RadiSys CE945GM工控卡件

产品详细资料
745计算每个相电流输入中直到21次谐波的各个谐波。利用这些信息，它计算了非正弦负载电流对变压器额定满载电流影响的估计值。这些计算基于ANSI/IEEE标准C57.110-1986，需要的信息通常只能从变压器制造商的测试报告中获得，包括每个绕组的三相电阻和额定负载下的负载损耗。只有在正确输入该信息的情况下，谐波降额系数才会有效。745还计算相电流输入信号的总谐波失真。进行此计算的频带可以更改为比默认的2至21次谐波更具选择性。•谐波降额功能：输入“Enabled”（启用）以启用谐波降额系数计算。•THD小/大谐波数输入计算总谐波失真的频带的小/大谐波数。
The 745 calculates the individual harmonics in each of the phase current inputs up to the 21st harmonic. With this information, it calculates an estimate of the effect of nonsinusoidal load currents on the transformer rated full load current. These calculations are based on ANSI/IEEE Standard C57.110-1986, and require information that is often only available from the transformer manufacturer’s test report, including the three-phase resistance of each winding and the load loss at rated load. The harmonic derating factor will only be valid if this information has been entered correctly. The 745 also calculates the total harmonic distortion of the phase current input signals. The band of frequencies over which this calculation is made can be changed to be more selective than the default 2nd to 21st harmonics. • HARMONIC DERATING FUNCTION: Enter “Enabled” to enable the harmonic derating factor calculations. • THD MINIMUM/MAXIMUM HARMONIC NUMBER Enter the minimum/maximum harmonic number of the frequency band over which total harmonic distortion is calculated.
