The comprehensive online monitoring system for transformers is to monitor the health status of equipment online and identify early signs of potential problems. The main monitoring parameters for transformer online monitoring include pressure, temperature, oil level, generation and accumulation of dissolved gas (DGA) in oil, partial discharge, bushing monitoring, and load switch voltage regulation function. And Qualitrol's QTMS is to gather data from all sensors on the transformer to reflect the overall health status of one or more transformers. ·Two different sizes of 3U and 6U ·Consolidate the data of all sensors, with multi-level security measures to protect the data. The system is easy to use, reducing the time required for installation and resetting Supports up to 14 input/output modules, which can be configured arbitrarily. Users can choose to add display modules to their own system Hardware modules and software can be completely upgraded by users on site, easy to maintain, and do not require frequent technical support ·Front panel wiring, convenient and easy to connect ·Universal power supply with high flexibility The module supports hot swapping, making it easy to change the configuration of QTMS units in use
