The principle of current transformer is based on the principle of electromagnetic induction. The current transformer is composed of a closed core and a winding.  Its primary winding turns are very few, and it is connected in the circuit of the current to be measured,...

In the power generation, transformation, transmission, distribution and use of electricity in the line the size of the current varies, from a few to tens of thousands of amps.  In order to facilitate measurement, protection and control needs to be converted to a more...

Current transformer and transformer similar is also based on the principle of electromagnetic induction, transformer is to change the voltage and current transformer is to change the current.  Current transformer connected to the current measured winding (turns number...

2.1 rated capacity: the apparent power consumed when the rated secondary current passes through the rated secondary load. The rated capacity can be used in apparent power V. A means, can also be expressed with the secondary rated load impedance.  2.2 primary rated...

According to different uses, current transformers can be divided into two categories:  measuring current transformers (or measuring windings of current transformers) : In the normal working current range, to measure, measurement and other devices to provide current...

When measuring the high current of alternating current, it is necessary to convert the secondary instrument to a more uniform current (the secondary rating of the current transformer is 5A or 1A in China) , in addition, the voltage on the line are very high, such as...
