Panel for Studying and Testing Distribution Systems
Description & Specification
Panel for Studying and Testing Distribution Systems (Neutral Point Connection)
Categories:
Vocational Education Equipment
Technical Specifications
The actual electric devices assembled in the panel and proper educational terminals with high protection degree against accidental contacts enable to assemble the various configurations, as well as a sight check of the operation: tests can be carried out with traditional instruments. This panel enables teachers to develop an exhaustive class on the state of neutral conductor in distribution systems, so that students can easily learn and test this topic.
PANEL FOR STUDYING AND TESTING DISTRIBUTION SYSTEMS (neutral point connection)
Demonstration panel with electric components
The application fi eld of these devices will cover installations of both civil and business and/or production (handicraft - industrial) sectors. The fore panel of insulating material is the support of the necessary devices for the development of the training program. The apparatuses are indicated on the panel with standard international symbols.
TRAINING PROGRAM:
This panel enables to study electric power distribution systems with reference to the following main topics:
TT, RN and IT systems
Checking the insulation resistance in systems insulated from earth (IT)
Suitability of materials and of equipment
Protections and breaking devices
Moreover, it is possible to carry out the following instrumental measurements and checks:
Protection against direct contacts
Protection against indirect contacts by earthing, electric separation, automatic differential switch
Protection against over-currents, selectivity in protection Devices Earthing system and conductors
Natural, artificial earth plates
Identification of neutral and ground conductors
Measurement of insulation resistance
Measurement of earth resistance
Measurement of fault loop resistance / impedance
Measurement of first earth fault in insulated systems
Continuity tests of protection conductors
Check of the operation of differential switches
Check of the protection with automatic break.
