The improvement of power quality is mainly through power quality equipment and current signal and other parameters in the current transformer detection system, so as to correctly control the power quality problem in real time and improve the environment of the distribution system. 

For capacitor bank, we usually only use a CT mounted on the power side for sampling. 

For SVG / APF, a set (3) CT is required for the three phases of the system, which is usually recommended to be installed on the load side.

Current transformer is an electrical device used for measurement and protection. Its main function is to convert large current into small current to facilitate measurement, control and protection. In practical applications, the secondary side of the current transformer cannot be open-circuited for the following reasons:

1. Principle of electromagnetic induction: The working principle of current transformer is based on the principle of electromagnetic induction, that is, when there is current passing through the primary side, a corresponding electromotive force will be generated on the secondary side. If the secondary side is open-circuited, the electromotive force cannot form a loop, causing the output signal of the transformer to be unable to be transmitted.

2. Magnetic saturation phenomenon: When the primary side current of the current transformer is too large, the magnetic flux on the secondary side will also increase, which may lead to magnetic saturation. Magnetic saturation will cause the measurement error of the transformer to increase and may even damage the transformer. Therefore, in order to ensure the accuracy of measurement and the safe operation of the transformer, the secondary side cannot be open circuit.

3. Thermal stability problem: The iron core of the current transformer will generate heat during operation. If the secondary side is open, the heat cannot be dissipated, which may cause the temperature of the transformer to rise. Excessive temperature will affect the performance and life of the transformer, and may even cause safety accidents such as fires. Therefore, in order to ensure the safe operation of the transformer, the secondary side cannot be open circuit.

4. Protection function failure: The current transformer has a protective function in the power system. When short circuit, overload and other abnormal conditions occur on the primary side, the secondary side will induce corresponding current, thereby protecting the primary side equipment. If the secondary side is open-circuited, this protection function will fail, which may cause damage to the primary side equipment or a safety accident.

5. Measurement error: The measurement error of the current transformer is related to the load on the secondary side. When the secondary side is open circuit, the measurement error will increase because there is no load. In order to ensure the accuracy of measurement, the secondary side cannot be open circuit.

6. Affects the normal operation of the relay protection device: In the power system, the secondary side of the current transformer is usually connected to the relay protection device to protect the primary side equipment. If the secondary side is open-circuited, the relay protection device may not work properly, causing the protection function to fail.

To sum up, in order to ensure the measurement accuracy, safe operation and effectiveness of the protection function of the current transformer, the secondary side cannot be open circuit. In practical applications, it should be ensured that the secondary side of the current transformer is always closed to avoid open circuit. At the same time, attention should also be paid to the selection, installation and maintenance of current transformers to ensure their normal operation in the power system.

Tube sheet refers to the plate used for supporting and protecting pipelines. Pipelines are usually connected to the tubesheet through mechanical fixation or welding after drilling. In addition to serving as a fixing function, the pipe plate can also withstand the fluid and pressure inside the pipeline, reducing vibration and damage during operation. Carbon steel tube sheet, as a common tube sheet material, has a wide range of applications.

Carbon steel tube sheets are mainly composed of iron and carbon, which contain a high proportion of carbon elements, usually between 0.2% and 2.1%. In addition, it may also contain small amounts of elements such as manganese, silicon, and phosphorus, which can improve the strength and corrosion resistance of carbon steel plates. Here are some main advantages and disadvantages of carbon steel pipe sheets:

Advantages:

1. High cost-effectiveness: Carbon steel, as a common and economical material, is more affordable compared to other high alloy materials, making carbon steel pipe sheets the preferred choice in many applications.

2. High strength: Carbon steel is a type of steel with high strength, and its tensile strength is usually between 400-550MPa. This enables carbon steel plates to have high strength and rigidity under heavy loads and high pressures, enabling carbon steel pipe plates to maintain stability and reliability in high temperature and high pressure environments.

3. Good wear resistance: Carbon steel plates can achieve higher hardness and good wear resistance after heat treatment. Therefore, in some situations where wear resistance is required, carbon steel plate is the preferred material.

4. Easy to process and weld: Due to its low carbon content, carbon steel plates have good plasticity and weldability, and can be processed through various methods such as cold processing and hot processing. This makes the manufacturing and installation process of carbon steel pipe sheets relatively simple and efficient, reducing production costs and time.

5. Good environmental performance: Compared to other materials, carbon steel plates have better environmental performance. It can be recycled and reused to reduce resource waste and also reduce environmental pollution.

Disadvantages:

1. Easy to corrode: Carbon steel plates are prone to rusting, which is one of their biggest drawbacks. Due to the high content of iron in carbon steel plates, rust will occur when they react with oxygen in the air. This not only affects the appearance, but also leads to corrosion and damage to the surface of the board. Compared to stainless steel and other high alloy materials, carbon steel is more prone to corrosion in corrosive environments such as humidity, acidity, and alkalinity, which may lead to damage and shortened lifespan of the tube plate. To address corrosion issues, surface coatings or the use of anti-corrosion coatings can be used to enhance the corrosion resistance of carbon steel pipe sheets.

2. Not suitable for high temperature and strong acid environments: Carbon steel has lower temperature and acid resistance than high alloy materials, so in some applications that require high temperature or acidic media, carbon steel pipe sheets may not be suitable. This drawback can be avoided by welding other alloy materials to alter the performance of the contact surface.

3. Heavy weight: Compared to some lightweight alloy materials, carbon steel pipe sheets are relatively heavy, which may increase installation and maintenance difficulties.

In summary, carbon steel pipe sheets have advantages such as high cost-effectiveness, high strength, and ease of processing. However, their corrosion resistance, temperature resistance, and weight need to be evaluated based on specific application environments, and suitable materials should be selected to meet the requirements.
