The invention discloses a current calculating method for the low power consumption of a fault indicator. The method comprises the following steps: setting a CPU (Central Processing Unit) of an indicator to be in a sleep mode, and setting to delay for 3000ms and activating the CPU; after ...
This paper presents a methodology to calculate the neutral unbalanced current in C-type filters with an ungrounded double Wye topology; this equipment is widely used in the steel sector to mitigate the harmonic content in electrical installations caused by electric furnaces used in metal smelting proc...

Relay counting methods of predicting future failures are particularly unreliable in anticipating failures, and premature servicing of relays can cause more failures than the replacement exercise was designed to reduce. It is much more effective to rely on good diagnostic tools being available, such as...
18 应用运算曲线求取短路电流时 电源计算电抗的通用算法 许跃进 (中国农业大学电子电力工程学院,北京 100083 ) 摘要:运算曲线是求解任意时刻短路电流的有效工具。查运算曲线首先要算出每个电源对短路点 的计算电抗。然而,目前对复杂网络中电源计算电抗的计算模型及方法的研究尚存不足,没有提出 普遍适用的计算公式,更...
Trefoil Cleats that are required to withstand the high forces generated by high short circuit currents will often be spaced at very regular intervals – typically matching the commonly available cable ladder (i.e. 300 mm / 225 mm).The maximum short circuit current values will be quoted with ...

target equilibrium temperature as a target effective power corresponding to the periodic voltage, wherein the program compares a stored allowable power of the capacitor with the target effective power corresponding to the periodic voltage in order to determine whether or not the capacitor is available....
Before power on the system, using insulation test to verify if it is good to improve system performance. Insulation test is to find manufacturing process problems and equipment fault which can not be found before failure happened.In EU,this test is compulsory,even to civil system.Fea...
This might the business world, this would be analogous to knowing indicate that healthcare is not performing as well as what resources are available and what the support center's education in general; however, healthcare is taking over baseline level of performance is. In regards to resources,...
