Generally speaking, the mainstream nowadaysHall sensor detects AC currentThe use of can expand the range of communication instruments,Hall sensors detect AC current based on the principle of transformers, and they have a certain current ratio. As electricity users, we need to choose according to the amount of electricity used. If it is a major electricity consumer, such as factories, mines, and enterprises, it is necessary100AThe current we currently use, both single-phase and three-phase meters, cannot accommodate such a large current. Therefore, we need to choose a current transformer to proportionally convert the large current into a small current, and then measure it with a low range instrument. This is equivalent to expanding the range of the AC meter. Current transformer or current transformer detects current through secondary voltage, which is proportional to the current in the secondary coil. It is an industrial transformer that converts large values of voltage or current into much smaller values in the secondary coil. Measurement is carried out through secondary output.

Secondly, we know霍尔传感器检测交流电流It can isolate high currents and improve user safety,We use Hall sensors to detect AC current and convert high current into low current. From the structure of the current transformer, we can see that there is no direct electrical connection between its primary and secondary sides. They are only coupled by a magnetic circuit. When measuring high current, the primary side of the current transformer is directly connected to the measuring circuit, while the secondary side is connected to the AC instrument, which has no direct electrical relationship with the measured circuit. In this way, the measured AC instrument and operator are separated from high-voltage electricity, thus protecting personal safety and instrument safety.

Using Hall sensors to detect AC current can reduce production costs and standardize production instrumentsThe third function of current transformers is to promote standardization in instrument production. We know that the current on the secondary side of current transformers is uniformly made into a standard5ATherefore, as long as the production range is5AJust use an AC ammeter, and then equip different current transformers according to different current levels. This not only reduces production costs but also standardizes instruments, killing two birds with one stone, which is very good.
