2 Introduction to the Hydran M2-X
2.1 Overview
The Hydran M2-X is an intelligent, on-line monitoring system that measures the
level of combustible gases and moisture in dielectric oil for the evaluation of
dangerous conditions, bubbling temperature and aging rate, and for the early
detection of incipient faults in trans-formers (or any other oil-filled electrical
equipment).
The Hydran M2-X consists of a Type NEMA 4X enclosure (Figure 2-1) easily
installed on one of the valves of the equipment to be monitored.

The Hydran M2-X’s user interface (Figure 2-2) consists of an eight-key membrane
keypad and a 128 x 64 pixels, backlit liquid crystal display (LCD) to use the Hydran
M2-X as a stand-alone unit. For more information on the user interface, see Chapter
