  1. Automatic Rack-In Rack-Out System (ARIRO)

  2. Introduction • The indoor types of 11 kV and 33 kV VCBs use a hand-operated crankshaft for racking (rack-in or rack-out) operations

  3. Introduction • During the racking process, an ionization of the area around the main bus bar contacts can lead to ionizing arcs. • These can result in arc blast explosions, threatening the operators’ lives. Arc flash phenomena occur on live bus Explosion on a switchgear caused by arc blast

  4. Introduction • Examples of damaged VCB due to arc explosion.

  5. Introduction • Consequently, personal safety in the field of power distribution is becoming a major concern worldwide. • But, accident do happen……. Third degree burn caused by arc blast Operator with a protective gear

  6. ARIRO The Invention: A life-saving racking system for vacuum circuit breaker Main Objective: For operator’s safety during rack-in and rack-out 11 & 33 kV VCB operations. Main Advantages: • Remotely operated • User Friendly Operation
