Qualitrol 509 DW Intelligent Transformer Monitor With Direct Winding

QUALITROL 509 DW INTELLIGENT TRANSFORMER MONITOR WITH DIRECT WINDING

Real time comparison of calculated and direct winding temperatures

Measures 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

Option

All options available on the QUALITROL 509 ITM
Neoptix® T2T temperature sensors, fiber optic extension cables, optical feedthrough, tank wall plate style (bolt-on or weld-on) and junction box
Optical hot spot module (up to 8 fiber inputs per module) for constant monitoring
Portable fiber optic thermometer for single probe verification and monitoring

Application

For remote and local monitoring of all critical oil filled transformer parameters including cooling system control and load tap changer monitoring. Special model for real time comparison of calculated and direct winding temperatures.
