大型电动机应当使用三相交流电。
The system also includes a switch control circuit to switch the MOSFET switches in synchronization with the three-phase current flow.本系统还包括开关控制电路,用于与三相电流同步切换MOSFET开关。
Because the bank adopts late-model components, high power density, it has not red-hot phenomena. It is pure resistive load and three-phase current balance.本机采用新型功耗组件,功率密度高,无红热现象,为纯阻性负载,三相电流平衡。
Through measuring three-phase current of low voltage at user side and handling by specific algorithm, TA ratio of HV measuring can be accurately judged whether is consistent with data plate.通过测量用户低压侧三相电流相量,通过特定的算法处理,准确判定用户高计TA的实际变比是否与铭牌一致。
KIWA synthetic power saver with his unique structure form eliminates higher harmonic of the electrical network by way of the balance in adjusting three-phase current and voltage.KIWA综合节电装置以其独特结构形式,通过调整三相电流和电压的平衡,消除电网高次谐波。
