One Tap Ahead

On-load tap-changers are important devices for the stability of the network voltage. Our customer's requirements are exceedingly complex. That is why tailor-made problem solutions are developed by our specialists. Our motto: solutions from MR are distinguished by perfect functionality, low maintenance and long working life. We are not satisfied unless our customers are.

For about 80 years now we have been manufacturing on-load tap-changers and we still keep coming up with epoch-making innovations. The VACUTAP® series with its vacuum switching technology for on-load tap-changers in oil-immersed and dry-type transformers is now the most common form of technology in reactor-type tap-changers and has revolutionised resistor-type tap-changers.

We have been using this technology since the 1980s and are continuously refining it thus bringing you advantages such as no maintenance requirements before 300.000 switching operations. This has drastically reduced costs and increased availability of the transformer. To mention but a few of the many benefits: no oil carbonization, no replacement of contacts and no oil filter required.

HIGHVOLT Prüftechnik Dresden GmbH

HIGHVOLT Prüftechnik Dresden GmbH is the leading manufacturer of high voltage test equipment with more than 100 years of experience. We produce test systems for factory routine and on-site testing of transformers, cables, GIS and electrical components like bushings, tap-changers, etc.

Our product range includes AC and DC test systems as well as impulse voltage and current test systems. In addition, we also provide HV measuring devices. As a manufacturer of complete test systems, HIGHVOLT is an experienced turnkey supplier of large HV test fields, too. Furthermore, we offer the calibration service for measuring devices and the upgrade of control units and existing test fields.

As a pioneer in the development of mobile AC test systems, HIGHVOLT designed a new generation of mobile test systems for testing of power transformers. The new test system is based on a static frequency converter which replaces the motor-generator (M/G) sets. The compact and light weight design enables a cost effective realization of transformer testing in factory or directly on site.
