### VIDEO ### Perkongsian mengenai cara-cara Earth Fault dikesan dalam Protection System: 1. Residual Connection Current Transformers 2. Standby Earth Fault - Neutral to Earthing CT Connection 3. Core Balance CT or Zero Sequence CT 4. Metal Clad Frame Leakage Connection 5. Restricted Earth Fault Connection (REF) 6. Ground Fault or Neutral Displacement Over Voltage (59N) ### NOTA FREE/ FREE NOTES ### Link: https://shorturl.at/AFQ89 CORRECTION IN THE NOTES: For the last type of protection on 59N, there is a formula "Rp = Rs x N2". Whereby the 2 is supposed to be to the power of 2 or squared. ### NOTA FREE ###
