Software
SOFTWARE
Protection Relays and Alarm Systems are supplied with
free software. The software simplifies programming and
allows the user to save setpoint files and reuse them for
similar applications.
The software gives the ability to change parameters and
see the impact on the protection time current curves. It
also allows another device curve to be entered to view
simple coordination.

Features
Provides the ability to configure and monitor Modbus
networks. The features include data logging, real-time data
monitoring and fault and event monitoring. Devices can be
added and configured manually or the software can scan
an existing network to identify devices which can be used
as is or reconfigured by the user. Setpoints for each device
can be uploaded and downloaded for easy monitoring and
reconfiguration.

1. Only the load carrying conductors pass
through the center of the CT. This means
L1 + N for 1-phase and L1+ L2 + L3 for
3-phase.
2. The power conductors pass through
the center of the CT and are preferably
bound together to keep the conductors
uniformly spaced.
3. The power conductors pass perpendicular
to the CT and, where practical, continue
perpendicular to the CT on both sides of
the CT for 3”.
4. The power conductors should not be
installed in a way that allows them to run
along the side edges of the CT.
5. Where practical, locate the CT away
from noise-generating devices such as
transformers, frequency converters, etc.

Description
A variety of protection relay retrofit adapter plates are
available for the products listed below. These adapter plates
simplify the process of updating electromechanical or poorly
functioning existing relays. Consult factory if you have a
specific product to replace that is not featured. Adapters are
available in either plate style for panel mounting or drawout
style depending on the relay being replaced.
Motor, feeder and ground-fault protection upgrades are
available for electromechanical or solid state relays that are
nearing the end of their life.
