National grid simulator (Each)

Item #: XLE255010

National grid simulator (Each)

A new safe form of the classic experiment for demonstrating the need for high
voltage transmission. Comes complete with two transformers (transmit and
receive), insulated resistance wires, two mounted SBC lamps and full
instructions. **Features:
• **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
• The resistance wires can be connected to either the high or low voltage
system for direct comparison of lamp brightness/energy losses. By gripping the
insulated cables, students can feel when and where the energy is being lost,
mainly as heat Voltmeter sockets for measuring the high voltage
**Please Note:** If 12V is used as the input voltage, voltage should not be
measured at the red socket unless a high impedance meter with only 2 sockets,
equipped with GS38 compliant probes is used. Teachers wishing to show how the
voltage is stepped up and who do not have access to such equipment should
reduce the supply voltage to 3V and use 3.5V MES bulbs.
