Do you know what grade 05, grade 05s and grade 02 mean in current transformer?

Current transformer is an important electrical measurement equipment, which is widely used in current measurement, monitoring and protection of power system. On the current transformer in the "05 level", "05s level" and "02 level", these are about the description of the transformer accuracy level. The accuracy class determines the accuracy of the current transformer measurement.

Minor problems that may occur in current transformer applications

The current transformer is a very important equipment in the power system, which is used to convert high current to low current for easy measurement and protection of equipment. However, in practical applications, current transformers may have some minor problems, which may affect the performance and safety of the system.

How to choose ac current transformer?

AC current transformer is one of the important equipment in power system, which is used to measure current and convert it for monitoring, measurement and protection. Choosing a suitable AC current transformer requires consideration of several factors. Here are some suggestions on how to choose an AC current transformer:

The Use Principle of Open-close Current Transformer

The open-close current transformer is an important power measurement equipment, which is widely used in various fields of power system. In order to ensure its normal operation and measurement accuracy, the following principles should be followed when using open-close current transformers:

The difference between current transformer and voltage transformer

Current transformer and voltage transformer are very important equipment in power system. Their main function is to convert high voltage and high current into voltage and current values suitable for instrument measurement or protection. Although they are both transformers, there are obvious differences between them.

The difference between open transformer and traditional transformer

Open transformer and traditional transformer are two important equipments in power system. They play an important role in measurement and protection of power system. Although they have similar functions, there are some significant differences in structure, application and use characteristics. Below we will detail the difference between these two transformers.
