Demonstration Panel
Specification
This panel can be used by teachers for their lessons and by students for an easy learning and testing on electrical prevention systems supplying them with the means for verifying the rule of art and the relevant technical standards. Actual electrical devices installed, already connected with each other, enable to check the operation, besides carrying out the measurements of all the electric parameters with conventional instruments. The panel is made of insulating material and it represents the support of the necessary devices for carrying out the testing programme. The apparatuses are represented on the panel with their standardized international symbols and electrical block diagram,
This panel can be used to defi ne the electrical installations of a building (power distribution via TT system) with reference to the following topics:
Electrical installation of the building complying with guide
Graphic symbols for installation plans
Branch exchange for a fl at
Meter room and riser
Earthing system for the block of fl ats
Furthermore, this panel is designed to deal with topics,
visual checks, tests concerning:
Protection systems against direct and indirect contacts
Choice of conductors, current-carrying capacity and voltage drop
Testing the paths of conductors and their suitability and duct diameter and removableness of conductors
Suitability of materials and of equipment
Protection and breaking devices
Identifi cation of neutral and earth conductors
Suitability of the connections of conductors
Continuity of protection and equipotential conductors
Isolation resistance
