W artykule zawarto porównanie wybranych właściwości silnikowych filtrów pasywnych LC, ograniczających wysokoczęstotliwościowe prądy doziemne płynące przez pojemności pasożytnicze kabli silnikowych i silników. W badaniach oceniających efektywność filtracji prądów doziemnych uwzględniono takie kryteria jak: napięcie względem ziemi punktu neutralnego uzwojeń stojana silnika, oraz napięcie fazowe zasilania przemiennika częstotliwości.

In the article basic features' comparison of different kinds of passive LC motor filters, utilized in order to reduce inverter's the differential and common voltage in the frequency converters drives, is presented. Filters' examinations were prepared for non-grounded power supply of electrical drives (IT mains) where parasitic ground capacitances of a screened motor cable have significant value. Filters were compared under following criteria: voltage of stator windings neutral point to grounded motors cover, high frequency parasitic current in PE conductor, value of frequency converter phase-ground and value of motor phase-phase voltage. Examinations were made for unscreened and screened motor cables.
