Power Quality and EMC

Lemcko specializes in research on power quality, high frequency power quality and EMC.

The research on high-frequency power quality (2 - 500 kHz) includes:

• Measurement methods for emission and immunity between 2 and 500 kHz
• Emission problems caused by switching harmonics
• Influence on network communication (power line communication)
• Measurement of grid impedance 2 - 500 kHz
• Propagation of 2 - 5000 kHz signals in the grid

The research on EMC mainly focuses on power electronic applications:

• Influence of drives on EMC and bearing currents
• Influence of cables
• Influence of filters
• Shielding of electrical cabinets
