Product description

Record, process, display and forward operating data for transformers – the TRAFOGUARD® offers you all these functions in a single device. Whether simply displaying a status or generating individual reports, the TRAFOGUARD® features an outstanding variety of functions and a particularly high level of operating convenience. All these features come in a variety of designs (mounted on a cap rail, installed in the tap changer drive or as a 19" device).

The TRAFOGUARD® provides users with maximum flexibility and freedom in combining functions. The system enables customer-specific expansion of basic functions by individually selectable and combinable supplementary modules. Various function packages can be included in the initial order or ordered at a later date. Not only standard functions, such as voltage and temperature measurement, but also wide-ranging functions such as DGA and tap changer monitoring are among the function packages.

Optional automation solutions such as voltage regulation and cooling system control can also be included in the TRAFOGUARD® order and used as supplementary equipment for controlling the transformer.
We are happy to advise you and develop solutions with you that are tailored to your exact needs.
Of course, we can even commission your systems on site by request.

The TRAFOGUARD® transformer monitoring system comes with ISM® technology that we developed.
It is particularly well-suited to the special conditions that are present in the field of electrical energy technology. The simple connection and configuration process for the transformer sensors means that commissioning can be carried out easily
and quickly. In addition to the outstanding monitoring functions, you can also take advantage of the freely available inputs that allow you to configure your transformer monitoring process exactly how you want it. The recorded and evaluated data can be transferred directly to the control system. This greatly reduces the amount of wiring needed during installation and significantly cuts costs compared to a conventional connection method. Visualization takes place via an integrated web server with ISM® Intuitive Control Interface (IICI), so there is no need to spend valuable time installing software packages.
