7-5 Zero Phase Reactors
Interferences can also be suppressed by installing a zero phase reactor at the mains input or the
motor output of the drive, depending on where the interference is. Delta provides two types of zero phase
reactors to solve interference problems.
A. Casing with mechanical fixed part
This solution is for mains input/motor output side and can endure higher loading and be used at
higher frequencies. Higher impedance can be achieved by increasing the number of turns.

B. Casing without mechanical fixed part.
This solution has higher performance: high initial magnetic permeability, high saturation induction
density, low iron loss and perfect temperature characteristic. If it does not need to be fixed mechanically,
this solution is suggested
