HYDRAN M2 HYDRAN系列永久安装在线变压器监测设备

Hydran M2是一种紧凑的永久安装在线变压器监测设备，将提醒人员发展故障条件。它连续监测各种故障气体的复合值(以ppm为单位)或仅监测氢气值(取决于购买的传感器)。此外，它还跟踪油中的水分(以%RH和ppm读数)。

通过添加额外的传感器，Hydran M2还可以根据IEEE®和IEC®标准计算变压器数学模型，以提供有关变压器性能的进一步信息。

HYDRAN M2

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.
