There are Three Types of Interference Generated by Explosion-Proof Frequency Converters

Table of Content [Hide]

    There are three types of interference generated by explosion-proof frequency converters, namely: conduction, electromagnetic radiation, and inductive coupling. Specifically for:

    ① Generate electromagnetic radiation to surrounding electronic and electrical equipment.

    ② Electromagnetic noise is generated in directly driven electric motors, causing an increase in iron and copper losses, which in turn generates heat and conducts interference to the power supply, which is then transmitted to other equipment in the system through the distribution network.

    ③ Explosion proof frequency converters induce coupling with adjacent lines, inducing interference voltage or current. Similarly, interference signals within the system interfere with the normal operation of explosion-proof frequency converters through the same pathway.
