A new solution for a domestic low voltage surge-arrester

This article presents a new product, developed by the authors, which made the object of a research contract and a technological transfer, from university to industry and mass production. It is a low voltage class D surge-arrester, based only on metal-oxide varistors, a state of the art electronic device used to protect domestic and similar consumers against any type of overvoltage (pulse or long time). On the first stage, it was developed after some research studies carried out by the authors at the Paul Sabatier University/Laplace Laboratory in Toulouse, France in partnership with the Politehnica University in Timisoara, Romania. The applicative research was transferred, in order to be produced at PROTENERGO S.A., a local electronic products manufacturer in Timisoara. It has some original ideas which make this product cheaper, easy to use and adapted to any low voltage installation existing even in ancient buildings. It could be the description of a simple technological transfer between the academic environment and the industrial one.
