In the power system, protection devices and systems play an extremely important role, ensuring the safe and reliable working of the power system. The guards are responsible for quickly, reliably and accurately detecting and isolating the fault elements out of the system.

Because the scope of work is spread over the entire Northern provinces, in order to ensure the power supply for the loads, the construction shutdown time is also very short. However, with the support of the operation management unit, the investor, the delivery unit, the ACEE testing unit has completed the assigned work in a “quality – safe – reliable” manner.

The project of renovating/ equipping the 35kV grid ground protection system is implemented on a total of 23PC/179 110kV substations under the Northern Power Corporation EVNNPC.

In this project, ACEE has implemented at stations such as: Thach To 110kV Station (E3.2), Kim Bang 110kV Station (E24.16), Phu Ly 110kV Station (E3.5), Ly Nhan 110kV Station (E24.2), Tuyen Quang 110kV Station (E14.1), Chiem Hoa 110kV Station (E14.2), Son Duong 110kV Station (E14.3), Go Trau 110kV Station (E14.9), Long Binh An 110kV Station (E14.7), Ham Yen 110kV Station (E14.11), Dien Bien 110kV Station (E21.2), Tuan Giao 110kV Station (E21.1), Hoang Mai 110kV Station (E15.17), Chau Khe 2 110kV Station (E27.11), Yen Phong 110kV Station (E27.7), Yen Phong 2 110kV Station (E27.12), Thuan Thanh 110kV Station (E27.9), Gia Luong 110kV Station (E27.2), Binh Dinh 110kV Station (E27.4), Tien Son 110kV Station (E27.1), Thach Linh 110kV Station (E18.1), Song Ma 110kV Station (E17.30), Pho Vang 110kV Station (E4.8), Ba Thuoc 110kV Station (E9.12)….and many more 110kV stations are being deployed by ACEE!
