Poznámky redaktora
Thus, line- conducted interference can transmitted. This often causes high currents flow through the cable sheaths.) Abrupt changes voltages and currents 3. This changing magnetic field produces an interference voltage.56 Table 3.6. One example would motor with frequency converter.5: Functional sources Non-functional sources Communications transmitters Automotive ignition systems Generators for industrial medical applications Fluorescent lamps Mobile phones Welding fixtures Radar position finding Connector contacts Material processing Relays and contactor coils Microwave ovens, etc. • Inductive coupling: A variable current flow through the housing, the cable gland and the cable screening generates magnetic field. We differentiate between • Galvanic coupling: Galvanic coupling connectors occurs mainly the earth circuit.3 Transmission Paths Coupling mechanisms with connectors: We define the term coupling the way electromagnetic interference influences (pre-assembled) connector. . Electrostatic discharges (ESD) Static converters Switching high-voltage networks Devices equipped with clock frequency generators (PCs, PLCs, etc. For example, the electrical conductor can the wall the switching cabinet. All earth wires pre-assembled cables are connected via common electrical conductors the earth potential and subsequently the PE
