MR254E Panel For Studying And Testing Distribution Systems (Neutral
Point Connection) Teaching Equipment Electrical Lab Equipment For University
INTRODUCTIONThis 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 componentsThe 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 businessand/or production (handicraft - industrial) sectors.TRAINING PROGRAM:This panel enables to study electric power distribution systems with reference to the following main topics:TT, RN and IT systemsProtection against direct contactsProtection against indirect contacts by earthing, electric separation, automatic differential switchProtection against over-currents, selectivity in protection Devices Earthing system and conductorsNatural, artifi cial earth platesChecking the insulation resistance in systems insulated from earth (IT)Suitability of materials and of equipmentProtections and breaking devicesMoreover, it is possible to carry out the following instrumental measurements and checks:Identifi cation of neutral and ground conductorsMeasurement of insulation resistanceMeasurement of earth resistanceContinuity tests of protection conductorsCheck of the operation of differential switchesCheck of the protection with automatic breakMeasurement of fault loop resistance / impedanceMeasurement of fi rst earth fault in insulated systemsTECHNICAL 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:1 three-phase insulation transformer of230-400 V / 230-400 V 1500 VA1 automatic magneto-thermal switch 4 x 6 A, C curve, with minimum-voltage releasing coil, emergency pushbutton with mechanical holding and warning light indicating panel in operation1 power line of 230 Vac - 1 A for powering auxiliary devices1 three-pole lever switch for inserting two different valuesof earth capacitance in IT line1 simulation of cabin earth with resistance of 0.3 Ω, 1 Ω1 simulation of earth plate with resistances of 2 Ω, 20 Ω, 200 Ω, 2 kΩ2 simulators of electric uses with sinusoidal or one-way earth fault current, fault resistance of 50 kΩ, 15 kΩ, 5 kΩ, 1.5 kΩ, 500 Ω, no-resistance earth fault1 monitor for insulation control in IT systems with regulationof the value of intervention sensitivity and scale for monitoring the instantaneous value of system insulation resistance1 automatic differential magneto-thermal switch 4 x 2 A, C curve, class AC, possibility of using only the magnetothermal switch without the differential section1 four-pole differential circuit breaker of 25 A / 0.3 A, class A, "S" selective1 set of three fuse holders, with breakable neutral conductorand fuses 10.2 x 38 of 1 A and 2 A 1 automatic magnetothermal differential switch 2 x 1 A, curve C, class AC, with possibility of using the only magnetothermal switch without the differential part1 automatic magnetothermal differential switch 2 x 1 A, curve C, class A, with possibility of using the only magnetothermal switch without the differential part1 differential relay coupled to a toroidal transformer with adjustable current Idn and intervention timeDimensions of panel: 800 x 600 mmDimensions of framework: 840 x 450 x 680 mmNet weight: 45 kgREQUIREDUTILITIES (PROVIDED BY THE CUSTOMER)Power supply: 400 Vac 50 Hz three-phase - 1500 VA(Other voltage and frequency on request)OPERATIONAL HANDBOOKWITH EXERCISESACCESSORIES:Three-phase power cord of 5 m with EEC socket and plug20 jumpers with safety plugs of Ø 4 mm for assembling various installation conditionsSet of 20 various leads with safety plugs of Ø 4 mmService
