Technical explanation
 is the difference between zero sequence transformer and residual current transformer? What is the difference between zero sequence transformer and residual current transformer?
The working principle of zero sequence current transformer and residual current transformer is similar, very
Many people default that the zero sequence current and the residual current are the same, in fact, there is a difference between the two
Yes, the objects protected by the first constitution are different.
The zero sequence current protection is the current formed by the three-phase unbalance or lack of phase,
Therefore, the current is generally very large, so the transformer usually outputs 5A or 1A
The way, the main work is similar to the protective strider transformer. Zero sequence
Strike current transformer generally sets 3 phase wires without neutral wire or ground wire.
The remaining current transformers generally test residual current or wire
The leakage current of the circuit, not the zero sequence current or the lack of phase current, so the remaining power
The current mutual inductance needs two wires to be covered with 4 wires, in addition to the 3 grain phase wires, the neutral wire or ground wire is also required
Set in and lose.
