What is a current transformer? It is a device used to measure alternating current, such as during power generation or transmission, which can convert the alternating current of different devices into the required current of tens to tens of thousands of amperes. It can not only monitor and measure the current size of these lines, but also avoid high voltage hazards.

When it comes to current transformers, I believe everyone is quite familiar with them. They mainly serve to protect the current. Not only can it control measuring instruments, but it can also avoid safety issues. However, many people are not very familiar with current transformers, so what is the function of current transformers? What are the precautions for using current transformers? Let's take a look together with these two questions!

58彩票What are the precautions for using current transformers:

1. Firstly, current transformers are identified based on polarity reduction. If the polarity connection is incorrect, it not only affects the current measurement value but also causes a short circuit in the circuit.

Generally, it can be set at the terminal of the box to avoid insulation breakdown between windings and the formation of high voltage, which may harm personal safety. In addition, the secondary winding must not be open circuited, otherwise there may be overheating or high voltage hazards, which will not only burn out the winding but also endanger personal safety.

On the contrary, transformers with excessive current should not be selected, as this will affect their measurement accuracy. It is best to choose and use it based on specific circumstances. Before installation, it is advisable to learn more about its installation method and usage precautions to avoid accidents.
