The Hydran M2 is a compact affordable all-in-one on-line transformer-monitoring device. While permanently mounted on the transformer, The Hydran M2 will alert personnel to developing fault conditions. In addition to providing a composite value of various fault gases (in ppm) and the moisture in oil reading (%RH and ppm), the Hydran M2 can also encompass on-board transformer mathematical models based on IEEE® and IEC® standards to provide further information on the performance of the transformer.
