Qualitrol 509 ITM Intelligent Transformer Monitor
Qualitrol 509 ITM Intelligent Transformer Monitor
The Qualitrol 509 ITM is an advanced transformer monitor for all parameters required to accurately track and control power transformers. Capabilities include data logging, event recording and dynamic loading analysis help to optimise loading and maximise asset life.
The Qualitrol 509 can be used for remote and local monitoring of all critical oil filled transformer parameters including cooling system control and load tap changer monitoring.
Improve transformer asset protection and utilisation
The 509 is a complete transformer monitoring system that ensures at all times you can know your transformer health, optimise loading and equipment life, and conduct root cause analysis for condition-based maintenance with ease.
In addition to traditional mechanical monitoring and protection, electronic transformer monitoring further improves reliability, safety, and the availability of key decision making information by automating control and making information available remotely.
An Introduction to Qualitrol Intelligent Transformer Monitors
Watch Qualitrol’s video to hear about how the 509 provides expanded capabilities such as direct winding measurement, all in a single device, enabling users to avoid installation, maintenance and capital cost on additional devices.
509-100 Intelligent Transformer Monitor
For general transformer control
The Qualitrol 509-100 ITM monitors many standard parameters such as liquid temperature, winding temperature, load current, oil level, and mechanical alarm.
509-200 Cooling Monitor
For general transformer and advanced cooling control
The Qualitrol 509-200 monitors the same standard parameters as the 509-100 such as liquid temperature, winding temperature, load current, oil level, and mechanical alarm.
It adds to this cooling monitor and control functions, which learns as it operates, automatically calculating maximum, minimum, and average values for determining set points.
509-300 Load Tap Changer Monitor
For general transformer and load tap changer monitoring
The 509-300 includes all standard parameters such as liquid temperature, winding temperature, load current, oil level, and mechanical alarm.
It provides in depth monitoring of the Tap Changer, including differential temperature, tap position, mechanism, motor performance, detection of proper tap movement, contact wear and logging of tap position history.
It provides alarms for contact loading (instantaneous and cumulative), excessive tap counts over time, false tap movements, false or no motor movement, motor and mechanism problems (overloading, breakage, binding) and worn tap contacts or coking.
509 DW Direct Winding Monitor
For monitoring on the most critical transformers
The 509 DW retains the basic monitor functions including many standard parameters such as liquid temperature, winding temperature, load current, oil level, and mechanical alarm
It provides real-time comparison of direct and calculated winding temperatures via integration with fibre optic temperature measurement - enabling hot spot temperature measurement of the actual temperatures wherever the probe is installed directly.
This enables maximised cooling efficiency with more accurate hot spot temperature measurement. The 509 DW can be combined with cooling or load tap changer monitor series for additional transformer monitoring functionality.
