4.3 Personal Computer Interface
The relay can be operated from a personal computer using an RS232C port on the front panel.
On the personal computer, the following analysis and display of the fault currents are available in
addition to the items available on the LCD screen.
•
Display of current and voltage waveforms: Oscillograph
display
•
Symmetrical component analysis:
On arbitrary time span
•
Harmonic analysis:
On arbitrary time span
•
Frequency analysis:
On arbitrary time span
For the details, see the separate instruction manual "PC INTERFACE RSM100".
4.4 Relay Setting and Monitoring System
The Relay Setting and Monitoring (RSM) system is a system that retrieves and analyses the data
on power system quantities, fault and event records and views or changes settings in individual
relays via a telecommunication network using a remote PC.
Figure 4.4.1 shows the typical configuration of the RSM system via a protocol converter G1PR2.
The relays are connected through twisted pair cables, and the maximum 256 relays can be
connected since the G1PR2 can provide up to 8 ports. The total length of twisted pair wires should
not exceed 1200 m. Relays are mutually connected using an RS485 port on the relay rear panel and
connected to a PC RS232C port via G1PR2. Terminal resistor (150 ohms) is connected the last
relay. The transmission rate used is 64 kbits/s.
