产品详细资料
注入I1电流，使得接地差分拾取值除以I1电流小于斜率设置。设置I2=0 A。由于电流显示为接地差动，因此元件将工作。 斜率由Iground微分和Imax的值计算得出，如下所示：（EQ 7.11），其中I max表示被测绕组的大相电流。随着I2的增加，当坡度百分比下降到坡度设置以下时，图元将重置。 缓慢增加I2，直到元件再次工作。 计算该点的坡度。 将斜率设置降低至0%，然后继续增加I2电流，直到元件复位。 缓慢增加I2，直到元件再次工作。重置水平应为操作水平的97%。当元件复位时，如果W1 RESTD GND FAULT TARGET（W1复位接地故障目标）被选择为“Latched”（锁定），则跳闸和信息LED应保持点亮。否则，只有跳闸LED应保持亮起。7.5.14.6绕组2或3元件由于第二个限制性接地故障元件可以设置与个元件绕组完全不同的参数，因此有必要对每个绕组重复本节所述的全套测试。
Inject the I1 current such that the ground differential pickup value divided by the I1 current is less than the slope setting. Set I2 = 0 A. The element will operate since the current appears as ground differential.  The slope is calculated from the values of Iground differential and Imax as shown below: (EQ 7.11) where I max represents the maximum phase current for the winding being measured. As I 2 is increased, the element will reset when the percentage of slope drops below the slope setting.  Slowly increase I2 until the element operates again.  Calculate the slope at this point.  Decrease the slope setting to 0% then continue to increase the I2 current until the element resets.  Slowly increase I2 until the element operates again. The reset level should be 97% of operate level. When the element resets, the Trip and Message LEDs should remain on if the W1 RESTD GND FAULT TARGET was selected as “Latched”. Otherwise only the Trip LED should remain on. 7.5.14.6 Winding 2 or 3 Elements Since the second restricted ground fault element can be set with completely different parameters than the first element winding, it is necessary to repeat the full set of tests described in this section for each winding.
