Electrical testing in agricultural and livestock environments
PDG-21/EV
This demonstration panel can be used by teachers for their lessons and by students for an easy learning and testing on electric accident-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 test 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, electrical block diagram and lay-out, for an easy reference. Furthermore, when necessary, test points correspond to standardized educational terminals with high protection degree against accidental contacts.
This panel shows an electrical installation that can be found in agricultural and livestock facilities, with reference to the following topics:
- Main switchboard of power distribution
- System breaking
- Protection against direct contacts; protection against indirect contacts
- IP protection degrees
- Protection of electric cables against mechanical damages provoked by animals
- Fire protection
- Fixed power-consuming devices
- Transportable and movable power-consuming devices
- Portable power-consuming devices
- Powering the farm by “TT- TN – IT” distribution system
- Earthing system
- Artificial, natural earth plates
- Equipotential connections
