There is a sentence called "the slightest difference, the error is thousands of miles", which means a small error, and the result will be a big error.
The terminal block manufacturer Supu feels that this sentence is most appropriate for industrial production. The accuracy in industrial production is very important, otherwise it is easy to produce defective products or even cause industrial accidents.
Today, the general knowledge of the terminal block manufacturer Supu is to share with everyone the error correction method of electrical measuring instruments.
If an error occurs in electrical measuring instruments, it is easy to cause deviations in parameters such as voltage, current, and power, so correcting the error is an urgent task.
Then the main adjustment methods are: correction of scale error (mainly reflected in the value acquisition or recording), correction of electrical transformation ratio error (mainly obtained in the calibration report, when the actual load on the secondary side of the transformer and the calibration When the load is different, the ratio error can be estimated from the change characteristic curve of the transformer at different loads.), The correction of the phase angle error (when the actual load on the secondary side of the transformer is different from the load at the time of verification, the phase angle error β1 can be estimated from the phase angle characteristic curve of the transformer under different loads.
Supp, a manufacturer of terminal blocks, believes that the above are the most effective ways to correct errors. If you are a manufacturer of electrical measuring instruments, you should keep these points in mind. If there are problems in the trial, you can first check from these points.
