2.24.1 Commissioning Tools
2.24.1.1 Functional Description
The device is provided with a comprehensive commissioning and monitoring tool that
checks the communication and the whole system of the differential protection function.
The online help for this tool is available on CD-ROM together with DIGSI
®
, and in the
Web under www.siprotec.com.
To ensure a proper communication between the device and the PC browser, the trans-
mission speed must be equal for both. Furthermore, the user must set an IP address
so that the browser can identify the device.
Thanks to the „IBS-Tool“ the user is able to operate the device with the PC. On the PC
screen the front panel of the device is emulated, a function that can also be deactivat-
ed by the settings. The actual operation of the device can be now simulated with the
mouse pointer. This possibility can be disabled.
IBS-Tool The „IBS-Tool“ is a comprehensive commissioning and visualization tool which
enables the user to chart the communication and the most important measurement
data of the complete differential protection system on a PC screen by means of an In-
ternet browser. Measured values and the values derived from them are graphically
displayed as phasor diagrams. You can also view tripping diagrams. Scalar values are
shown in numerical form. For more details refer to the online help for the „IBS–Tool“.
This tool allows to illustrate the measured values, the currents, voltages (if connected
to the system) and their phase relationship for all devices connected to the differential
protection system. In addition to phasor diagrams, numerical values as well as fre-
quency and device addresses are indicated. Figure 2-184 shows an example.
Additionally, the position of the differential and restraint values can be viewed in the
pickup characteristic.
