Overview
EN 60076-3:2013/A1:2018 (adoption of IEC 60076-3:2013 with Amendment A1) is the European standard that defines insulation levels, dielectric tests and external clearances in air for power transformers. Approved by CENELEC in April 2018, this amendment clarifies test requirements and updates specific test and clearance provisions for manufacturers, utilities and test laboratories involved in transformer design, verification and acceptance.
Key topics and requirements
- Insulation levels - Establishes how transformers are categorized and tested according to the highest-voltage winding (Table 1 title revised to reflect U of the highest voltage winding).
- Dielectric tests - Defines routine, type and special dielectric testing methods. Amendment A1 updates the routine test for lightning impulses:
- Chopped-wave lightning impulse (LIC) is required on all line terminals with U > 170 kV (Clause 7.3.3.1).
- Standard lightning impulse (LI) is required on line terminals with U ≤ 170 kV; purchasers may request LIC for these as well.
- Line terminal AC withstand (LTAC) - Administrative correction noted (French language correction referenced).
- External clearances in air - Clearances limits revised in the amendment (E.4: change from “≤ 750 kV” to “< 850 kV” in the applicable paragraph).
- Test procedure coordination - The standard recommends that test connections and procedures be discussed at contract or design-review stage, especially for complicated transformers, non-uniformly insulated windings and induced-voltage or impulse arrangements (C.1).
Note: Test voltages and detailed procedures are specified within the full standard and supporting tables (e.g., Table 2 referenced for test voltages).
Practical applications
- Specifying acceptance and routine tests in procurement contracts for power transformers.
- Guiding design decisions for insulation coordination and physical clearances in air.
- Providing test laboratories and manufacturers with the required dielectric test methods and criteria for type and routine testing.
- Helping utilities, EPCs and certification bodies ensure safety, compliance and interchangeability across installations and the European market.
Who should use this standard
- Transformer manufacturers and design engineers
- High-voltage test laboratories and quality inspectors
- Utilities and grid operators specifying or accepting transformer equipment
- Procurement teams and contract drafters
- Certification bodies and compliance assessors
