The L-3P does not need to be wired in and does not need to touch the high voltage exposed live wires. It can directly detect the phase rotation by connecting the three induction high-insulation clamps onto the 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. A tone indicates the normal or reverse phase state of the phase rotation of the three-phase power supply.
