Product Detail

Brand:Wapower

Description:Three phase isolation transformer is mainly used in low voltage distribution system, isolating load from power supply. Distribution system is divided into TN, TT and IT. The first T indicates that the neutral point of power transformer is directly grounded. I indicates the neutral point of power transformer is non-grounded(or grounded through high impedance). The second T indicates that the case of electrical equipment is directly grounded, but have no connection with the power grid of ground system. And N indicates that the case of electrical equipment is connected with the grounded neutral wire of system. TN system: the neutral point of power transformer is grounded and the case of equipment is partially connected with neutral wire. TT system: the neutral point of power transformer is grounded and the case of equipment adopts protection grounding. IT system: the neutral point of power transformer is non-grounded but the case of equipment adopts protection grounding. In the IT system, isolation transformer can prevent electric shock, protect the connected equipment from insulation damage and make the neutral point isolated.
