hanning windowed interpolation harmonic analysis algorithm and high-order sine fitting algorithm are the two effective algorithms for dielectric loss angle measurement.
the measurement of dielectric loss angle is one of the main methods in the preventive tests for the insulation of electrical equipment.
电气设备绝缘预防性试验中的介质损失角正切的测量,则是一种使用较多而且对判断绝缘较为有效的方法。
the results of simulation and tests indicate that using the proposed algorithm the dielectric loss angle can be measured more accurately while less calculation amount is increased.
仿真和试验结果表明该算法在增加较少运算量的同时提高了介质损耗角的测量精度。
through demarcating sensor and corresponding regress manage, can get relation between dielectric loss angle and grain moisture content. the relation was stored to memory of single-chip computer.
