Transformers work by converting electrical energy from one voltage level to another through electromagnetic induction.

• Transformers consist of two coils of wire, known as the primary and secondary coils, wrapped around a core made of iron or steel.

• When an alternating current flows through the primary coil, it creates a changing magnetic field which induces a voltage in the secondary coil.

• The ratio of the number of turns in the primary and secondary coils determines the voltage...read more

Yaw is typically done during commissioning or maintenance of wind turbines to ensure proper alignment with the wind direction.

• Yaw is typically done during commissioning of a wind turbine to ensure it is properly aligned with the wind direction

• Yaw may also be done during maintenance to check and adjust the alignment if needed

• During yaw, the nacelle of the wind turbine is rotated to face the wind direction for optimal energy production
