installation, Less wiring, Flexibility – Low Voltage Compartment Standard circuit breakers eVD4 18

Advantages along the panel life cycle Testing, Maintenance, Spare parts Easy and complete testing of the whole measurements chain by primary injection: It is possible to test the whole measurement chain by a primary injection in the CB contacts, easily accessible without any modification in the panel. Easy maintenance, reduced Mean Time To Repair (MTTR): Standard accessories with few variances, readily available for easy maintenance. Self-diagnostic functions System quickly repaired in case of failure (no stops in production) Optimization of the spare parts in stock 19

Advantages along the panel life cycle Testing, Maintenance, Spare parts Easy removable integrated protection and control unit: The unit is fixed in a docking unit by means of screws Facilitates easy access and service

Advantages along the panel life cycle Retrofit and revamping Extremely simple and straightforward solution for retrofitting and revamping: Faster and easier revamping process Flexibility thanks to sensors high range of linearity and RBX615 programmability No need to act on CTs and VTs as they come with the eVD4 Reduced effort for wiring and retesting 21

Advantages along the panel life cycle Switchgear simplification and easy operation Specification Ordering Easy to install Less effort for engineering and wiring Less effort for Factory Acceptance Test (FAT) while increasing safety and reliability Flexibility and easier last minute modifications Extremely simple and straight forward solution for retrofitting and revamping Easy maintenance and reduced Mean Time To Repair (MTTR) Optimization of the spare parts in stock 22
