Power transformers - Part 4: Guide to the lightning impulse and switching impulse testing - Power transformers and reactors

Gives guidance and explanatory comments on the existing procedures for lightning and switching impulse testing of power transformers to supplement the requirements of EN 60076-3. Also generally applicable to the testing of reactors (see EN 60289), modifications to power transformer procedures being indicated where required. Information is given on waveshapes, test circuits including test connections, earthing practices, failure detection methods, test procedures, measuring techniques and interpretation of results.

Transformateurs de puissance - Partie 4: Guide pour les essais au choc de foudre et au choc de manoeuvre - Transformateurs de puissance et bobines d'inductance

Donne des directives et des commentaires explicatifs sur les méthodes d'essais d'impulsions de choc de foudre et de manoeuvre existantes pour les transformateurs de puissance, afin de compléter les prescriptions de la EN 60076-3. Il est également généralement applicable aux essais des bobines d'inductance (voir la EN 60289): Les modifications aux méthodes des transformateurs de puissance sont indiquées, si nécessaire. Des informations sont données sur les formes d'onde, les circuits d'essai comprenant les connexions d'essai, les pratiques de mise à la terre, les méthodes de détection de défaillance, les méthodes d'essai, les techniques de mesurage et l'interprétation des résultats.
