The receiver then uses an adapter to separate the high frequency signal from the current, thus realizing the power transmission of data and signals.<\/p><p>Power line carriers can be carried on high voltage power lines (above 35KV), medium voltage power lines (around 10KV) and low voltage distribution lines (380V or 220V).<\/p><h2 class=\"wp-block-heading\">Development History<\/h2><ul class=\"wp-block-list\"><li>In the early 1900s, power line telephony was one of the earliest attempts to filter electrical signals down the power lines in the same transformer supply line<\/li><li>In 1991, the U.S. Electronic Industries Association, established a home bus standard for power lines<\/li><li>In 1997, Northern Telecom enabled electric utilities to transmit data and voice services at 1 Mbps over power lines<\/li><li>Siemens' Powerline Bus extends applications from the home to cellular telecom access ports and transmits data at 1 Mbps<\/li><li>Thirteen companies, including Cisco, Intel, Hewlett-Packard, Panasonic and Sharp, have formed the HomePlugPowerline Alliance to create a common standard for home powerline network communications technology.<\/li><li>German power industry giant RWE Power has launched a new technology called Power Grid, a new transmission technology that will be able to transmit a variety of Internet data signals through the power lines, thereby greatly advancing the popularity of the Internet<\/li><li>In 2001, Japan's Kyushu Electric Power, Tokyo Electric Power and Mitsubishi Electric, Fujitsu and Panasonic collaborated to develop technology for transmitting and receiving images over power lines.<\/li><li>2001 China Guodian Communication Center conducted PLC application experiments in Beijing residential areas<\/li><li>Due to the special characteristics of the power system, in order to ensure stable and reliable communications, most of the world's electric power companies are mainly self-built to establish a dedicated communication network for the power system<\/li><\/ul><h2 class=\"wp-block-heading\">Working Principle<\/h2><p>When sending and receiving data between two devices, the data is modulated at the transmitter and the modulated signal is superimposed on the AC or DC supply voltage. In the receiver, the data is extracted by separating the supply voltage from the modulating signal with a filter and demodulating the modulating signal.The PLC can be used on AC power lines as well as DC power lines.
