标题[问题] 三相电路计算
时间Thu Jul 8 11:52:46 2010
480
A -------- Vrms line feeds two balanced three-phase loads.
─
∕ 3
If two loads are rated:
─
Load1: 5∕5 kVA at 0.8pf, lagging
─
Load2: 10∕5 kVA at 0.6pf, leading
480
Determine the rms magnitude of the line current from the ------ Vrms source.
─
∕ 3
请问这题目最後一行要求甚麽...
这是三相不平衡 的 负载不平衡电路吗?
题目也没写是Y接还是三角接 这种题目我该从何算起?
