Product description

Capture, evaluate, store,
and visualize transformer data
and drive the on-load tap-changer.
TAPMOTION® ED ISM®. Integrated intelligence.

As well as driving the on-load tap-changer, the TAPMOTION® ED ISM® enables all relevant power transformer operating data to be captured and evaluated: For example, tap-changer monitoring or evaluations of transformer utilization. TAPMOTION® ED ISM® helps to purposefully plan operation and maintenance. The sturdy housing protects both the tap changer's motor-drive unit and the cost-efficient, integrated monitoring system. The TAPMOTION® ED ISM® is ideally suited to upgrading monitoring of older and smaller transformers. Automation solutions such as voltage regulation and cooling control are optionally available with the TAPMOTION® ED ISM® and can be used as complement for transformer control. We would be happy to advise and help develop solutions tailored to your needs. Of course, we can also undertake commissioning on site if requested.

Minimum wiring, maximum flexibility.

The intelligent TAPMOTION® ED motor-drive unit is delivered from the factory with our ISM® Technology. This is particularly well suited to the special conditions of energy technology. Commissioning is quick and easy as the transformer sensors can be connected and configured with ease. In addition to the superior monitoring functions, you also benefit from the freely assignable in- and outputs, enabling you to design your transformer monitoring as you wish.

The data captured and evaluated can be transferred directly to the control system. This greatly reduces the amount of wiring needed during installation and significantly cuts costs compared with the conventional connection method. An integrated web Server with ISM®  Intuitive Control Interface (IICI) displays the data so there is no need for the time-consuming process of installing software packages.
