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.
This part applies to newly manufactured instrument transformers (current, inductive voltage, capacitor voltage, electronic, etc.) used for electrical measurement and protection at frequencies from 15 Hz to 100 Hz.
IEC 61869-1 serves as the foundational standard for the IEC 61869 series. It outlines the general requirements, definitions, and testing protocols for instrument transformers, which include Current Transformers (CTs) and Voltage Transformers (VTs).
This standard supersedes the older IEC 60044 series, modernizing the requirements to account for new technologies, particularly electronic (digital) instrument transformers.
Since the document itself cannot be provided, the following is a technical summary of the standard's scope and significance within the power systems industry.

Whether you are a substation engineer, a manufacturer, or a student, understanding this standard is essential for ensuring the accuracy and safety of electrical measurement and protection systems. 1. What is IEC 61869-1?
The standard establishes the core principles for newly manufactured instrument transformers used with electrical measuring instruments or protective devices. It is designed to be read in conjunction with specific standards (like IEC 61869-2 for current transformers or IEC 61869-3 for voltage transformers). IEC 61869-1:2007 - | Standards Council of Canada
If you are a student or professor, check your university’s library portal. Many technical universities subscribe to IEC Webstore or standards databases like IHS Markit, TechStreet, or Perinorm. You can download a genuine PDF for free through your institutional login.
Let’s address the elephant in the room. The official IEC documents are expensive. A single copy of IEC 61869-1 can cost anywhere from 200 to 400 CHF (Swiss Francs), which is roughly $220 to $450 USD. For a student or a small business in a developing nation, this price is prohibitive.
This high cost drives thousands of searches every month for phrases like:
