Application of Clamp Ammeter in Inspection of High Loss Platform Area
High-loss station areas are often accompanied by problems such as electricity theft, leakage, and meter failures. It not only affects the economic benefits of power supply enterprises, but also destroys the order of electricity consumption. At the same time, the problem of high loss is often not caused by a single problem, but a combination of multiple problems, such as meter failures, electricity theft, or other problems coexisting at the same time. Therefore, it is a meticulous and complicated task to remediate the high-loss platform area and reduce the line loss of the high-loss platform area. Here we mainly discuss the leakage problem in high loss. There are many leakage problems in high loss, how to find them? The actual operation proves that using the clamp ammeter to check the leakage is fast and convenient.
Clamp ammeter: A measuring instrument that can measure the current in a wire by clamping the jaws on the wire. It is easy to use without disconnecting the wire. At present, the clamp ammeter can also realize functions such as measuring voltage and resistance through its own measuring pen.
High-loss platform area: The line loss rate of the public transformer area is less than 0, and it is greater than the theoretical line loss, which belongs to the abnormal loss platform area. Among them, the line loss rate greater than the theoretical line loss belongs to the high loss platform area. According to regional differences, it is usually stipulated that the line loss rate is greater than a certain value and belongs to the high loss platform area [1].
