Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Powerline Telecommunications (PLT). The present document is part 1 of a

Introduction In order to study and co

21、mpare MIMO (Multiple Input Multiple Output) characteristics of the LVDN network in different countries, the STF 410 (Special Task Force) was set up. The present document is one of three parts of TR 101 562 which present the findings of STF 410 research. ETSI ETSI TR 101 562-1 V1.3.1 (2012-02)61 Scop

35、bbreviations apply: AC Alternating Current AMN Artificial Mains Network BCA Building I No point is connected with earth (isolation), except perhaps via high impedance. The second letter indicates the connection between earth and the electrical device being supplied: T Direct connection of a point wi

36、th earth; N Direct connection to neutral at the origin of installation, which is connected to the earth. 6.1.1 TN Networks In a TN earthing system, one of the points in the generator or transformer is connected with earth, usually at the star point in a three-phase system. The body of the electrical

37、 device is connected with earth via this earth connection at the transformer. Figure 2: TN Networks The protective earth (PE) is the conductor that connects the exposed metal parts of the consumer. The neutral (N) conductor connects to the star point in a three phase system, or carries the return cu

38、rrent in a single phase system. There are three variants of TN systems: TN-S, TN-C, TN-CS ETSI ETSI TR 101 562-1 V1.3.1 (2012-02)126.1.1.1 TNS PE and N are separate conductors that are only connected together near the power source. Figure 3: TN-S Network Separate protective earth (PE) and neutral (N

39、) conductors from transformer to consumer device, which do not connect after the building distribution point. 6.1.1.2 TNC A combined PEN conductor fulfils the functions of both a PE and an N conductor, but this type of installation is rarely used. Figure 4: TN-C Networks The combined PE and N conduc

40、tor are connected all the way from the transformer to the consuming device. 6.1.1.3 TNCS Part of the TN-C-S system uses a combined PEN conductor, which splits into separate PE and N lines. The combined PEN conductor typically occurs between the substation and the entry point into the building, and s

41、eparates in the service head. This system, which connects the combined neutral-and-earth conductor to real earth at many locations to reduce the risk of broken neutrals, is also known as “protective multiple earthing“ (PME) in the UK and “multiple earthed neutral“ (MEN) is the designation of Austral

42、ias system. ETSI ETSI TR 101 562-1 V1.3.1 (2012-02)13Figure 5: TN-C-S Networks Combined PEN conductor from transformer to building distribution point, but PE and N conductors separate in the fixed indoor wiring and have flexible power cords. 6.1.2 TT Network In a TT earthing system, consumer PE conn

43、ections are provided by a local connection to earth, which is independent from any earth connection at the generator. An advantage of a TT network is that there is no risk of a broken neutral. In locations where power is distributed overhead and TT is used, installation earth conductors are not at r

44、isk should any overhead distribution conductor be fractured by, say, a fallen tree or branch. TT earthing systems were unattractive for general use, before RCD times, due to their lesser ability to accept high currents in the event of a live-to-PE short circuit (in comparison to TN systems).However,

45、 residual current devices mitigate this disadvantage, making the TT earthing system attractive for premises where all AC power circuits are RCD-protected. Figure 6: TT Network ETSI ETSI TR 101 562-1 V1.3.1 (2012-02)146.1.3 IT Network In an IT network, the distribution system has no connection to ear

46、th at all, or it has a high impedance connection which is monitored by an insulation monitoring device. Environments supplied via engine-generators, e.g. laboratory rooms, medical facilities, construction sites, repair workshops, mobile electrical installations, etc., where there is an increased ris

47、k of insulation faults, often use an IT earthing arrangement supplied by insulation transformers. In order to mitigate the two-fault issues with IT systems, isolation transformers should either supply only a small number of loads each and/or be protected with an insulation monitoring device (general

48、ly used only by medical, railway or military IT systems, due to cost). Figure 7: IT Network When an isolation problem occurs, the power is not cut, but the monitoring system detects the current leakage through the high impedance and a warning light comes on to indicate that there is a problem. An as

49、signed technician has to then solve the problem. It is mandatory that he be available 24/7 as implied this grounding standard. If a second problem occurs with a stronger current leak to earth, where both Phase and separate earth and neutral cores thereafter in all internal wiring. Urban and suburban homes in the UK tend to have TN-S supplies, where the earth connection is delivered through the lead sheath of the underground lead-and-paper cable. Older homes, worldwide, especially those built before the invention of residual-current c
