IEC 61869-1:2023 is the latest international standard that defines general requirements for instrument transformers intended for high-voltage applications. As a "Product Family" standard, it serves as the foundational document that must be used alongside specific product standards (like Part 2 for current transformers or Part 3 for inductive voltage transformers) to ensure equipment safety and reliability. Scope and Application

This standard is applicable to newly manufactured instrument transformers with analogue or digital secondary signals used for measuring, protection, and control.

Voltage Levels: Nominal voltages higher than 1 kV AC or 1.5 kV DC.

Frequency Range: Rated frequencies from 15 Hz to 400 Hz, as well as DC applications.

Output Types: Covers both traditional analogue outputs and modern digital interfaces. Core Technical Requirements

The IEC 61869-1 framework establishes high-level technical and conformity criteria that all instrument transformers must meet:

Performance Criteria: Defines permissible error limits, including accuracy class, ratio error, and phase angle displacement.

Environmental Conditions: Specifies requirements for both normal and special service conditions, including ambient temperature, altitude impacts, and vibration resistance.

Design & Construction: Outlines standards for materials, insulation (liquid, gas, or solid), earthing, and mechanical strength.

Safety: Includes rigorous requirements for fire hazard protection, internal arc fault protection, and corrosion resistance. The IEC 61869 Series Structure

The series was created to replace the older IEC 60044 standards, moving toward a more modular structure. A full standard for a specific product is composed of Part 1 (General Requirements) plus the specific part for that device. Iec 61869-1 Pdf

What is IEC 61869-1?

IEC 61869-1 is the international standard titled “Instrument transformers – Part 1: General requirements.” Published by the International Electrotechnical Commission (IEC), this document serves as the umbrella specification for all instrument transformers.

It replaced the older IEC 60044 series (which covered traditional CTs and VTs) and the IEC 60044-7 and -8 (for electronic transformers). The 61869 series harmonizes requirements for both conventional and emerging technologies into a single, coherent framework.

Key Update Note: 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.

Tests — type and routine

• Type tests (design verification): Performed on a sample or prototype to verify design. Typical type tests:
  • Insulation tests (power-frequency withstand, partial discharge, impulse/lighting impulse).
  • Temperature-rise test.
  • Accuracy tests across rated ranges and burdens.
  • Short-time thermal and dynamic tests (for CTs).
  • Electromagnetic compatibility and noise when applicable.
  • Dielectric tests after humidity or pollution tests where specified.
• Routine tests (each production unit): Ensure each manufactured unit meets basic safety and functional requirements. Typical routine tests:
  • Visual inspection and dimensional checks.
  • Ratio and polarity/phase check.
  • Insulation resistance or applied voltage test at a specified lower level than type test.
  • For CTs, transformation ratio and secondary circuit open-circuit/ short-circuit checks as applicable.
• Additional tests: Special tests may be required per product family (e.g., combined transformers) or by national/regulatory rules.

Relationship with Other Parts of IEC 61869

The “-1” in the title signifies that this document is always used in conjunction with a product-specific part. For example:

| Standard | Title | Use Case | | :--- | :--- | :--- | | IEC 61869-1 | General requirements | Always applicable | | IEC 61869-2 | Additional requirements for CTs | Current transformers | | IEC 61869-3 | Additional requirements for VTs | Voltage transformers | | IEC 61869-9 | Digital interface for ITs | Merging units & IEC 61850 |

You cannot certify a transformer based on Part 1 alone; you must also meet the relevant product-specific part.

3. Insulation and Dielectric Requirements

This is a critical section for safety. It details power-frequency withstand voltage, lightning impulse tests, and partial discharge limits. The standard ensures that transformers can survive overvoltages without failing catastrophically.

Using the PDF Effectively

1. Always refer to the latest edition – As of 2025, the valid version is Ed. 2.0 (2020) with possible amendments. Earlier editions (Ed.1 – 2007) are obsolete.
2. Cross-reference with part-specific standards – For example, IEC 61869-2 covers CTs, IEC 61869-3 covers inductive VTs. Part 1 is the umbrella document.
3. Compliance checklist – Use the PDF’s Annex A (normative) to verify all routine tests before accepting new equipment.

Conclusion

The IEC 61869-1 PDF is far more than a digital document—it is the foundational reference for safety, reliability, and interoperability in instrument transformers. Whether you are designing a new substation, testing equipment in a lab, or writing a tender for a renewable energy project, this standard ensures that all stakeholders operate from a single, trusted source of truth.

Always ensure you have the latest edition (with amendments) from an authorized distributor. The small upfront cost of the official PDF prevents costly misapplications, legal liabilities, and safety failures in the field.
