AMAT 1007-0016自动化控制模块

产品详细资料
该元件的小拾取测试与谐波抑制百分比差动元件测试中使用的设置相同（参见第7–4页图7–1：测试设置）。为了测试绕组1的THD元件， 将复合电流信号连接到端子H1和G1。由于直流分量实际上由半波整流信号组成，它包含继电器测量和操作的所有偶次谐波。注意，需要基波分量来防止输入CT饱和。根据继电器FlexLogic监控输出继电器™ 分配 将基本部件设置为额定电流互感器次级（1或5A）。 逐渐增加直流分量以产生均匀的谐波，直到THD电平元件工作。 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。
Minimum Pickup Testing of this element uses with the same setup used in testing the harmonic restraint percent differential elements (see FIGURE 7–1: Test setup on page 7–4). To test the winding 1 THD element,  Connect the composite current signal to terminals H1 and G1. Since the DC component actually consists of a half-wave rectified signal, it contains all even harmonics which the relay measures and operates on. Note that the fundamental component is required to prevent saturation of the input CTs. Monitor the output relays as per the relay FlexLogic™ assignment.  Set the fundamental component to rated CT secondary (1 or 5 A).  Gradually increase the DC component to produce even harmonics until the THD level element operates.  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.
