380VAC three phase 300A emi filter for variable frequency drive VFD
EMI Power Line Filter from the LC low-pass passive network
components.It uses principles of impedance mismatch,so that by
the attenuation of electromagnetic interference signals.
Filter filtering effect depends on the extent of impedance
mismatch,the greater the impedance difference, the better the
filter. For example,to get better results, for low-impedance power
supply side, should be accompanied by a high input
impedance of the filter;pairs of high input impedance of the load
side, then the filter with low output impedance.

Leakage current
Leakage current: at a given voltage and frequency, the current flow
between the filter-phase line or the midline and ground.
Under normal circumstances, leakage current from the grounded
capacitors (Y capacitor) is caused due to security
considerations, a variety of different testing standards for
various types of equipment, leakage current from the strict 1
imitations. In particular, medical equipment, in choosing a filter,
be sure to take full account of the leakage current.
Leakage current typically 250VAC 50HZ, below the ambient
temperature is 20°C measured. Works as follows:
