Gas Relay Detectors – Buchholz type

These are one of the most important transformer protection accessories available. They work by detecting gases that may be accumulated within their chamber for lack of oil or by oil flows resulting from internal electric discharges or a shorted transformer.
Each relay is set, simulated and tested within values that are defined by international standards.
