What is BS EN 61251 – AC voltage endurance evaluation about?
BS EN 61251 covers insulating materials and systems. BS EN 61251 is a European Standards that deal with evaluation and qualification of electrical insulating materials and systems that protect the materials through which electric current flows. BS EN 61251 describes many factors involved in voltage endurance tests on electrical insulating materials and systems. It describes the voltage endurance graph, lists test methods illustrating their limitations, and gives guidance for evaluating the sinusoidal a.c. voltage endurance of insulating materials and systems from the results of the tests.
