المميزات والفوائد
- Photoacoustic spectroscopy measurement principle provides ppm-level sensitivity across all 9 IEC 60599 fault gases simultaneously, enabling Duval triangle and Rogers ratio fault diagnosis without manual laboratory oil sampling or external gas chromatograph equipment.
- Continuous sampling every 1–24 hours (configurable) provides near-real-time visibility of transformer gas generation trends, detecting the gradual increase characteristic of paper insulation aging and winding hotspot development weeks before critical gas levels are reached.
- Built-in Duval triangle, Rogers ratio, and IEC 60599 concentration limit analysis generates automatic fault type diagnosis (thermal fault, partial discharge, arcing) and prioritised alarm outputs, without requiring specialist DGA interpretation by the operations team.
- ATEX Zone 1 certification and -20°C to +60°C operating range allows direct installation on transformer bodies at outdoor substations across Saudi Arabia's climate range, from coastal humidity to desert summer temperatures above 50°C.
- IEC 61850 communication with GOOSE alarm messaging enables direct integration into modern digital substation automation platforms, reporting transformer gas alarm events as IEC 61850 datasets to the substation protection and control IED.
- Three configurable alarm thresholds per gas (advisory, alarm, emergency) with independent relay outputs allow hierarchical alert escalation from email notification to automatic transformer de-loading or disconnection based on gas level severity.
- Web-based HMI accessible over Ethernet allows remote review of transformer gas trends, alarm history, and Duval triangle status without site visit, enabling centralised monitoring of multiple transformers from SEC regional control centres.
التطبيقات الصناعية
- High-value 33/11 kV and 132/33 kV distribution transformers at SEC's critical urban substations in Riyadh, Jeddah, and the Eastern Province, where ECRA grid reliability requirements justify continuous condition monitoring to prevent unplanned outages.
- ARAMCO crude oil processing facility main transformers at GOSPs and refineries, where an unplanned transformer failure causes production losses measured in millions of SAR per hour, making continuous DGA monitoring economically essential.
- SABIC polymerisation and petrochemical plant generator transformers at Jubail Industrial City, where transformer condition data is integrated into the plant's DCS asset management system for condition-based maintenance scheduling.
- Generator step-up transformers at SEC's combined cycle and gas turbine power stations, where online DGA monitoring supplements periodic oil sampling to detect inter-turn faults and bushing degradation between planned maintenance outages.
- Strategic reserve transformers and spare transformer assets in SEC's transformer management program, where periodic online monitoring during storage verifies transformer condition before energisation at a new substation location.
- NEOM utility infrastructure transformers in the high-voltage distribution network, where ABB Ability cloud integration of TVOC-2 data enables the smart grid's predictive asset management algorithm to schedule transformer maintenance before condition degradation reaches critical levels.
- Offshore platform power transformers in ARAMCO's offshore field installations, where the ATEX Zone 1 certification and sealed IP-rated enclosure allow installation in classified hazardous areas without additional protection measures.
