Ecodesign of equipment for electricity distribution ...· Figure 10.1 depicts the electrical network in France. Dams and nuclear power and carbon plants generate electricity. At first it is sent through a step-up transformer, which increases the voltage level and sends the electricity to transmission lines. Electricity then is conveyed over long distances in high-voltage lines called HTB (400, 225, 90 and 63 kV) and managed by RTE.

Fundamentals of Power System protection by Y.G.Paithankar ...· 1.7.1 Current Transformer The current transformer has two jobs to do. Firstly, it steps down the current to such levels that it can be easily handled by che relay current cod. The standard secondary current ratings used in practice are 5 A and 1A. This frees the relay designer from the actual value of primary current.
