产品详细资料
如果启用了来自逻辑输入的阻塞，则可以按照前面对其他元件的测试所述进行测试。7.5.17.5频率衰减率注：需要高质量的可编程函数发生器来验证该元件。由于频率变化率是在窄范围内测量的，因此测试仪器必须准确模拟频率衰减率，而不会有任何明显的抖动。根据GE Multilin的经验，一些具有内置频率斜坡功能的商用专用继电器测试设备不够准确，无法验证745的性能。 禁用除频率衰减功能外的所有保护功能。 验证设置是否符合使用中的要求。在S4元素中输入和修改设置 频率 FREQUENCY DECAY（频率衰减）设定点菜单。以下程序适用于频率衰减率1元件。它们也可以应用于频率衰减率2、3和4元素，在适当的情况下进行必要的改变。电压输入功能（启用电压输入）： 使用连接到端子C11和C12的频率斜坡可编程电压/电流源作为电压信号，连接到端子H1和G1作为电流信号。 将频率设置为60.00 Hz（或50.00 Hz），将电压幅度设置为额定VT二次电压。 将电流幅度设置为额定CT二次（注意：如果此元件的电流感应被禁用，则测试不需要电流信号）。 监测适当的跳闸和辅助继电器。
The blocking from logic input, if enabled, can be tested as described in earlier tests for other elements. 7.5.17.5 Frequency Decay Rate Note A high-quality programmable function generator is required to verify this element. Since the frequency rates of change are measured over a narrow range, the test instrumentation must accurately simulate frequency decay rates without any significant jitter. It is the experience of GE Multilin that some commercial dedicated relay test equipment with built-in frequency ramping functions is not accurate enough to verify the 745 performance.  Disable all protection functions except the Frequency Decay function.  Verify that settings match in-service requirements. The settings are entered and modified in the S4 ELEMENTS  FREQUENCY  FREQUENCY DECAY setpoints menu. The following procedures are for the frequency decay rate 1 element. They can be applied to the frequency decay rate 2, 3, and 4 elements as well, making the necessary changes where appropriate. Voltage input function (voltage input enabled):  Use a frequency-ramping programmable voltage/current source connected to terminals C11 and C12 for the voltage signal and H1 and G1 for the current signal.  Set the frequency to 60.00 Hz (or 50.00 Hz) and the voltage amplitude to the rated VT secondary voltage.  Set the current amplitude to rated CT secondary (Note: if current sensing is disabled for this element, the current signal is not required for the tests).  Monitor the appropriate trip and auxiliary relays.
