Having been in existence for over 25 years we can say with some confidence that many of our early products are still in service; with the rigorous standards we set ourselves we see this continuing into the future. Support for these legacy products is still available and in some cases replacements for existing schemes can also be manufactured, please get in touch here for more information.

The SuperTAPP system comprises a voltage control relay type RVM and a tapchanger monitor relay type RTMU.
