With the remote controller without son, SNCC avoid its expenses until then to send technicians in the different sub-stations for controlling circuit breakers and disconnecting switches on site. It will save time of execution of the manoeuvre of closing and tripping; and will quickly provide service in transport by rail for freight and travellers.

Introduction The availability of electric power is important for the development of an economy and for a good quality of life. In the coming decade, studies show that the electric consumption will to increase. The most important condition for a reliable supply system is a good functioning transmission system. Scientific literature proposes several researches, problems and solutions using the wireless system in the management of equipment [1,2,3]. Habib and Khaled proposed a novel home energy management system using wireless communication technologies for carbon emission reduction within a smart grid [4]. Wireless powering and communication for implants, based on a Royer oscillator with radio and near-field links was proposed in [5]. Han at al. presented the remote-controllable and energy-saving room architecture based on ZigBee communication [6]. The authors in [7] proposed a wireless power outlet system for smart homes. Design and implementation of control mechanism for standby power reduction was presented in [8]. Sunghoi et al. presented the design and implementation of smart energy management system for reducing power consumption using ZigBee wireless communication module. Authors in [9] presented an optimal energy-balanced cooperative transmission based relay selection and power control in energy harvesting wireless sensor network. In the context of scientific research as the result of this study is inscribed, the goal is to identify and analyse the different scientific issues and technological challenges related to the implementation of a system of remote control of mobile manipulators via a wireless network [10,11]. Electric locomotives SNCC are powered by the catenary line; it is supplied with electric current by the substations in which we find as main elements, the HV/MV transformers, circuit breakers and disconnecting switches. In order to ensure continuity of services in transport by rail for freight and passengers, SNCC had implanted within its facilities electromechanical remote controller for switching and remote tripping of circuit breakers and disconnecting switches located in its 11 substations. Copper conductors connected relays at control office (OC) of the electromechanical relay to remote Likasi located in 11 substations of SNCC; representing each relay circuit breakers and disconnecting switches located in the substations, a switching on operation or trigger an equipment located in any sub-stations was effected by operating a key on the relay that represents the OC. A visual signalling OC allowed to see the actual state of the equipment in the various substations. But, following the theft and repeated destruction by the thunders of copper son that connect the relay located in the substations to those located in OC. Likasi, electromechanical remote is not currently in service. This article aims not only restarting the remote control, but also to ensure that the problem with the repeated theft
