What is the working principle of phase protector?
The author：admin source： The date of：2019-04-20 04:03 sentiment：
The lack of protection principle: the three-phase wire around an iron core at the same time, phase equilibrium, magnetic flux of the core is 0, when the three-phase unbalance when the magnetic flux of the core is not 0. the same wound around the core of the detection coil generates electromotive force, after amplification processing contactor tripping protection control.
