المميزات والفوائد
- Sub-millisecond (<1 ms) optical arc detection responds to the arc flash's light output before conventional overcurrent relays register the fault current, reducing incident energy at the fault point by a factor of 10–100× compared to overcurrent-only protection — the fundamental mechanism for achieving NFPA 70E Category 2 or Category 1 PPE levels at LV and MV switchgear.
- Zone-selective detection with up to six independent fibre-optic loops enables the TVOC-2-FO to identify which specific compartment (incoming, busbar, or outgoing) contains the arc fault and issue a trip command only to the circuit breaker feeding that compartment — maintaining supply to healthy compartments and limiting production impact of arc fault events.
- Combined optical plus overcurrent validation mode prevents nuisance trips from non-fault light sources (inspector torches, camera flashes, maintenance lighting) by requiring both an optical signal above threshold AND a current above the minimum arc fault level before issuing a trip command — eliminating false trips that would otherwise disrupt production.
- Fibre-optic sensing loop immune to electromagnetic interference (EMI) from high-current switching events, radio frequency interference (RFI) from communications equipment, and power frequency interference — providing reliable detection in the extreme electromagnetic environment of switchgear during fault conditions without signal masking.
- Direct hardware trip output via dedicated relay contact bypasses the normal protection relay trip circuit and connects directly to the circuit breaker shunt trip coil, achieving the minimum possible time from arc flash detection to breaker contact separation — typically reducing total fault clearance time to under 10 ms including breaker opening time.
- NFPA 70E and IEEE 1584 arc flash hazard analysis integration: the Arc Guard's sub-millisecond arcing time is used in the IEEE 1584 incident energy calculation to demonstrate NFPA 70E PPE category compliance, enabling ARAMCO and SABIC contractors to reduce calculated incident energy values in arc flash studies for specific switchgear positions.
- Retrofit installation capability for existing switchgear without modification to the main bus or primary protection scheme — the TVOC-2-FO mounts in the relay compartment on DIN rail, and the flexible fibre-optic sensing loops are routed through existing cable entry points into the switchgear compartments requiring protection.
التطبيقات الصناعية
- New 13.8 kV and 33 kV MV switchgear at ARAMCO and SABIC facilities where SAES-P-100 and SABIC SESG electrical engineering standards require arc flash protection on main switchboards with calculated incident energy above 8 cal/cm² — the NFPA 70E threshold requiring Category 2 PPE that many high-fault-level switchboards exceed without arc flash mitigation.
- LV main switchboard arc protection at NEOM and Red Sea Project critical infrastructure electrical rooms, where the project developers' safety specifications require incident energy below 8 cal/cm² at all main switchboard locations to comply with international arc flash safety standards for workers maintaining the electrical infrastructure.
- MV motor control centre (MCC) arc protection at SWCC and MARAFIQ desalination plant high-voltage motor starter panels, where the combination of high fault current levels (>50 kA prospective fault) and continuous operator attendance during plant startup operations creates elevated arc flash risk requiring optical arc detection.
- Offshore platform main switchboard arc protection at Saudi Aramco offshore field installations, where ARAMCO's SAEP-303 electrical safety procedure requires arc flash incident energy analysis and mitigation measures on all offshore main LV and MV switchboards, and the TVOC-2-FO's fibre-optic sensing is immune to the offshore platform's high EMI environment.
- Data centre critical UPS and distribution switchboard arc protection at Riyadh hyperscale data centres, where IEC 62305 protection requirements and the data centre operator's electrical safety policy require arc flash protection on all main switchboards in the critical power path to protect personnel performing maintenance activities under Permit to Work procedures.
- Retrofit arc flash protection for existing aging switchgear at Saudi industrial facilities under ARAMCO and SABIC electrical safety improvement programmes, where the TVOC-2-FO's non-intrusive fibre-optic sensor installation provides arc flash protection without requiring switchgear replacement — achieving incident energy compliance at a fraction of the cost of full switchgear replacement.
- Hospital and healthcare facility main electrical switchboard arc protection at Ministry of Health and private hospital developments, where Joint Commission International (JCI) Life Safety standards and NFPA 101 healthcare facility requirements mandate arc flash incident energy analysis and PPE hazard assessment on all electrical panels, with Arc Guard providing the engineering control that reduces calculated incident energy to manageable levels.
