In an electric power system, the following parameters often need measuring: voltage, current, power factor, power, reactive power and apparent power.
电力系统中常需测量电压、电流、功率因数、有功功率、无功功率和视在功率等参数。
The output power is very stable after the temperature cycling and vibration test. No apparent power decrease has been observed as the device working continuously for 500 h.
该光纤耦合模块连续工作500小时没有发现明显的功率衰减，并且输出功率经温度循环和振动冲击后具有较好的稳定性。
An analytic method of power in nonsinusoidal networks is suggested for the apparent power decomposition into four components, active power, scattered power, reactive power, and forced apparent power.
