Zero-sequence current transformers are also called residual current transformers, ground current transformers or leakage current transformers. They are usually used in power fire protection equipment. When the power system generates zero-sequence grounding current, it is used in conjunction with the relay protection device for pre-protection or monitor. The basic principle of the zero sequence current…
Current transformer is an electronic component that can convert electrical energy into magnetic energy, store it under appropriate conditions, and release it and then convert it into electrical energy. The most important role of inductor is electromagnetic conversion. All electrical conductors (transmission lines) will cause electromagnetic fields when passing current. When the electrical conductors (transmission lines)…
[vc_row][vc_column][vc_column_text]Reactors are also called inductors. When an electrical conductor is connected to the power supply, it will create a magnetic field in a certain space it occupies. Therefore, all electrical conductors that can carry current are inductive in a general sense. However, if the power supply is long, the inductance of the electrical conductor is…
Reactors are also called inductors. When an electrical conductor is connected to the power supply, it will cause an electromagnetic field in a certain space occupied by it. Therefore, all electrical conductors that can carry current are inductive in a general sense. The inductive load must absorb the active current and reactive current of the…

Working principle of current transformer The working principle of the current transformer is similar to that of the transformer. The most critical difference with the voltage transformer is that under normal operation, the pressure drop on the primary and secondary windings is not large, which is equivalent to a transformer with a short-circuit fault condition.…
