L-3P phase sequence meter
L-3P phase sequence meter is a major breakthrough in traditional phase sequence detection methods. The traditional phase sequence detection must be to open the three-phase wire terminal, the phase sequence meter of the three exposed clips or test pins are connected to the exposed three fire lines. It uses clamp-type non-contact inductive measurement. It does not need to open the wire, and does not need to touch the high voltage exposed live wire. It can directly detect the phase sequence by sandwiching the three super induction high-insulation clamps to clamp the three-phase live wire insulation sheath. It is safe and reliable, and is widely used in electric power, communication, meteorology, railway, oil field, construction, measurement, scientific research and teaching units, industrial and mining enterprises and other fields. At the same time, the acoustooptic indicates the normal or reverse phase state of the phase sequence of the three-phase power supply.
