EMC is involved!
After having completed this workshop you will be more able to understand the ‘inexplicable’ phenomena and to realize reliable installations.
Every installer is familiar with ‘mysterious’ phenomena, like failing or defective inputs, conductors under unexpected voltage, time-out messages on communication links etc. Vague failures causing people to conclude that EMC is involved. What can be done? Terms like ground loops, potential balancing, EMC grounding, shielding, higher harmonic, ESD, are all related to these phenomena. Is there a univocal approach that can solve this kind of failures or prevent them from happening?
The frequency inverter is often the cause of the defect. And because of power electronics innovations the risk of failure is only increasing. As a supplier of frequency inverters SEW-EURODRIVE organizes workshops free of charge, where the settings of different kinds of failures are elucidated. Participants are in particular taught about the practical measures that can be taken regarding installations in order to avoid the spreading of interference. How can an installation be arranged in such a way that it is sufficiently immune to ever-present interfering fields? By performing a practical measurement we will show the effects of certain measures.
A related subject that will be dealt with, is the application of frequency inverters at spots where an earth leakage circuit breaker is necessary, which is often the case in workshops, schools and mobile installations.
