Never. While some sites (like scribd or docplayer) might have older drafts, those hosted on sketchy .ru or .cn domains are almost always infected with malware or are poor OCR scans missing critical tables.
If you represent a legitimate training organization or a testing lab, you can write to the IEC or your local standards body requesting a review copy for educational purposes. This is a long shot but possible for non-profits.
The search for “iec 61869-1 pdf free download” is natural, but the golden rule is this: Never compromise safety for cost. The IEC 61869 series is the backbone of modern substation safety. Using an illegal, outdated, or corrupted copy puts lives and equipment at risk.
