The function of zero sequence current transformer
When an electric shock or leakage fault occurs in the circuit, the protection acts and the power supply is cut off.
Conditions of use for zero sequence current transformers
A current transformer can be installed on each of the three-phase lines, or three-phase conductors can be passed through a zero-sequence current transformer together, or a zero-sequence current transformer can be installed on the neutral line N to use it to detect three phases. Vector sum of current.
