0 parameters, characteristics and error generation of magnetic flux miniature current transformer

0 Flux Micro current transformer current ratio should be in 5a/2.5ma; the operating frequency of the zero flux miniature current transformer is 50Hz; in the 5%-120% measurement range, it is said that the difference is ±0.05% (measured ±0.01%), and the difference linearity is 0.02% (measured 0.01%); phase difference is ± 1 points (measured ±0.2 points); phase difference linearity is 0.5 points (measured 0.2 points); one perforation is also in φ4.

0 features of magnetic flux miniature current transformer: The accuracy of the 0 flux miniature current transformer is relatively high, which changes the defect of the normal phase difference of the conventional micro current transformer 5% measurement point (in detail, refers to the 0.1 level of the current transformer 5% measurement point phase difference allowed to 15 points, some transformers should also be dozens of points.

0 Flux Micro current transformer 5% measurement point phase difference ± 1 points). 0 Flux Micro current transformer equipment itself linearity is very good, in the actual use of the time will not need to have an external power supply; about zero flux miniature current transformer equipment small size 19*17.5*18mm (long width and height) similar to HCT201

, mainly used in high-demand measurement occasions also include a variety of power measuring instruments. 0 The iron core of the flux miniature current transformer has no flux (in theory). The error of this transformer will also be generated by the alternating excitation current provided by the flux, and if it is reduced to zero, the transformer will have no error.

However, when actually using, we should pay attention to the zero flux micro-current transformer is a magnetic flux zero transformer. Theoretically, there will be no error in the use of zero flux miniature current transformer, but because it is impossible to really do 0 flux, and distributed capacitance leakage sense and other reasons, for 0 flux micro-current transformer equipment in the actual use of the time there will be errors, However, the accuracy of the transformer has been increased by at least one order of magnitude, that is to say, this precision has been quite accurate.
