ABB SNAT603CNT
是一種勵磁系統，被定義為通過磁場繞組中的電流產生磁通量的系統。這種系統主要應用在同步電機轉子繞組，為其提供必要的勵磁電流。
ABB SNAT603CNT勵磁系統的可靠性、控制簡單性、易維護性、穩定性和快速瞬態響應都是其主要優點。所需的勵磁量取決于負載電流、負載功率因數以及機器速度，當負載電流大時系統需要的勵磁更多，轉速越低，系統的功率因數就會變得滯后。
ABB SNAT603CNT勵磁系統是一個單獨的單元，每個交流發電機都有一個發電機形式的勵磁機。集中勵磁系統有兩個或多個為母線供電的勵磁機，這種系統設計較為便宜，但是系統中的故障可能會對發電廠中的交流發電機產生不利影響。
It is an excitation system defined as a system that generates magnetic flux through the current in the magnetic field winding. This system is mainly used in synchronous motor rotor windings to provide necessary excitation current.
The reliability, simplicity of control, ease of maintenance, stability, and fast transient response of the ABB SNAT603CNT excitation system are its main advantages. The required excitation amount depends on the load current, load power factor, and machine speed. When the load current is high, the system requires more excitation, and the lower the speed, the power factor of the system will become lagging.
The ABB SNAT603CNT excitation system is a separate unit, with each AC generator having an exciter in the form of a generator. The centralized excitation system has two or more exciters that supply power to the busbar. This system design is relatively inexpensive, but faults in the system may have adverse effects on the AC generator in the power plant.
