Abstract
This paper refers to a remote monitoring system of electric contacts with intense currents for eliminating the malfunctions due to imperfect contact and for increasing the security in electrical supply. Most electrical station have been modernized and equipped with modern monitoring equipment and automation. Still at the design stage was envisaged first as automaton for monitoring the temperature on the bars, to can meet operational requirements imposed, on the other hand, to can communicate with other modern automation equipment and monitoring. The comunication of monitoring system with other equipment is accomplished through a MODBUS communication protocol type. Monitoring system can display values of local temperature on the equipement screen, and remote, on the computer screen. Remote transmission of information from local equipement to computer is performed on a serial RS232-485 communication network. The advantage of this system is that local equipment through key can set an allowable limit value of temperature on the bar and to achieve that value of sound or acoustic warning system. The experimental results were obtained in real conditions of operation and showed good functioning of The remote monitoring system of the temperature of detachable contacts from electric cells will be implemented on electric cells manufactured in Romania by SC Automatica SA Bucharest.
