“电位”就是某点相对于参考点的电压,通常是指某点对地的电压。“电位分析法”就是利用参考(理论)电位跟实测电位以及人为控制后的各点电位进行对比分析.从而判断出故障点的方法。在修理故障时,正常情况下,人为改变某点电位,受控制的点或相互影响的点(简称关联点)的电位将会跟着变化(非正常部分的关联点不会发生变化),通过测试各关联点的电位,便可分析判断出故障点,达到快速排除故障的目的下面举例说明:
“Potential” is the voltage of a point relative to the reference point, usually refers to the voltage of a point to ground. “Potential analysis method” is the use of reference (theoretical) potential with the measured potential and the controlled potential of each point after comparative analysis to determine the point of failure. When repairing a fault, under normal circumstances, the potential of a certain point is changed artificially, and the potential of the controlled point or the interdependent point (referred to as the associated point) will change accordingly (the relevant point of the abnormal part will not change), and the test passes The potential of the associated points can be analyzed to determine the point of failure, to quickly eliminate the purpose of the following examples:
