• Symmetrical three - phase source
  对称三相电源
• The three - phase circuit that has balanced three - phase sources , balanced ( equal ) three - phase loads and balanced three - phase line - impedances is called a balanced three - phase system
  一个具有对称三相电源，对称三相负载和对称三相线路阻抗的三相电路被称为三相对称电路。
• Three - phase four - wire apf with one - cycle control need not sense the three phase load currents or the three phase voltages , need not calculate the harmonics and reactive current components , as well as the use of any multipliers
  单周控制三相四线制有源电力滤波器不需要检测三相负载电流和三相电源电压，不需要检测谐波和无功电流，也不需要使用任何乘法器。
• Gb1094 . 5 - 85 power transformers part 5 ability to withstand short circuit only applies to power transformers , not to balanced transformers . if short - circuit test on balanced transformers can be performed by means of single phase supply instead of three phase supply , and other special transformers can also be done in this way , so it is very significant to improve test capacity of transformer laboratory in our country
  变压器的短路强度只能通过短路试验来验证，国家标准gb1094 . 5 - 1985 《电力变压器第5部分承受短路的能力》只适用于电力变压器，对平衡变压器等特殊变压器并无具体规定，对于平衡变压器，如果可以用单相电源预先短路法模拟三相电源的短路试验，那么其它特种变压器的短路试验也可以参照进行，这对提高我国变压器试验室的试验能力具有重要意义。
