The "a few ratios" you are talking about: the ratio of the current transformer in the first or secondary rated current, called the rated interoperability ratio of the current transformer: KN = I1N/I2N Because the rated current of the coil I1N is standardized, the secondary coil rated current I2N is uniform to 5 (1 or 0.5), so the current intestines rated meter -of -the -sensor rated interaction ratio has also been standardized. Kn can also be approximately represented as the number of turning ratio of the first and secondary coils of the transformer, that is, the number of turns of the first and second coils in KN≈kn = N1/N2. The current transformer is actually equivalent to a transformer, which turns large current into small current supply and protection.
What is right upstairs is right. In simple terms, how much is because the current is too large. Leading out for measures and other tasks. It as a line is a 100/5 current transformer, that is, when your instrument display is 5A, then the actual current of this line is 100A. If the display is 3A, the actual current of this line is 60A. If it is 200/5, when your instrument display is 5A, the actual current is 200A, and so on.
The secondary current of the current transformer is generally 5A, but there is also 1A, such as a variable ratio of 100/1, If your instrument is displayed 1A, then the actual current of the line is actually actual. It has arrived at 100A
