نظام كشف القوس الكهربائي ABB — نظرة عامة
نظام كشف القوس الكهربائي ABB يستخدم مستشعرات ضوئية وقياس التيار للكشف عن أعطال القوس الداخلي في أقل من 1 مللي ثانية، مما يقلل طاقة حادثة القوس بشكل كبير. وحدة TVOC-2-IO تعالج إشارات من حتى 9 مناطق حماية مستقلة.
مُحدَّد في معايير السلامة الكهربائية لأرامكو SAES-P-003 وسابك ومنشآت NFPA 70E. توفر راز الشرق الأوسط دراسات تحليل مخاطر القوس الكهربائي وتصميم النظام والتركيب والتشغيل في المملكة.

المميزات والفوائد
- Sub-millisecond optical arc detection combined with 3–5 ms total trip time limits arc flash incident energy to below NFPA 70E Category 1 (1.2 cal/cm²) in most MV and LV switchgear applications, eliminating the need for full PPE during normal operation near energised equipment.
- Current confirmation function cross-checks optical light detection with a simultaneous current surge measurement, preventing nuisance trips from inspection flashlights, ambient light intrusion, and phone screens common in Saudi Arabia's heavily maintained industrial switchgear rooms.
- Up to 9 independent protection zones per TVOC-2-IO unit with individual trip relay outputs enable zone-selective arc flash clearing — tripping only the upstream breaker for the faulted compartment, maintaining supply continuity to unaffected switchgear sections.
- Loop optical fibre sensors cover the full length of cable chambers, busbar zones, and horizontally extended switchgear compartments where a single point sensor cannot guarantee detection across the entire protected volume.
- Retrofittable to existing LV and MV switchgear panels by routing flexible optical fibre sensors through existing conduit entries and cable routes, enabling arc flash protection upgrades on in-service switchboards without major panel modification.
- IEC 62271-200 IAC (internal arc classified) arc withstand switchgear, combined with the TVOC-2-IO detection system, provides the dual layer of passive mechanical containment and active fast clearing required by ARAMCO SAES-P-003 and NFPA 70E for highest-risk switchgear installations.
- Self-monitoring function continuously checks optical sensor continuity and central unit power supply, generating a fault alarm if any sensor or supply circuit fails — ensuring the protection system is available when needed and alerting maintenance teams to failed sensors before they are needed.
التطبيقات الصناعية
- MV switchgear arc flash protection at ARAMCO GOSPs, refineries, and processing facilities, where SAES-P-003 arc flash hazard mitigation requirements and the proximity of operational personnel to energised switchgear make active arc detection mandatory.
- LV motor control centre (MCC) arc flash protection at SABIC petrochemical plants in Jubail, where the combination of high fault current levels and frequent maintenance access creates elevated arc flash incident energy risk without active detection.
- Hospital critical power distribution switchgear at King Fahd Medical City and Vision 2030 hospital infrastructure, where arc flash detection protects maintenance teams from incident energy levels that standard PPE cannot adequately mitigate.
- Data centre main and distribution switchboard arc flash protection in Riyadh's hyperscale and co-location facilities, where the combination of high fault current and 24/7 operational requirements demands the lowest possible arc flash incident energy.
- NEOM primary distribution substation switchgear, where arc flash detection is included as a mandatory specification in the substation design requirements alongside IEC 62271-200 IAC arc withstand rated switchgear panels.
- Airport and metro infrastructure switchgear protection at KAIA expansion and Riyadh Metro Phase 2 substations, where NFPA 70 and IEC 60364 arc flash mitigation requirements are enforced by the project's international engineering consultants.
- Offshore platform switchgear at ARAMCO's offshore field installations, where the combination of ATEX requirements, high fault current from platform generation, and personnel in close proximity to switchgear makes fast arc detection a critical safety requirement.
