If you work for an engineering firm or study at a university, check your institutional library. Most engineering organizations subscribe to databases like IEEE Xplore, IHS Markit, or Techstreet, allowing you to download the PDF legally for free. Final Thoughts
applies to new inductive VTs used with measuring instruments and protective devices at frequencies from 15 Hz to 100 Hz. This standard also supersedes the previous IEC 60044-2.
You can find and purchase official PDFs from several trusted sources.
Connects directly to for digital interface characteristics.
The International Electrotechnical Commission (IEC) structured this standard series to replace the aging, standalone IEC 60044 series. Instead of scattering duplicated requirements across separate documents, the modern IEC 61869 architecture splits technical specifications into two distinct tiers: iec 618691 pdf best
If you’ve landed here searching for , you’re likely working with instrument transformers — current transformers (CTs), inductive voltage transformers (VTs), or capacitor voltage transformers (CVTs). And you need the official standard, fast.
The 2023 edition introduced optional (WB0 to WB4) to address harmonics in modern grids: WB0 : Up to 13th harmonic. WB1 : Up to 3 kHz.
: Agreed upon between manufacturer and purchaser (e.g., internal arc fault).
Baseline performance requirements up to 1,000 meters above sea level, including necessary correction factors for dielectric strength at higher altitudes. If you work for an engineering firm or
Impulse voltage tests, temperature rise tests, short-time current withstand tests.
Instrument transformers according to new IEC standards ... - ABB
Historically, current transformers were governed by IEC 60044-1, and voltage transformers by IEC 60044-2. The IEC consolidated and modernized these older standards into the unified IEC 61869 family. Part 1 serves as the foundational document, while subsequent parts (like Part 2 for CTs and Part 3 for VTs) build upon these basics with specific technical requirements. Key Sections Covered in the Standard
Tightness requirements for oil-immersed or gas-insulated ( SF6cap S cap F sub 6 This standard also supersedes the previous IEC 60044-2
: Requirements for Low Power Instrument Transformers (LPITs) are now integrated into Part 1.
A single general requirements part simplifies the application of rules across different transformer types.
Whether you are an electrical engineer, a project manager, or a compliance officer, finding the most current, authentic, and usable version of these standards—specifically in PDF format—is crucial for project success. This guide explains the full scope of the IEC 61869 series, provides the official channels for obtaining the highest quality PDFs, and details the best practices for implementing these standards in your testing and commissioning workflows.
