These tests are performed only upon agreement between the manufacturer and the purchaser. Chopped impulse voltage withstand tests. Multiple-day environmental or corrosion tests. Seismic qualification tests.

A notable feature of the latest edition is its coordination with digital substation standards. Characteristics of the are standardized in IEC 61869-9 , which applies the IEC 61850 horizontal standard series covering communication networks and systems for power utility automation. This integration reflects the industry's shift toward digital substations and process bus architectures.

Addresses safety considerations in the design and application of instrument transformers.

Verifies the insulation integrity under normal operating frequencies over a short duration. Iec 61869-1 Pdf

The is applicable to newly manufactured instrument transformers intended for use where the nominal voltage of the system exceeds 1 kV AC or 1.5 kV DC. The transformers can be used with electrical measuring instruments or electrical protective devices, operating at rated frequencies from 15 Hz to 400 Hz, or for DC applications.

: The latest 2023 edition specifically covers high-voltage (HV) applications where the nominal voltage is > 1 kV AC or > 1.5 kV DC.

The is an indispensable resource for anyone working with instrument transformers in modern power systems. As the foundational document of the IEC 61869 series, it establishes the universal requirements that all instrument transformers must meet—covering everything from ratings and design to testing and digital interfaces. These tests are performed only upon agreement between

The 2023 edition is a that merges content from IEC 61869-6:2016, expands the frequency range from 100 Hz to 400 Hz, adds DC applications, introduces commissioning tests, adds four new annexes, and updates accuracy requirements for harmonics and anti-aliasing filters.

The 2023 edition adds a new clause specifically for to be performed after installation on site.

(Edition 2.0) is the current valid edition. The 2007 edition has been superseded and withdrawn. Seismic qualification tests

For each specific transformer type, the complete product standard consists of (e.g., IEC 61869-2 for current transformers, IEC 61869-3 for inductive voltage transformers, etc.).

The most current version widely referenced today is IEC 61869-1:2007 + AMD1:2021 (Edition 2.1). Any reliable IEC 61869-1 PDF should reflect these amendments.
