EV POWER TRANSMISSION LINES Mod. SEL-1/EV
Features
The equipment reproduces two high voltage transmission lines with the possibility of varying the parameters. It enables to learn and test the characteristics and management of high voltage distribution networks, with small scale components. The electric various devices installed, partially connected with one another and with safety terminals, are set at work with extremely simple and quick operations and they enable to modify parameters and circuits at operator’s discretion. The power transmission with insulated lines (IT system) is completed with a three-phase transformer with different possible connections with the primary and secondary circuits.

The fore panel is made of aluminium alloy. Two models of high voltage power transmission lines are represented with the international electric symbols. Proper educational terminals and jumpers with a high degree of protection against accidental contacts allow to use the lines separately or in series/parallel connection. Electric parameters (resistance, inductance and capacitance) may be changed by means of lever selectors according to the different sections and length of line. The presence of voltage is signalled by pilot lamps while protection against overloads relies on quick fuses.
TECHNICAL CHARACTERISTICS:
Framework is made of chemically treated sheet steel, painted with many epoxy coats; the base is provided with rubber feet and it may be positioned on any working top. Lines are protected against overload and short circuit by quick blow fuses.
