In practice, TOR-5 does not eliminate the need for chromatographic DGA, it complements it. TOR-5 continuously tracks key indicator parameters such as hydrogen, moisture, and trends, which is very effective for early fault detection and alarming. However, it does not provide full multi-gas composition (methane, ethane, ethylene, acetylene) required for fault type classification. Periodic laboratory chromatography is still necessary for root-cause analysis and condition assessment, while TOR-5 mainly reduces the risk of missing fast-developing problems between scheduled DGA tests.
