The ground leakage current is made up of several contributions and depends on various system configurations, including:

RFI filtering.
Motor cable length.
Motor cable shielding.
Drive power.

Motor cable length

Leakage current

Illustration 44: Influence of the Cable Length and Power Size on Leakage Current, Power Size a > Power Size B

The leakage current also depends on the line distortion.

THDv=0%

THDv=5%

Leakage current

Illustration 45: Influence of Line Distortion on Leakage Current

If the leakage current exceeds 3.5 mA, compliance with EN/IEC 61800-5-1 (power drive system product standard) requires special
care.
