Can it be done?

Yes, it is possible to connect a single-phase 20 kW wind generator to a 3-phase 120/208V service.

Equipment required



Step-up transformer

To increase the voltage from 240V to 208V.

Phase converter

To convert the single-phase power from the wind generator to 3-phase power.

Switchgear

Circuit breakers and other electrical components to protect and control the system.

Connection method



Option 1: Voltage Step-Down Step down the voltage from 240V to 208V using a step-down transformer. Connect the output of the transformer to one leg of the 3-phase service. Use a fuse or circuit breaker to protect the leg.

Option 2: Phase Converter Use a phase converter to convert the single-phase power from the wind generator to 3-phase power. Connect the output of the phase converter to the 3-phase service. Use a circuit breaker or other protective device for each phase.

Additional considerations: The size and type of transformer and phase converter will depend on the specific wind generator and service requirements. It is essential to ensure the system is installed and connected by qualified personnel to meet electrical codes and safety standards. The local utility may require additional equipment or approvals for the connection. Flag for review
