| Abstract: | Qiaogong Hydropower Station had ever seen the third harmonic 3W generator stator earthing protection fails to work under no-load condition. In view of this problem, additional position contacts of generator terminal switchgear are designed in the protection circuit, so as to acquire more correct and reliable protection. |
