20Hz Injection Kit Monitoring System
Signals & Systems India Private Limited
The Display used to monitor the 20Hz and 50Hz current passing through NGT transformer. This could help to monitor the stator earth fault and could record the current every minute. The current shall be displayed in milliamps for both 20Hz and 50Hz. If an earth fault occurs in the generator star point, the 20 Hz voltage drives a current through the fault resistance. The current can be measured using clamp-on CT which would be clamped between load resistor and NGT. It gives an indication of the current values are lower or higher than the set threshold.

IRIG-B TTL TO RS485 Converter
SPC - INS - 1010
Signals & Systems India Private Limited
The IRIG-B TTL signal is a time synchronization protocol that can be transmitted up to 50m maximum using coaxial cable. So the relay which is to be received the IRIG-B TTL signal may be far away from the IRIG-B source. The relay may be not able to synchronize with the GPS. To avoid such an incident in the field, some of the relays have provision to receive IRIG-B RS485 signal. The IRIG-B RS485 signal can able travel up to 1200m without any booster. All Time source equipment may not be supplied with IRIG-B RS485 signal output. The converter will act as a bridge between GPS Time source and Relays for time synchronization.

20Hz Generator
Signals & Systems India Private Limited
In order to implement a 100 % stator earth fault protection based on subharmonic injection, a 20Hz voltage is injected into the generator star point. The 20-Hz generator SGEN-1001 is used in combination with the Band Pass Filter SBPF-1001 in the Stator Earth fault protection. The injection can be performed by connecting the SGEN-1001 and the SBPF-1001 to the load resistor of an earthing or neutral transformer. If an earth fault occurs in the generator star point, the 20 Hz voltage drives a current through the fault resistance. From the driving voltage and the fault current, the protective relay determines the fault resistance.
