    AC or DC transients, high ambient temperatures, and high air humidity always have a certain likelihood of causing damages. Delivered equipment undergoes extensive testing and quality control in the ABB manufacturing program. All types of IEDs and their integral components have been subject to extensive laboratory testing during the development and design work.

    The periodicity of all tests depends on several factors, for example the importance of the installation, environment conditions, simple or complex equipment, static or electromechanical IEDs, and so on. The normal maintenance praxis of the user should be followed. However ABB proposal is to test: Every second to third year...
