Filter resistors
Construction and execution
Network quality and safety, reduction of the reactive power and requirements regarding the reliability of assemblies and components have been increasing in significance for years. With the help of filter circuits, it is possible counteract these undesirable effects.We supply filter resistors for this purpose with resistances of just a few watts and with compact dimensions, for use in device assemblies, e.g. as overvoltage protection, and ranging right up to complete, several kilowatt filter systems for medium voltage application.
Since filter resistors have to be designed specifically for the end application, we work closely alongside the customers. Based on the specification, we propose the right resistors and also design the final set-up on request. In the case of device applications, this may entail the construction on additional holders, preparation of special terminals or even the prefabrication of ready-to-mount assembly modules. For low and medium voltage applications, the design and construction depends primarily on whether the installation is indoors or outdoors and how the filter elements are to be cooled. If required, depending on the place of installation, increased clearance and creepage dis- tances can also be implemented, in order to prevent danger caused by dirt and contamination or increased atmospheric humidity and thus, to enhance the service life of the installations.
The production of these installations complies with the applicable standards and norms and the specifications of the electricity supply companies concerned.
