scope:
Covers the gas and oil actuated relay (Buchholz relay) for liquid immersed power transformers and reactors with conservator for indoor or outdoor installation. The device is intended to detect - gas release from the unit to be protected, - oil surge from the tank to the conservator, - complete loss of oil in the conservator. This part defines the - operating limits, - dimensions, - operational performance, - electrical characteristics, - dynamic characteristics. It applies to relays with dry contacts.
