Connections:

• The 132kV bus is connected to the primary side of the transformer.
• The secondary side of the transformer is connected to the 11kV bus.
• The tertiary side of the transformer is connected to the 0.4kV bus.
• The 0.4kV bus is connected to the load (230V/50Hz).
• The LTB circuit breaker is connected to the 11kV bus and is used to switch the circuit on and off.

Important Notes:

• This diagram is a simplified representation and may not reflect the actual wiring configuration in your specific installation.
• Always follow the manufacturer's instructions and local electrical codes when installing and maintaining electrical equipment.
• Ensure that all connections are made according to the manufacturer's specifications and that the equipment is properly grounded and insulated.
