The Hydran M2 is a compact permanently mounted on-line transformer monitoring device that will alert personnel to developing fault conditions. It continuously monitors a composite value of various fault gases (in ppm) or a Hydrogen gas only value (depending on sensor purchased). In addition it tracks moisture in oil (reading in %RH and ppm).
With additional sensors added, the Hydran M2 can also compute transformer mathematical models based on IEEE® and IEC® standards to provide further information on the performance of the transformer.
