It seems you're looking for the IEC 61869 series (instrument transformers), possibly with a typo in the number ("618691" instead of 61869), and the phrase "best — deep feature" suggests you want the most comprehensive PDF that explains deep technical features.

Here’s what you need to know:

1. Correct Standard: IEC 61869 is the series for instrument transformers (current and voltage transformers), replacing the older IEC 60044 series. It includes parts like:

   • 61869-1: General requirements
   • 61869-2: Additional requirements for current transformers
   • 61869-3: Inductive voltage transformers
   • 61869-9: Digital interface for instrument transformers
   • 61869-15: Low-power passive voltage transformers

2. "Best PDF with deep features" – If you want a free, detailed technical deep dive:

   • No free full PDFs of the copyrighted IEC standard are legally available.
   • However, application guides from manufacturers (like Siemens, ABB, GE, Arteche) often explain deep features (LPIT, merging units, accuracy classes, transient performance, digital substation integration) in more practical detail than the standard itself.

3. Recommended free resources for deep features:

   • IEC 61869-9 and 61869-15 – These cover the deepest new features: digital output, sampling rates, time sync, and compatibility with IEC 61850.
   • Search for: "IEC 61869-9 application guide PDF" or "Low Power Instrument Transformer (LPIT) technical paper"
   • Manufacturer whitepapers (e.g., "Understanding IEC 61869-15 for digital substations") provide practical "deep feature" explanations.

4. Where to obtain the official PDF:

   • IEC Webstore (paid, ~200–400 CHF per part)
   • Techstreet, ANSI, or national standards bodies (e.g., BSI, DIN)

If you clarify which specific part of IEC 61869 and what "deep feature" (e.g., transient performance, digital output, accuracy class X, PX, TPY, or LPIT) you need, I can point you directly to the best technical guide or paper.

8) Quick checklist before download/purchase

• Confirm you have the correct part (–1).
• Confirm the latest edition/year and any amendments.
• Choose official/licensed source.
• Ensure file format is PDF and metadata matches seller listing.
