Poznámky redaktora
For example, the electrical conductor can the wall the switching cabinet.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. . This changing magnetic field produces an interference voltage.6.56 Table 3. 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. This often causes high currents flow through the cable sheaths. Electrostatic discharges (ESD) Static converters Switching high-voltage networks Devices equipped with clock frequency generators (PCs, PLCs, etc. • Inductive coupling: A variable current flow through the housing, the cable gland and the cable screening generates magnetic field. One example would motor with frequency converter. We differentiate between • Galvanic coupling: Galvanic coupling connectors occurs mainly the earth circuit.) Abrupt changes voltages and currents 3.3 Transmission Paths Coupling mechanisms with connectors: We define the term coupling the way electromagnetic interference influences (pre-assembled) connector
