Sometimes referred to as tap changer control relays, these products are used to control the on load tap changer (OLTC) connected to power transformers. We are able to offer different types of relay and accessory products.
Expertly engineered solutions
Helping you face the challenges of today’s grid control, we use our specialist engineering skills to bring you modern solutions for an ageing network.
Our voltage control products include some of our proudest inventions, including our pioneering SuperTAPP n+®, renowned for its impeccable performance and reliability.
Have a look at our full range:
Voltage control relays are normally mounted in a control panel, which can be installed outside in a substation compound near the transformer, or inside a substation building remote to the transformer.
These products are used to aid fault finding on electricity distribution networks and reduce the disruption to consumers during fault conditions.
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.
