During normal operation CB1 is closed and CB2 open. Switchboard S2 is fed by the
transformer. If the main source is lost, the following steps are carried out:
1. The mains/standby changeover switch is operated and CB1 is tripped.
2. Load shedding if necessary of part of the loads on the priority circuit in order to limit the load impact on the generator.
3. Start-up of the generator.
4. CB2 is closed when the frequency and voltage of the generator are within the required

<b>Group trao đổi thảo luận FB: </b>
<b> hỏi 1:</b>
Các em vào website đó tải file IEC 2018 về và tìm các sơ đồ ngun lý nói về cấu hình hệ thống cung cấp điện, sau đó gửi hình chụp các sơ đồ vào đây! rồi chúng ta thảo luận, bạn nào tích cực sẽ được cộng điểm
