A clamp meter is an instrument used to measure the current level of an operating electrical circuit、 which can measure the current without interruption. The clamp type meter is actually a current transformer、 and the stuck wire is equivalent to the primary coil of the transformer. When there is current in the wire、 magnetic flux is generated in the iron core of the meter、 and then a current is induced in the secondary coil of the meter. This current is equal to the current in the primary coil multiplied by the number of turns in the primary coil (i.e.、 a wire、 so it is one turn) divided by the number of turns in the secondary coil、 and based on this relationship、 You can convert the current in the wire
A clamp type ammeter is actually an electromagnetic inductor. A wire that is energized generates a magnetic field、 and the magnitude of the current produces a different magnetic field intensity. The current values converted on the clamp type ammeter are different due to differences in three-phase voltage、 so the current holes on each phase are different. Therefore、 only single-phase current can be measured、 and the average current can be calculated after that. Finally、 whether it is a three-phase 380V voltage or a two-phase 220V voltage、 the method used is the same
