PREMO Current Transformers & Sensors Sries Introduction In many applications, to know the current flowing through a given conductor is very useful. As well as the voltage transduction is easy, the comparable process for current is more complex. Because of this need, a lot of technological options have been developed to achieve this goal - measuring electric current. It is important to the designer to understand well ail thse options in order to select the most suitable one. Shunt Resistor Shunt resistors are, maybe at priori, the simplest way to measure current. The principle is based in a...

PREMO Current Transformers & Sensors Sries 鮊 Therefore, it is only necessary an intgration stage on the terminais of the Rogowski coil to get the desired value of current. It's obvious that Rogowski coil can not measure DC levels of current, because voltage is induced by an AC current rather than by a DC current. With an air core, Rogowski coil is able to measure AC current with high level offset, because there are not core saturation problems. 50/60 Hz Current Transformers Another way to measure current is using the magnetic coupling between two coils rolled up in the same magnetic core....

PREMO Current Transformers & Sensors Sries Hall EfFect Based Sensors Hall sensors are based in Hall effect. This efTect consists on the appearance of a voltage when a current flows through a conductive plate and a magnetic fied is applied. Usually this conductive plate is made of a semiconductor material. Voltage generated is perpendicular to the direction of current and the applied magnetic field [1,5],as shown in figure 8: e o S un E \ H 3 Figure 8 This is the Hall configuration. Theoretical relation between voltage generated and applied magnetic field has the form: VH*I-B Where B is the...

Magnetic core, for getting more sensitivity in the transduction, should have a high magnetic permeability and low magnetic losses. Fluxgate...

PRE MO Current Transformers & Sensors Sries With the response signal, an average alonca period oftime is made. This value is always g zro, as long as another induced signal is not added or does not interf驨re in the transducer. If this happens, the mean value is diffrent from zro. c I 驋 This ktnd of sensors measures both AC and DC signais. The following figures (13a, 13b) give us an example of a DC signal measurement. It can be seen that the current directions are opposite respectively. _L 1 . 1 1ח4 1 il J \ V t\ח *_ V i Y t 1 Figure 13. a Figure 13.b Application frequency range ofthis...
