2.17 Additional Functions
The additional functions of the 7SD610 differential protection relay include:
• Commissioning tool,
• Processing of messages,
• Processing of operational measured values,
• Storage of fault record data.
2.17.1 Commissioning aid
2.17.1.1 Function Description
There is a comprehensive commissioning and monitoring tool that checks the commu-
nication and the whole differential protection function. The WEB-Monitor is an integral
part of the device. The respective online-help is available with DIGSI on CD-ROM or
via the internet at www.siprotec.de.
To ensure a proper communication between the device and the PC browser, the trans-
mission speed of both must be equal. Furthermore, the user must assign an IP
address so that the browser can identify the device.
The WEB-Monitor also enables the user 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.
If the device is equipped with an EN100 module, operation with DIGSI or the WEB-
Monitor is also possible via Ethernet. All that has to be done is to set the IP configura-
tion of the device accordingly. Parallel operation of DIGSI and WEB-Monitor via differ-
ent interfaces is possible.
WEB-Monitor The „WEB-Monitor“ is a comprehensive commissioning and monitoring tool which
enables to clearly display the differential protection communication and the most im-
portant measured data using a PC with a web 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
please refer to the online help for the „WEB-Monitor“.
This tool enables to graphically display, for instance, the currents, voltages (if connect-
ed to the system) and their phase angles for all devices of a differential protection
system on a PC. In addition to phasor diagrams of the measured values, the numerical
values as well as frequency and device addresses are indicated. Figure 2-106 shows
an example.
Additionally the position of the differential and restraint values can be viewed in the
tripping characteristic.
