CE Marking (CE Mark) for Low Voltage Electrical Equipment ... "Electrical Equipment" means any equipment designed for use with a voltage rating of between 50 and 1000 V for alternating current (A.C.) and between 75 and 1500 V for direct current (D.C.). Therefore, this Directive is called often "Low Voltage Directive" which applies to the vast majority of electrical equipment in everyday use.
Transformer Protection Application Guide2013-5-28 · current is limited to less than 10A. In a typical utility application, transformers are connected directly to ground, but occasionally a small reactor is placed in the transformer neutral that limits ground fault current to approximately the same level as three phase faults. In this example system, the protection scheme described
