Summary This standard applies to low to medium pressure MV and LV distribution grid distribution automation of information transmission distribution line carrier equipment. This standard specifies the medium voltage and low voltage line carrier equipment requirements, including the band, the output level, spurious outputs, as well as the frequency range 3kHz to 30MHz output limits. 30MHz frequency limit is based on the International Special Committee on Radio Interference Conducted disturbances CISPR recommendations on requirements. This standard does not require signal modulation, coding and function and does not contain environmental requirements and test methods. Note: Many countries makes provision for signal transmission. Compliance with this standard does not mean that you can establish a public power supply network and Internet users between electrical equipment, electrical equipment or communications between users. This is not allowed. The purpose of the standard is to limit interference between the signal transmission apparatus, a signal transmission device and the interference between other devices, and signal transmission equipment for sensitive electronic equipment interference. Sometimes interfere with other electrical equipment, power distribution line signal transmission equipment will malfunction. Various equipment installation manual are how to properly use the instructions and warnings on the incorrect use. If it thinks fit, firmly attached to the product contents with the following warning: " can not be used to control the distribution line carrier signaling equipment, which makes the device unable to work, or because of work or negligence endanger personal safety equipment. "
