Additional requirements for low-power instrument transformers 4. Legitimate Access vs. "Free Download" Risks
: Many public libraries, universities, and research institutions offer free access to a wide range of standards, including IEC standards, through their subscriptions to standards databases.
Before diving into how to access the standard, it's important to understand what you would be accessing. IEC 61869-1 is the first part of the IEC 61869 series, which is an international standard for instrument transformers. It has been officially adopted by numerous national bodies, such as the British Standards Institution (BS EN IEC 61869-1:2024), the German Institute for Standardization (DIN EN IEC 61869-1), and the Canadian Standards Association (CSA C61869-1).

Given the variation, it is highly recommended to compare prices across these official vendors before making a purchase.
By the end of the week, the photocopy had passed hands a dozen times. Drafted notes grew into a portable binder of field fixes and clarifications—the kind of pragmatic supplement no standard could predict. Among those handwritten margins were warnings and improvements: a note on avoiding brittle connector housings in cold snaps, an addendum about mounting orientation, a sketch showing a safer test-point layout.
Almost every country has an NSB that sells international standards. Examples include: Before diving into how to access the standard,
: General requirements for all instrument transformers.
In the modern landscape of electrical power systems, ensuring accurate measurement, control, and protection is paramount. The serves as the foundational, general requirement document for instrument transformers. Whether you are an electrical engineer, a technician, or a procurement specialist, understanding this standard is crucial for specifying, testing, and utilizing voltage and current transformers safely and effectively.
When you purchase from the , you get:
IEC 61869-1 is just the first part of a much larger series. The that work together with Part 1 include a wide range of standards for different types of instrument transformers. Key standards in the series include Part 2 for current transformers , Part 5 for capacitive voltage transformers , Part 9 for digital interfaces for instrument transformers , and Part 15 for DC voltage transformers , among others.
While Part 1 sets the general rules, it acts as the umbrella document for the series. It references the following parts for specific applications:
