IEEE 436 – IEEE Guide for Making Corona (Partial Discharge) Measurements on Electronics Transformers

Revision Standard – Inactive-Reserved.A uniform procedure for making corona (partial discharge) measurements by electrical means on electronic transformers is presented. Methods of applying voltage stress, the use of a sine-wave voltage to simulated dc and ac combinations, the types and limitations of voltage stresses encountered, and the acceptable limits of discharge pulse energy are included. Recommended test conditions and the need for negotiation of special tests are discussed. Test apparatus and calibration are described. The aim is to establish a common ground of understanding between transformer and systems design engineers and transformer manufacturers in the development of service and performance requirements.
