General information on power-
monitoring software
Software, a tool serving site operation.
A site can be compared to a living organism.
The power system manger has no control
over the changes that affect this organism,
but must ensure that it continues to receive
the energy it requires.
Similar to a doctor, the power system
manager must carry out preventive
measures and diagnose and remedy any
problems that occur. The goal is to maintain
the site in a healthy state, without
generating any secondary effects.
Software enables managers to diagnose the
causes of most problems encountered on
electrical systems.
More and more devices are capable of communicating.
The number of available measurements is also on the rise, creating the need for a
tool to successfully manage all the information.
The main purpose of software is to simplify complex sites so that they can be
managed by humans:
b make the site and its operation intelligible
b make the power system tangible and visible.

All measurements at a single location
All measured values may be accessed via a PC.
Organisation and use of measurements
Before they may be used, certain measurements must be organised, processed or
integrated in special tools.
Examples
b organisation:
v organisation in tables
v visual presentation (bar charts, meters)
v etc.
b processing:
v classing of events from different devices in chronological order
v etc.
b tools:
v display in curve form (selection of intervals, magnifying glass, changes in
presentation, etc.).

Device setup, example of a Circuit Monitor
Simple devices may be set up on their front panels.
For devices with advanced functions, local setup is often difficult and even
impossible for some functions.
Software greatly facilitates device setup.
