National Grid Simulation Kit
To safely demonstrate the need for high voltage transmission of electricity. This apparatus clearly demonstrates how this is achieved using the interconnected boxes through which pupils can see the components. The high and low voltage sides are clearly indicated, with resistance wires connected to either side for direct comparison of lamp brightness/energy loss. By gripping the insulated cables the energy loss can be felt in the form of heat. There are also voltmeter sockets for measuring the high voltage. Comes complete with two boxes (transmit and receive), insulated resistance wires, two mounted SBC lamps and full instructions. Touchproof, locking high voltage connectors used throughout it is virtually impossible to get an electric shock Clear lid to the casing so pupils can see how it works and trace the circuit Indicators for low/high voltage Voltmeter sockets for measuring the high voltage Supplied with 2 x kits to make up the pylons AC Power supply and Connection wires are not supplied An additional power supply is required to carry out this experiment, capable of supplying 12V at 5A. Also required are 6 x connecting leads.
