Product Description
ZE4124 Panel for Studying and Testing Distribution Systems (neutral point connection)
Panel for Studying and Testing Distribution Systems Neutral Point Connection
INTRODUCTION
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. The actual electric devices assembled in the panel and proper educational terminals with high protection degree against accidental contacts enable to assemble the various confi gurations, as well as a sight check of the operation: tests can be carried out with traditional instruments.
PANEL FOR STUDYING AND TESTING DISTRIBUTION SYSTEMS (neutral point connection)
Demonstration panel with electric components
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. The application fi eld of these devices will cover installations of both civil and business
and/or production (handicraft - industrial) sectors.
Panel for Studying and Testing Distribution Systems Neutral Point Connection
TRAINING PROGRAM:
This panel enables to study electric power distribution systems with reference to the following main topics:
TT, RN and IT systems
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, artifi cial earth plates
Panel for Studying and Testing Distribution Systems Neutral Point Connection
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:
Identifi cation of neutral and ground conductors
Measurement of insulation resistance
Measurement of earth resistance
Continuity tests of protection conductors
Check of the operation of differential switches
Check of the protection with automatic break
Measurement of fault loop resistance / impedance
Measurement of fi rst earth fault in insulated systems
TECHNICAL CHARACTERISTICS:
The framework is of chemically treated sheet steel, painted with several coats of epoxy paint. Its base is provided with rubber feet so that it can be positioned on any working top. The panel also includes all the necessary electrical components for a correct power supply of circuits.
The main components installed on the panel and accessible via safety terminals for plugs of Ø 4 mm, are:
