Advantages of leak testing for cables

Sep 20, 2013 · Unlike previously discussed sensors, leak detection cables (rope-style sensors) are designed to cover expansive and open areas. These cables can also be affixed directly to water supply and return lines, making them ideal for covering large spaces with multiple leak points.

    In the case of gas leak detection in buried pipelines the best location for the sensing cable is above the pipe. At that position there is a maximum probability of collecting the released gas, independently from the leakage location. Figure-6 demonstrates the typical peak received at the point of gas leak detection. .

  • Pros And Cons Of Leak Detection Methods

    A Popular ChoiceClearly Seeing LeaksAnother OptionOne of the earliest electronic leak detectors to be introduced to the industry was the negative corona discharge model. The instrument works by creating a high voltage corona in the sensing tip. When the corona senses refrigerant, the device will sound an alarm. According to Seymour, early models of the negative corona discharge detector had some problems when they were first introduced. Large doses of refrigerant could “poison” the detector and cause it to malfunction. The other type of electronic detector is the heated diode model. The technology heats the refrigerant and breaks the molecules apart, creating positively charged chlorine or fluorine ions. The heated diode detector will sense these ions and set off an alarm. Both the negative corona and heated diode detectors have been improved over the years to prevent them from being too sensitive to large refrigerant leaks. In fact, TIF has made an improvement on leak detection with its ZX-1 Heated Pentode™ refrigerant detector. A...

Many of the methods described in this article can be performed as an acceptance or maintenance test, depending on conditions such as the test voltageapplied or duration of test. The objective of any diagnostic test is to identify problems that may exist with a cable - in a non-destructive way - so that preventative measures can be taken to avoid potential failureof that cable when in service. Diagnostic assessments may apply to cable systems comprising of the cable itself and the associated accessories such as splices and terminations.

    The Advantages of Using Air Leak Testers. Leak testing on production lines—such as for automobiles and gas equipment—has been, up to now, one of the processes causing the most bottleneck. A method often used in general is to seal air in WORK, submerge it in water, then visually check for bubbles. The cons of this method include that it is impossible to ensure that none are overlooked, a drying process becomes necessary, and it cannot be automated.
