  16. SIMOPRIME: Benefits Peace of Mind 2. Saves Lives 3.Increases Productivity 4. Saves Money

  17. SIMOPRIME: Benefit No. 1 Peace of Mind

  18. Peace of Mind: How? Fulfilling all the mandatory type tests requirements of new IEC 62271-200 1. Tests to verify the insulation level ( power frequency and impulse ). 2. Temperature rise and measurement of resistance of circuit. 3. Tests to prove the withstand capability of main and earthing circuits subjected to rated peak and short time withstand currents. 4. Test to prove the making and breaking capacity of the circuit breaker inside the switchgear panel.

  19. Peace of Mind: How? Fulfilling all the mandatory type tests requirements of new IEC 62271-200 5. Test to prove the satisfactory operation of switching devices and removable parts. 6. Tests to verify the protection of persons against access to hazardous parts and the protection of the equipment against solid foreign objects + The stringent requirement of Internal arc testing as outlined in new IEC

  20. Peace of Mind: How? SIMOPRIME can be freely used on GOST standard countries. The certification is valid to 6kV and 10kV systems

  21. Peace of Mind: How? 3AH5 VCB SION VCB 3AH5 and SION breaker tested insidethe panel, means higher operational reliability.

  22. Peace of Mind: How? Preventive mechanical interlocks avoid incorrect operations.

  23. Peace of Mind: How? Preventive Mechanical Interlocks 1.Operation of switching device is possible only when the switching device truck is in end position. 2.Moving of switching device truck from SERVICE to TEST is possible only when the switching device is switched OFF.

  24. Peace of Mind: How? Preventive Mechanical Interlocks 3.Moving of switching device truck from TEST to SERVICE position is possible only when the switching device is switched OFF, the low voltage plug is connected and the earthing switch is switched OFF. 4.Operation of earthing switch is possible only when the switching device truck is in TEST position.

  25. Peace of Mind: How? A redundant force ventilation system will automatically work in case of a fail on the main ventilator. Both ventilators have independent systems and can be replaced on site.

  26. Peace of Mind: How? • Earthquake qualification • IEC 68-3-3 • UBC zone 4 • Transelec requirements (Chile) • No damage or an unwanted operation during an unexpected earthquake

  27. Peace of Mind: How? SF6 CB: 22% MOCB: 14% VCB: 64% World Market shares - Medium Voltage Switching technologies Vacuum interrupters - a highly proven and widely used technology, world-wide.

  28. Peace of Mind: How? Freedom from manufacturer’s monopolistic policies + Open communication protocol relays Standard Instrument transformers

  29. Peace of Mind: How? ISO Certification Siemens has consistent quality standards for all products, processes and manufacturing centres.

  30. Peace of Mind: How? Europe S o u t h A m e r i c a A s i a Global village a reality A true international switchgear based on global best practice sharing and experience.

  31. Peace of Mind: How? s One word says it all!

  32. Peace of Mind: Summary

  33. Peace of Mind: Summary

  34. SIMOPRIME: Benefit No. 2 Saves Lives

  35. Forecast: Saves Lives How many: Even one life! How soon: As soon as you energize Siemens SIMOPRIME switchgear!

  36. Saves Lives: How? All operations behind closed door 1.All switching operations including emergency manual operations 2.Feeder earthing 3.Rack-in / rack-out operation of Switching device truck. 4.Not- Emergency manual charging of VCB operating mechanism.

  37. Saves Lives: How? Front door interlocks 1. Racking of VCB truck from Test to Service position not possible until the front door is closed and locked. 2.Front door cannot be closed and locked until the LV control plug is securely connected. 3.Front door cannot be opened until the VCB is switched OFF and racked out in Test position.

  38. Saves Lives: How? Partition class: PM 1. Earthed metallic shutters and partitions ensure partition class PM. 2. Class PM ensures no electric field in the opened compartment and no electrical field change in the adjacent compartments. 3. Thus partition class PM ensures safe maintenance when the switching device chamber is opened while keeping the busbars as well as cables under charged conditions.

  39. Saves Lives: How? • What is an internal arc?It is a high resistance arc fault within the switchgearenclosure due to insulation failure. • What are the effects of an internal arc fault?The fault current passing through the electric arc increases the air temperature inside the faulty compartment. The hot air expands and exerts very high pressure on thecompartment walls and doors. If the switchgear is notdesigned and qualified for an internal arc, thehigh pressure can rupture the enclosure and endangers the life of persons working near the switchgear.

  40. Saves Lives: How? This is what will happen if the switchgear is not designed and qualified for internal arc. start Internal Arc Test.mpg Film Imagine what will happen to your operator.

  41. Saves Lives: How? • What happens when there is an arc fault • in an Internal Arc Classified switchgear • as per IEC 62271-200. • Correctly secured door and covers do not open. • No fragmentation of the enclosure occurs within the timespecified for the test. • Arcing doesn’t cause holes in the accessible sides up to aheight of 2 m. • Cotton test indicators do not ignite due to the effect ofhot gases. • The enclosure remains connected to its earthing point.

  42. Saves Lives: How? If this failure happened in your SIMOPRIME, no one would even be hurt.

  43. Saves Lives: How? Vacuum Circuit Breaker means no explosion is possible.

  44. Saves Lives: How? SF6 CB SIEMENS CB start SF6 circuit breaker.mpg Film start vacuum circuit breaker.mpg Film Which interrupter would you prefer?

  45. Saves Lives: How? • Arc medium free from toxic by-products • 2.Environment friendly and compatible

  46. Saves Lives: How? Make proof earthing switch tested inside the panel.

  47. Saves Lives: Summary

  48. Saves Lives: Summary

  49. SIMOPRIME: Benefit No. 3 Increases Productivity

  50. Increases Productivity: How? Metallic and earthed shutters and partitions Safe to touch Loss of Service Continuity category LSC2B-PM Maintenance in switching device compartment possible without de-energising the corresponding cable connections and busbars.
