1 Arc-Killer SV-25 – DF-2 + Range Arc-Killer SV-25 - DF-2 + Range

2 Overview 1.General Overview 2.Drive Mechanism 3.Cubicle Integration Arc-Killer SV-25 – DF-2 + Range

3 Overview 1.General Overview 2.Drive Mechanism 3.Cubicle Integration Arc-Killer SV-25 – DF-2 + Range

4 General Overview Arc-Killer SV-25 provides additional safety by minimizing the effects of an internal arc. Less energy released Fewer architectural/structural demands Unit is reusable after an arc Arc-Killer SV-25 – DF-2 + Range

5 SV-25 Basic Principles Arc-Killer SV-25 – DF-2 + Range Pressure build Ignition Ionisation Metal Short Circuit SV-25 triggered Arc extinguished ms fault occurrence

6 Overview 1.General Overview 2.Drive Mechanism 3.Cubicle Integration Arc-Killer SV-25 – DF-2 + Range

7 Drive Mechanism [1] Energy required for operation stored in compression spring Stored energy is blocked until the system receives a trigger signal Arc-Killer SV-25 – DF-2 + Range

8 Drive Mechanism [2] Trigger is not activated: Before arcing occurs in electrical unit As a result of environmental vibrations RP : Test to demonstrate that arc-killers inside both units will not operate during short-time current and peak withstand current test When an electrical fault occurs: Trigger signal is forwarded Stored energy is released Additional earthing knife action prevented Arc-Killer SV-25 – DF-2 + Range

10 Overview 1.General Overview 2.Drive Mechanism 3.Cubicle Integration Arc-Killer SV-25 – DF-2 + Range

11 Integration of Arc-Killer SV-25 Arc-Killer SV-25 – DF-2 + Range Supplementary Earthing knife Drive mechanism SV-25 Trigger signal Expansion volume Earthing knife

12 Safety at all times Arc-Killer SV-25 – DF-2 + Range Cable compartment not accessible. Interlock Earthing Paddle Drive Mechanism SV-25 Released

13 Safety at all times Arc-Killer SV-25 – DF-2 + Range Cable compartment door freely accessible. (Door removed.) Interlock Earthing Paddle Drive Mechanism SV-25 Locked

14 Safety at all times Arc-Killer SV-25 – DF-2 + Range

15 Safety at all times Arc-Killer SV-25 – DF-2 + Range

16 Test & Certificates Tests were carried out in accordance with IEC SV-25 meets the requirements: IAC AFL 20kA IAC BFLR 4.8kA The Arc-Killer is activated quick enough to reduce all harmful effects of an internal arc. As a result, the consequences are negligible. Arc-Killer SV-25 – DF-2 + Range
