Tests complying with IEC 62271-202

Betonbau has been testing accidental arcing security in transformer stations since 1974 on neutral high-power test fields, initially in accordance with PEHLA directives and, since 1995, in compliance with IEC 61330

Betonbau conducted over 250 success trials on approx. 60 test dates in the period from 1974 to 2005.

Test conditions have become so strict under the new IEC 62271-202 that new accidental arcing tests need to be conducted.

Betonbau has taken timely action in this respect and compiled an ambitious catalogue of measures in which tests complying with IEC 62271-202 are taken into consideration and conducted.
