What are the advantages of closed style miniature current transformers?

Generally, the closed style miniature current transformer is similar to the Hall type current clamp, that is, there are two types of open-loop and closed-loop Hall. For the closed style miniature current transformer, its output is current or voltage signal. But because it is closed, it will be much more accurate than a current clamp of the same type.

Furthermore, for silent type micro current transformer, because it is the use of the flux-gate technology of a current sensor, so when it comes to its accuracy, under normal circumstances, will directly is better than 0.05%, we will find that it can be directly even 12 PPM, but in terms of this type of sensor, it not only is very expensive, And it's actually vulnerable in some ways.

In other words, when the closed style miniature current transformer is in use, the sensor will be damaged if there is no direct power supply to the sensor and the measured current passes through it.

Also it is important to note that for silent type micro current transformer or transformer, it connects with the rf power analyzer, with respect to its PA5000 power analyzer for current measurement, it can directly input and sensor input to our port in both groups, when we use the sensor or is silent type micro current transformer output current signal, It can also be plugged into a direct current input port of the PA5000; When the current sensor or closed style miniature current transformer is used, its output is voltage signal, we can directly connect it to an external sensor port of PA5000. In this way, we can directly set a "sensor ratio" of PA according to the used sensor or miniature current.

We manufacture various precision current transformers and voltage transformers, which are widely used in electric power, energy, telecommunication, railway, industrial control and other fields.
