509 Direct Winding Transformer Monitor
Brand: Qualitrol CompanyMeasures transformer temperatures (direct winding, calculated winding, main tank oil, load tap changer, ambient).
Consolidates temperature information with alarm contacts and other information using customizable relays.
Accepts most third party sensors for other parameters.
Features- All the features of the Qualitrol 509 ITM
- Real time comparison of calculated and direct (‘hot spot’) winding temperatures for verification of transformer operation to OEM specification
- Up to 8 modular inputs of various types and up to 16 additional fiber optic temperature inputs via digital port when combined with optical hot spot modules
- Cooling monitor model (509-200) for advanced control or load tap changer monitor (509-300) model for detailed performance monitoring
