RADISYS EPC-2数字量输入卡件

产品详细资料
测试原理745采用数字硬件和软件算法，使用广泛的内部监控实现。因此，预计如果输入电路、CT、VT、电源、辅助信号等正常工作，继电器内的所有保护和监测功能也将根据应用设置正确运行。因此，只需对输入电路进行校准，并对保护和监测功能进行粗略验证，以确保功能齐全的继电器投入使用。尽管本节中介绍了测试，以验证745中包含的所有功能的正确操作，但只有那些投入使用的功能才需要测试。跳过所有涵盖继电器运行时未包含或未启用功能的部分，下一段的规定除外。一些功能，如目标的本地/远程重置、显示消息和指示，对所有保护功能都是通用的，因此只测试一次。谐波抑制百分比差速器包含了这些功能的测试，该功能几乎总是启用的。如果由于某些原因，该元件在继电器运行时未启用，则在测试另一个保护元件时需要测试本地/远程复位。
Testing Philosophy The 745 is realized with digital hardware and software algorithms, using extensive internal monitoring. Consequently, it is expected that, if the input circuits, CTs, VTs, power supply, auxiliary signals, etc., are functioning correctly, all the protection and monitoring features inside the relay will also perform correctly, as per applied settings. It is therefore only necessary to perform a calibration of the input circuits and cursory verification of the protection and monitoring features to ensure that a fully-functional relay is placed into service. Though tests are presented in this section to verify the correct operation of all features contained in the 745, only those features which are placed into service need be tested. Skip all sections which cover features not included or not enabled when the relay is in service, except for the provision of the next paragraph. Some features such as the Local/Remote Reset of targets, display messages and indications are common to all the protection features and hence are tested only once. Testing of these features has been included with the Harmonic Restraint Percent Differential, which will almost always be enabled. If, for some reasons, this element is not enabled when the relay is in service, you will need to test the Local/Remote Reset when testing another protection element.
