Poznámky redaktora
. One example would motor with frequency converter. This changing magnetic field produces an interference voltage. This often causes high currents flow through the cable sheaths. • Inductive coupling: A variable current flow through the housing, the cable gland and the cable screening generates magnetic field.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.) Abrupt changes voltages and currents 3.6. We differentiate between • Galvanic coupling: Galvanic coupling connectors occurs mainly the earth circuit. Electrostatic discharges (ESD) Static converters Switching high-voltage networks Devices equipped with clock frequency generators (PCs, PLCs, etc.3 Transmission Paths Coupling mechanisms with connectors: We define the term coupling the way electromagnetic interference influences (pre-assembled) connector. For example, the electrical conductor can the wall the switching cabinet. Thus, line- conducted interference can transmitted. All earth wires pre-assembled cables are connected via common electrical conductors the earth potential and subsequently the PE.56 Table 3
