7.1.5.1 Method Benefits
The advantages of this method are as follows:
• Gas and moisture level monitoring can be fully integrated to the transformer
or station monitoring.
• Cabling is minimized.
• Reliability and performances are greater than those of methods based only
on alarms and analog outputs monitoring.
• The use of network electronic intelligent devices (such as the Hydran M2-X) is
a mature technology with an extensive future.
7.1.6 Remote Monitoring With a Host Computer
The remote monitoring with host computer method consists of connecting a host
computer running the Perception software to a Hydran M2-X or a network of Hydran
M2-X’s, through a modem connection or an Ethernet network. See Chapter 5.
Remote monitoring offers the same features and benefits as local monitoring,
plus:
• Each power station can have its own, independent network.
• The station can be entirely automated (unmanned).
• A remote computer could monitor several stations from one location.
7.2 Data Reading
Data (gas and moisture level, hourly and daily trends, alarm messages, etc.) can
be read as follows:
• Direct reading (Section 7.2.1).
• Reading of the history files data (Section 7.2.2).
7.2.1 Direct Data Reading
Data can be read directly as follows:
• With the Hydran M2-X: Its user interface includes a keypad and a display. For
details, see Chapter 3.
• With the Perception software: A host computer running the Perception
software remains the easiest way to read data. The host computer screen
provides a more convenient interface than the one of the Hydran M2-X. For
details, see the Perception Software Manual.
