The function of split-core current transformer

The split-core current transformer is a type of power measuring instrument used to measure current in high voltage power systems. Its function is to convert the high current in the power system into a smaller current to ensure the safety, reliability, and accuracy of the meter. The main functions of the split-core current transformer include:

1. Achieving current measurement: The split-core current transformer can measure the current in high voltage power systems and provide feedback to metering instruments or protective devices for measurement, monitoring, or protection operations.

2. Improving circuit safety: By converting the high current in the power system into a smaller current, the split-core current transformer enhances circuit safety. This helps prevent damage or danger to meters or protective devices.

3. Reducing equipment costs: Since the split-core current transformer can convert high currents in power systems into smaller currents, it can reduce the cost of meters or protective devices. This is because high currents or voltages require special materials and structures, which are more expensive.

The Application of Split Core Current Transformer

The split-core current transformer has a wide range of applications in power systems, mainly including the following aspects:

1. Power Metering

Accurate measurement of electrical energy is crucial in power systems. Split-core current transformers can convert high voltage currents in power systems into lower currents, ensuring the accuracy and safety of metering. Split-core current transformers are available with accuracy of 0.2, 0.5S, 0.5, and 1.

2. Protection Operations

Protection operations such as over-current protection and ground protection are often necessary in power systems. Split-core current transformers can provide accurate current information for these protection operations. 

Protection grades include 5P20, 5P10, 10P10, 10P15, and 10P20.

3. Monitoring and Control

Split-core current transformers can also be used for monitoring and controlling currents in power systems to improve circuit stability and reliability. This includes transformer energy consumption monitoring systems and switch-gear energy consumption monitoring systems.

In summary, split-core current transformers play a crucial role as important power measuring instruments in power systems. They provide accurate current information, ensure the safety and reliability of circuits and metering accuracy, while reducing equipment costs and enhancing the stability and reliability of power systems.
