产品详细资料
此菜单包含差分谐波抑制百分比设置。如果同一相位的二次谐波超过谐波抑制电平设定值，这是特定相位中的差分元件百分比。谐波抑制参数设置为“2+5th”时，将2次和5次谐波分量的RMS和与电平设置进行比较。在启用谐波平均的情况下，如果谐波的三相平均值超过电平设置，则所有三相都将被抑制•谐波抑制参数：选择“2”，仅将2次谐波电流与谐波抑制电平进行比较。选择“2+5th”以使用2次和5次谐波分量的RMS和。对于大多数变压器，在通电期间，仅二次谐波电流就将超过20%，“二次”值足以抑制差动元件的涌入电流。•谐波平均值：选择“启用”以使用谐波电流的三相平均值来对抗谐波抑制设置。对于大多数应用，不建议启用谐波平均。•谐波抑制水平：输入谐波电流水平（第2级或第2+5级），超过该水平，差动元件百分比将被禁止运行。对于大多数应用程序，此级别应设置为“20%”。
This menu contains the percent differential harmonic inhibit settings. This is the percent differential element in a particular phase if the 2nd harmonic of the same phase exceeds the HARMONIC INHIBIT LEVEL setpoint. With harmonic inhibit parameters set to “2nd + 5th”, the RMS sum of the 2nd and 5th harmonic components is compared against the level setting. With harmonic averaging enabled, all three phases are inhibited if the 3- phase average of the harmonics exceeds the level setting • HARMONIC INHIBIT PARAMETERS: Select “2nd” to compare only the 2nd harmonic current against the HARMONIC INHIBIT LEVEL. Select “2nd + 5th” to use the RMS sum of the 2nd and 5th harmonic components. For most transformers, the 2nd harmonic current alone will exceed 20% during energization and the “2nd” value is sufficient to inhibit the differential element for inrush current. • HARMONIC AVERAGING: Select “Enabled” to use the three-phase average of the harmonic current against the harmonic inhibit setting. For most applications, enabling harmonic averaging is not recommended. • HARMONIC INHIBIT LEVEL: Enter the level of harmonic current (2nd or 2nd+5th) above which the percent differential element will be inhibited from operating. For most applications, this level should be set to “20%”.
