IEC 62271-100 earth system improvement
Dear Standardization specialist
I heard that Standard is getting updated for the solidly earth system for SC test duties. It would define the additional test requirement for solidly earth system during 100% rating of symmetrical earth fault (TD100S) and asymmetrical earth fault (TD100a).
Could you please confirm & share what those new TD100S & TD100a cover as specific testing requirements?
