Dynamic Transformer Rating
Real-time thermal rating and loading of (power) transformers, calculated from loading and ambient conditions, as a native module within the same SUMO platform.
Unlock the real headroom in your transformers.
SUMO extends dynamic rating to power and substation transformers, calculating real-time thermal capacity from loading and ambient conditions so operators can safely use available headroom instead of conservative nameplate ratings. Dynamic Transformer Rating ships as a native module within the same operational environment as Dynamic Line Rating.
Thermal rating from real operating conditions
SUMO models the thermal state of the transformer from load and ambient conditions, revealing the capacity that conservative static ratings leave on the table — and the limits that matter when conditions tighten.
One platform, lines and transformers together
Because DTR runs as a native module alongside Dynamic Line Rating, operators get a single, consistent view of dynamic capacity across both lines and transformers, integrated into the same control-room screens, EMS and (A)DMS applications.
Operational and planning value
Real-time and forecast transformer ratings support day-to-day operations as well as congestion management and planning, with the same continuous archive and analytics SUMO applies across the network.
