The leakage protector of our company not only has the function of slow change leakage protection of general leakage protector, but also adopts the invention patent double discrimination leakage protection technology, that is, the phase detection technique is first used to detect the sudden leakage signal in the power network without dead zone at 360 °. At the same time, the phase line load current in the power network is detected. When a sudden leakage occurs in the power network and reaches the operational value, if the phase line load current in the power network changes (increase or decrease) at the same time, it means that the equipment with leakage in the power network is on or off. Then the protector does not act; on the contrary, it is believed that the human body is electrocuted, and the protector trips the protection, which separates the human body electric shock protection from the switching or cutting operation of the equipment with leakage, which not only ensures the safety of the human body's electric shock, but also greatly improves the power grid.
