You calculate the grid resistance (Rg) using the updated Schwarz or Laurent-Niemann formula from Clause 14. Then multiply by the grid current (Ig). If GPR exceeds the tolerable touch voltage, the design fails.
Absolutely. Clause 4 explicitly covers generating stations. However, pay special attention to section 15.9 on DC offset in fault currents, which is critical for inverter-based resources. ieee std 80 2013 pdf download work
While the PDF is ideal, other formats exist if you cannot obtain the PDF: You calculate the grid resistance (Rg) using the
