Local monitoring system of the permissible temperature for the medium voltage metal-enclosed switchgear and control gear

It is presented a local monitoring system which act in case of permissible temperature exceeding in the contact for the electrical insulation material, power supply cables and for the metallic casing of the metal-enclosed switchgear and control gear, in order to eliminate the failures caused by the permissible temperature exceeding and to increase the energy supply security. Considering the present and future perspectives of IT development, the controls of the medium voltage metal-enclosed switchgear and control gear will be performed locally (from the control room) or remotely, these equipments remain unattended. Therefore, the medium voltage metal-enclosed switchgear and control gear must be monitored regarding the permissible temperature for the various components. In this way we considered useful to assimilate a local monitoring system of the permissible temperature for the metal-enclosed switchgear and control gear.
