老化因子限制老化因子值也是负载、环境温度和变压器额定值的函数。 向绕组1相a施加电流,以表示至少100%的变压器负载。 使用A2计量 生命损失 绝缘老化因子实际值,观察老化因子逐渐增加。 您可能希望增加模拟负载或模拟或编程的环境温度,以使其更快地增加。当老化因子达到S4元素时 绝缘老化 老化因子极限 老化因子限制拾取操作水平,元件应进行操作。 根据FlexLogic验证所有编程的继电器操作™ 设置。 验证所有目标和信息是否符合预期和编程设定。时间延迟可以用手表进行验证,因为延迟通常以分钟为单位设置。4寿命损失限制寿命损失限制元件的典型设置要求更改限制或临时更改变压器的初始寿命损失。建议通过编程设定元件阈值以上的初始寿命损失来验证该功能。该元件立即运行,因为它没有相关的时间延迟。7.5.20分接监测器故障当感测到的电阻比监测器电路的编程值大150%时,分接监测器的故障元件工作。 连接一个电阻来模拟分接开关的电阻,并增加该电阻,直到元件工作为止。 计算元件工作时的电阻为大分接头位置处电阻的150%。 根据编程值验证所有继电器、目标和消息是否正常工作。
Aging Factor Limit The Aging Factor value is also a function of load, ambient temperature, and transformer ratings. Apply a current to Winding 1 Phase A to represent at least a 100% transformer load. Use the A2 METERING LOSS OF LIFE INSULATION AGING FACTOR actual value to observe that the aging factor increases gradually. You may want to increase the simulated load or the simulated or programmed ambient temperature to cause a faster increase. When the aging factor reaches the S4 ELEMENTS INSULATION AGING AGING FACTOR LIMIT AGING FACTOR LIMIT PICKUP operating level, the element should operate. Verify all programmed relay operations as per FlexLogic™ settings. Verify that all the targets and messages are as expected and programmed. The time delay can be verified with a watch as the delay is normally set in minutes.4 Loss of Life Limit Typical settings for the loss-of-life limit element dictate that either the limit be changed or the initial transformer loss-of-life be changed temporarily. Verification of this function is recommended by programming an initial loss-of-life above the element threshold. The element operates instantly as it has no associated time delay. 7.5.20 Tap Monitor Failure The tap monitor failure element operates when the sensed resistance is 150% larger than the programmed values for the monitor circuit. Connect a resistance to simulate the tap changer resistance and increase this resistance until the element operates. Calculate that the resistance at which the element operated is 150% of the resistance that would be present at the maximum tap position. Verify all relay, targets and messages for correct operation per programmed values.
