跟踪这些调试步骤过程中对设置所做的修改/更改,并确保所有设置在测试结束时返回到“在用”值。7.5.2谐波抑制差动百分比7.5.2.1说明谐波抑制差动元件百分比设定点位于S4元件中 有差别的 百分比差异。禁用所有其他保护元件,以确保跳闸继电器和辅助继电器仅由受试元件操作。使用万用表,根据FlexLogic的预期设置监测适当的输出触点™. 请参阅继电器设置,了解给定元件运行时应运行的继电器。7.5.2.2小拾取通过向绕组1相A的端子H1和G1施加基频交流电流来测量A相元件的小拾取。当电流从0 A增加时,监测适当的跳闸和辅助触点。将检测到操作的电流值与S4元件进行比较 有差别的 差分百分比 百分比差动拾取设定点。由于工作点通常设置得很低,因此需要对电流信号进行精细控制以获得准确的结果。
Keep track of modifications/changes made to settings during the course of these commissioning steps and ensure that all settings are returned to the ‘in-service’ values at the end of the tests. 7.5.2 Harmonic Restrained Percent Differential 7.5.2.1 Description The harmonic restrained percent differential element setpoints are located in S4 ELEMENTS DIFFERENTIAL PERCENT DIFFERENTIAL. Disable all other protection elements to ensure that trip relay(s) and auxiliary relays are operated by element under test only. With a multimeter, monitor the appropriate output contact(s) per intended settings of the FlexLogic™. Refer to the relay settings to find out which relay(s) should operate when a given element operates. 7.5.2.2 Minimum Pickup The minimum pickup of the phase A element is measured by applying a fundamental frequency AC current to terminals H1 and G1, winding 1 phase A. Monitor the appropriate trip and auxiliary contact(s) as the current is increased from 0 A. Compare the current value at which operation is detected against the S4 ELEMENTS DIFFERENTIAL PERCENT DIFFERENTIAL PERCENT DIFFERENTIAL PICKUP setpoint. Since the operating point is normally set quite low, fine control of the current signal will be required to obtain accurate results.
