Method Benefits; 11.1.6 Remote Monitoring With Host Computer; Data Reading - GE Hydran 201 i Instruction Manual

For details, see the Hydran Host Software Manual.
Note: Other softwares can be run on the host computer at the same time as the Hydran Host
software.

Method Benefits

The advantages of this method are as numerous as important:
• Gas 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 networked electronic intelligent devices (such as the Hydran 201Ti and the
Hydran 201Ci) is a mature technology with an extensive future.

11.1.6 Remote Monitoring With Host Computer

The remote monitoring with host computer method consists of connecting a host computer
running the Hydran Host software to a Hydran 201i System or to one or several network(s)
of Hydran 201i Systems located at different locations, through a telephone system and a
modem link.
Remote monitoring offers the same features and benefits as local monitoring, plus:
• A modem can be connected to any Hydran 201i System in a local network. The modem
is typically installed in any of the local network's Hydran 201Ci Controllers.
• The modem of the local network is connected to a telephone line.
• The host computer equipped with a modem and the Hydran Host software communicates
with the Hydran 201i System network(s), thus simplifying the monitoring process.
• Each power station can have its own, independent network.
• The station can be entirely automated (unmanned).

DATA READING

Data (gas level, hourly and daily trends, alarm messages, etc.) can be read as follows:
• Direct reading using a Hydran 201Ti, a Hydran 201Ci controller or the Hydran Host
software: See Section 11.2.1 on page 11-6.
