An earthing system is characterized by two letters. 1. The first letter indicates the connection of the transformer's neutral: • T: The transformer's neutral is connected to earth. • I: The transformer's neutral is isolated (or impedance-connected) from earth. 2. The second letter indicates how the exposed conductive parts of the installation are connected. • T: The exposed conductive parts are connected to earth. • N: The exposed conductive parts are connected to the neutral, which is itself connected to earth. #electrical training #vocational training #training courses #electrical certification
