If there is a leak in the pipeline, the voltage of receiving transducer changes immediately. The leak position can be located with curve or formula.
若管道中出现泄漏,接收换能器的电压立即发生变化,可以根据这种变化发现泄漏,进而按拟合曲线或方程序计算出管道泄漏的位置。
The faults include open circuit, short circuit and poor contact. It also can be used to telemetry the position of the fault, including the leak grounding, wire breaking and poor contacting.
同时也可以对电力电缆的高阻闪络、高低阻性的泄漏性接地和电力电缆的断线、接触不良等故障位置进行遥测。
Where possible, the closed position should be determined by leak test using water or air, under low pressure.
如果可能的话,可以用水或空气,在低压状态下,对关闭状态进行测试,看看有没有泄漏。
