Operation of Three-Phase Power System: 2 Ways | Electrical Engineering

There are two ways in which three-phase system can be operated and they are: 1. With isolated or free or ungrounded neutral  2. With grounded neutral. Way # 1. Ungrounded Neutral System: The 3-phase 50 Hz ac power systems with neutral earthed (or grounded) at every voltage level are used for generation, transmission, distribution and utilization of electrical power.
