Abstract

This paper describes a new remote power feeding [RPF] system based on highly safe concepts with many different protection devices. One of them called Tele-Differential/spl copy/ insures to have a safety level comparable to the SELV 48 V while working with voltages close to 400 V. This leading technology overcomes the requirements of the standard EN60950-21 describing the RFT-C/RFT-V circuits by the way, meeting the IEC 479-1 about electric shocks and resulting physiological effects. The communication channel needed for the safety protections, between the remote site and the central office, lead us to implement an enhanced centralised monitoring system based on standard Web application as well as SNMP protocol.
