7、is not part of IEEE P1775 Introduction Power Line Communication (PLC) technology has developed over a long period of time. As early as 1838 Edward Davy proposed remote electricity supply metering for the purpose of checking the voltage levels of the batteries at unmanned sites in the London-Liverpoo
8、l telegraph system. The first carrier current system for mains signaling was established in 1893 by the Swiss Electricity Board. The carrier frequency transmission of voice over power lines began in the 1920s. Due to low attenuation and low noise in the transmission lines at the carrier frequencies
9、(15 KHz 500 KHz), a distance of 900 km between transmitter and receiver could be attained with a power of 10 Watts. In 1930 Ripple Carrier Signaling was implemented in Germany over medium and low-voltage distribution power lines. Such systems typically operated in the frequency band 125 3000 Hz, so
10、a carrier signal propagated with low losses. Advances in communication technology in the late 1990s led to new research and development activities related to data communication through the power grid. Known widely as Power Line Communications (PLC), this technology is also named Broadband over Power
11、 Line (BPL), Power Line Telecommunication (PLT) and Power Line Technology (PLT). PLC created a mix of high expectations and concerns mainly due to perceived electromagnetic compatibility problems and absence of regulatory and standardization framework to address them. In 2000, several European count
12、ries independently proposed EMC regulations for PLC. Later, the Joint Working Group of CENELEC and ETSI started developing a standard covering the EMC aspects of wire- line telecommunications networks including their in-home extension. The standard scope is focusing on the limits and in-situ measure
13、ments procedures for EMI measurements. Currently the standard is under development. In 2004, the regulatory uncertainty in the USA ended when the FCC approved the Report and Order “Amendment of Part 15 regarding new requirements and measurement guidelines for Access Broadband over Power Line Systems
14、” (ET Docket No. 04-37). The Amendment: a) defines the Access and In-House BPL system; b) contains the emission limits for them; c) describes in detail the measurement procedure for emissions measurements from BPL equipment verification and certification. However, immunity requirements and testing w
15、ere not covered under this document In the USA, narrow band carrier current systems are regulated by the Federal Communication Commission (FCC) under CFR 47 Part 15 Rules for unintentional radiators. Therefore, for such systems the methods, provided by ANSI Standard C63.4 2003 Methods of Measurement
16、s of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz” are fully applicable for emissions measurements. In 2004 the IEEE published its document 643-2004 “IEEE Guide for Power-Line Carrier Applications“ for Low Frequency Power Line Communicati
17、ons covering 50-450 kHz band operations. In 2005 CENELEC published Standard EN 50412-2-1 “Power line communication apparatus and systems used in low-voltage installations in the frequency range 1.6 MHz to 30 MHz. Part 2-1: Residential, commercial and industrial environment. Immunity requirements,” w
18、hich is the first immunity standard for PLC equipment IEEE P1775/1.9.7, March 2009 Copyright 2009 IEEE. All rights reserved. This is an IEEE Standards Draft, subject to change. iii In 2007 the Japanese Ministry of Interior and Communication (MIC) published “Japanese (radio) Regulations for the Broad
19、band PLC (or PLT or BPL)” which is part of Japanese Radio Law and Ordinance regulating Radio Equipment. In 2008, CISPR sent out for circulation the Draft Amendment to CISPR 22, which will describe the limits and method of measurement of broadband telecommunication equipment over power lines. Both th
20、e Japanese and CISPR documents are applicable for in- premises BPL devices. The growing concerns from PLC manufacturers and utility operators about the absence of an internationally recognized EMC measurement and testing methodology for PLC equipment and installations was addressed when in 2004 IEEE
21、 Standards Association established the PLC EMC Working Group P1775 to develop the Standard: “Powerline Communication Equipment - Electromagnetic Compatibility (EMC) Requirements - Testing and Measurement Methods.“ The Working Group is sponsored by the Power Engineering Society, Electromagnetic Compa
22、tibility and Communication Society. The Standard is solely focused on EMC measurement Patents Attention is called to the possibility that implementation of this standard may require use of subject matter covered by patent rights. By publication of this standard, no position is taken with respect to
23、the existence or validity of any patent rights in connection therewith. The IEEE shall not be responsible for identifying patents or patent applications for which a license may be required to implement an IEEE standard or for conducting inquiries into the legal validity or scope of those patents tha
