Breaker Analysis

Options

The test system can be extended by the addition of optional components such as voltage sources and can be customized by the inclusion of customer-specific connection panels. 

Evaluation Unit

 19" industrial standard, integrated in the front panel of the cabinet, consisting of:

  1. Industrial PC (Windows XP operating system, pre-installed user software)
  2.  17" TFT monitor
  3. industrial rackmount keyboard/mouse unit

 height: 13 HU 

Sources

The additional current and voltage sources can be used to supply external actuators such as spring-tensioning motors, release and operating coils or heating systems.

The outputs of all sources are located on a connection panel and external sources can be looped in if required. The sources are released via integrated power contactors.

All sources can be controlled and monitored either manually or automatically by the test system. The desired values are set automatically in accordance with the parameters of the test plan. The sources can be controlled either statically or dynamically, e.g. to test overcurrent or undervoltage releases.

 -
Patch panel on the cabinet front  2 x 108-pole  The patch panel is used to allocate the inputs and outputs of the test system to the appropriate connection leads of the test object. The allocation is made using industrial plug connectors with the appropriate wiring (allocation) inside the plug housing.  5 U
Custom connection panel on the cabinet front    Connection panel for connecting the measurement and output signals for coil control, for example, the main and auxiliary contacts and analog or incremental sensors. Connections are made using safety banana sockets and multi-contact sensor sockets. The exact specifications are agreed with individual customers.  5 U
Binary I/O extension  24 V to 300 VDC  Addition of:
12 universal binary inputs with a common ground
8 binary outputs		 - -
