<P> In the field of electric power distribution and transmission , a Buchholz relay is a safety device mounted on some oil - filled power transformers and reactors , equipped with an external overhead oil reservoir called a `` conservator '' . The Buchholz relay is used as a protective device sensitive to the effects of dielectric failure inside the equipment . A generic designation for this type of device is `` gas detector relay '' . </P>
