About the High voltage laboratory

The Tony Davies high voltage laboratory (TDHVL) is a centre for research into dielectric materials and insulation systems, as well as high voltage and related phenomena. The lab houses state-of-the-art facilities and is supported by a specialist engineering team who are all involved in the latest research. We are also a commercial testing house and offer a consultancy service.
