In most cases, yes – each transformer requires its own TOR-5 unit, because the system is designed to continuously monitor oil parameters directly from a specific transformer. Moisture, gas content, temperature, and trends are highly individual and depend on load profile, insulation condition, and aging history. Using one system for multiple transformers would break the principle of real-time diagnostics and make trend analysis meaningless. However, some plants use portable analyzers for periodic checks, but that is a different approach and cannot replace a dedicated online system for critical assets.

Can TOR-5 generate and purify transformer oil?

No — the TOR-5 is an online monitoring and diagnostics system for transformer oil; it measures parameters such as moisture, dissolved gases, temperature and trends but does not physically generate or purify oil. Oil generation, dehydration, degassing and particle removal require mechanical treatment steps (heating, vacuum dehydration, filtration, adsorption/regeneration) that are performed by dedicated oil purification and regeneration equipment.

In practice you should use TOR-5 to continuously monitor oil condition and set alarm thresholds so that, when moisture, dissolved gas or contamination exceed limits, a vacuum oil purifier or oil regeneration unit is scheduled to treat the dielectric fluid. Integrating TOR-5 alarms with a maintenance program allows targeted use of vacuum dehydrators, filters and adsorbents to restore transformer oil quality and extend insulation life.
