Panel for Studying and Testing Distribution Systems Neutral Point Connection

Panel for Studying and Testing Distribution Systems Neutral Point Connection

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 of
230-400 V / 230-400 V 1500 VA
1 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 operation
1 power line of 230 Vac - 1 A for powering auxiliary devices
1 three-pole lever switch for inserting two different values
of earth capacitance in IT line
1 simulation of cabin earth with resistance of 0.3 Ω, 1 Ω
1 simulation of earth plate with resistances of 2 Ω, 20 Ω, 200 Ω, 2 kΩ
