This demonstration model helps teachers clearly show how electricity is transmitted efficiently across the National Grid, making complex concepts accessible for secondary and college students. It provides a safe, hands-on way for learners to explore the use of transformers and the importance of high-voltage transmission in reducing power loss.

• Includes two step up/down transformers for converting 12V AC to 115V (nominal)

• 2 metre transmission line with touch-proof, BS EN61010:2010 compliant connectors

• Fibre glass pylons support the transmission line for realistic setup

• Interlock system ensures high voltage is only enabled when safely connected

• Integrated sockets allow safe measurement of high voltage using internal resistors

• Supplied with a detailed manual for guided experiments and discussion

• Power supply not included (e.g. PP00057620)
