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