The intelligence that every digitalized transformer possesses is housed in a small, unassuming box—the central processing unit (CPU) of the Integrated Smart Module (ISM). It’s the beating heart of our automation solution for power transformers. This box is the point of convergence for all of the signals that are measured by sensors at key points—such as the on-load tap-changer, bushings, or cooling system—and are required for monitoring and control.
The CPU box is perfect for meeting the special requirements of energy technology with regard to reliability, robustness, and durability.
Special software programmed by our in-house specialists evaluates the data that is obtained from this process. The software contains all the expertise on transformers that MR has built up over the decades, and was developed in close partnership with our customers as well as tested in practical scenarios. It contains functions ranging from straightforward limit value monitoring—which signals excessively high temperature values, for instance—to elaborate calculation operations involving complex algorithms that make it possible to determine factors such as potential overload capability.
The integrated web server allows measured values and status data, plus interpretations of this information, to be visualized using any standard browser. In principle, this means that users can monitor the status of their transformers from anywhere—at the transformers themselves, on a control center PC, on a notebook or tablet on the go, and, depending on the network configuration, even from any smartphone. Our components comply with the latest IT security standards, delivering the very best performance in this area. A range of interfaces, including Ethernet, USB, and CAN, also en sures that the equipment is compatible with all current communication interface options.
