Introduction and Overview
In this way, status information,
alarms, trip information and
setpoints (e.g. overcurrent, phase
unbalance, overvoltage) increase
transparency in power distribution
systems, enabling these situations
to be dealt with quickly. A
communication host can send
short text messages to the cell
phones of maintenance personnel.
Prompt analysis of this data enables
targeted intervention in the process
and helps reduce system down
time.
Information for preventive
maintenance (e.g. the number
of operating cycles or hours)
enables timely personnel and
material scheduling, which
increases system availability and
helps prevent sensitive system
components from being damaged.
Communication helps provide
rapid and targeted information on
the location and cause of power
failures. The cause of the fault can
be determined by recording the
phase currents (e.g. trip as a result
of a short-circuit of 2317 A in phase
L2 on 08/27/2002 at 14:27). This
information can be used to quickly
rectify the fault and reduces
downtime for quicker recovery.
Measuring and communicating
power, power factor and energy
allows an even greater number
of applications. The availability
of power consumption data on a
targeted basis for business analysis
enables power profiles to be created
and costs to be clearly assigned.
In this way, energy costs can be
allocated and optimized by
balancing the peak loads.
WL Circuit Breakers—Modular and
Intelligent
Thousands of options with just a few
components: That's the WL. A new
generation of circuit breakers – from
200A to 5000A – with a modular
design to support every conceivable
application in power distribution
systems – cost effective and flexible,
its communication functionality
enables it to be integrated in
system solutions.
Cost Saving
Whatever the configuration, the
WL Circuit Breaker does the job
where it matters. Advantages
include simple retrofitting and a
compact design benefiting
everyone who uses WL Circuit
Breakers, whether in planning,
business, or whether they develop
or operate switchgear systems.
Easy Planning
The WL Circuit Breaker and EasyTCC
together provide a convenient
software package for coordinating
multiple circuit breakers.
System Solutions
By integrating WL Circuit Breakers
in a higher-level communication
system, they can be configured via
PROFIBUS, Ethernet or the Internet;
an integrated power management
system allows you to optimize
power distribution across the board.
