What is Low Voltage Earthing Systems Explained about?

There are three main earthing systems used in low voltage electrical installations: 1. Unearthed or impedance earthed neutral system (IT) where the neutral point is unearthed or connected to earth via a high impedance and exposed conductive parts are interconnected and earthed. 2. Solidly earthed neutral system (TT) where the neutral point is directly earthed and exposed conductive parts are interconnected and earthed. 3. Neutral earthing system (TN) where the neutral point is directly earthed and exposed
