产品详细资料
显示A2 METERING下的总谐波含量 谐波含量 第四天 W1 THDa（第2次至第21次）。运行时THD的显示值应与编程值相同。 检查跳闸、拾取（和报警，如果选择）指示灯是否亮起，并显示以下其中一个：锁定：W1 THD电平或操作：W1 THD电平 降低直流部件，直到元件复位。重置值应比操作值小大约2%。 如果目标功能设置为自复位，则验证相位、拾取和报警指示灯是否复位。跳闸LED应保持锁定状态。7.6.1.2操作时间为了测量该元件的基本操作时间， 预设一个基波和直流分量复合电流信号，使元件工作。 使用图10-1的设置，在触发计时器的同时，突然施加电流。测量的工作时间应与元件的时间延迟设置相对应。小工作电流只有当基本分量的振幅高于阈值设置时，THD元件才会工作。为了验证该阈值， 初将基本分量设置为高于阈值，谐波含量高到足以使元件工作。 现在只减少基本成分。这将具有增加THD水平的效果。当基本成分达到低于设定阈值的值时，元件将重置。
Display the total harmonic content under A2 METERING  HARMONIC CONTENT  THD  W1 THDa (2nd-21st). The displayed value of THD at which operation took place should be the same as the programmed value.  Check that the Trip, Pickup (and Alarm if selected) LEDs are on and one of the following is displayed: LATCHED: W1 THD Level or OPERATED: W1 THD Level  Lower the DC component until the element resets. The reset value should be approximately 2% less than the operate value.  Verify that the Phase, Pickup, and Alarm LEDs reset if the target function is set to Self-resetting. The Trip LED should remain latched. 7.6.1.2 Operating time To measure the basic operating time of this element,  Preset a fundamental and DC component composite current signal to cause the element to operate.  Using the setup of Figure 10-1, apply the current suddenly, at the same time as you trigger the timer. The measured operating time should correspond to the time delay setting for the element.Minimum Operating Current The THD elements will only operate if the amplitude of the fundamental component is above the threshold setting. To verify this threshold,  Initially set the fundamental component above the threshold, with a harmonic content high enough to cause the element to operate.  Now reduce the fundamental component only. This will have the effect of increasing the THD level. When the fundamental component reaches a value below the set threshold, the element will reset.
