IEC 62271-100 earth system improvement

[Esperanto]

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?

Best regards

Hello Esperanto, 

Those new articles you refer to are still at project level and didn't result in any country publication yet.

@coline , would you be involved in this redaction?

Hello all, Hello @Esperanto ,

I have been working indeed within CEN TC99999 - WS 3 on those two articles.

We are close to first draft publication, in coming weeks.

As A Specifier Premier plus, Espé, I can share with you enclosed last version: However, please don't disclose it before draft official publication.

By The Way, I would be interested in your own comments about both those articles😁

Best regards
