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.

1. Structural differences

The open transformer, as the name suggests, is designed with open characteristics and is usually used for current measurement in low-voltage power grids. Its structure is relatively simple, easy to install, and can adapt to different environments and application requirements. The traditional transformer is a tightly closed transformer, which is usually used for current and voltage measurement in high voltage power grid. It has a more complex structure and a more elaborate manufacturing process.

2. Differences in application areas

The open transformer is mainly used in low voltage power grid for current measurement and monitoring. Because of its simple structure and low cost, it is widely used in some occasions with low precision requirements. Traditional transformer is widely used in high voltage power grid, for the measurement of current and voltage, to provide accurate data for the operation of the power system.

3. Differences in performance characteristics

Due to its simple structure, although the accuracy of the open transformer is relatively low, its response speed is fast and it can adapt to the rapidly changing current environment. Because of its complex structure and high manufacturing precision, the traditional transformer has high measurement accuracy and can provide more accurate power system data.

4. Differences in installation and maintenance

The open transformer is easy to install without special tools and skills. The installation of traditional transformers requires professional technology and tools, and the installation process is relatively complicated. In terms of maintenance, open transformer maintenance is simple, low cost. Because of its complex structure, the traditional transformer is relatively complex to maintain, and the cost is also high.

In general, there are differences between open transformer and traditional transformer in structure, application, performance characteristics and installation and maintenance. The choice of which transformer mainly depends on the specific application scenarios and requirements. In low-voltage power grid, open transformer is widely used because of its low cost and convenient installation. In the high-voltage power grid, the high precision and stability of the traditional transformer make it an indispensable equipment.
