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.
