It is generally called a PT Cabinet switchgear , where PT stands for potential transformer. The following is an introduction to it:

### Functions
- **Voltage Measurement and Monitoring**: It transforms the high voltage in the power system into a low voltage suitable for use by measuring instruments, protection devices, etc. at a certain ratio. This enables staff to monitor the voltage of the power supply system for agricultural facilities in real - time, ensuring that the voltage is within the normal range and safeguarding the safe and stable operation of agricultural equipment. For example, in a large - scale agricultural irrigation pumping station, monitoring the voltage through a PT cabinet can prevent equipment such as water pump motors from being damaged due to excessive or insufficient voltage.
- **Electric Energy Metering**: It provides an accurate voltage signal for the electric energy metering device, enabling the electricity meter to accurately measure the electricity consumption during agricultural production, which is convenient for cost accounting and energy management. For instance, in an agricultural greenhouse planting base, accurate electric energy metering helps to calculate the planting cost reasonably.
- **Protection and Control**: It supplies a voltage signal to the relay protection device. When abnormal situations such as over - voltage, under - voltage, and ground faults occur in the power system, the PT cabinet, in cooperation with the protection device, acts quickly to cut off the circuit and protect the electrical equipment in agricultural facilities from damage. For example, in a modern farm with a large number of electrical devices, the PT cabinet can protect the equipment safety in case of a fault.
- **Providing Operating Power**: It supplies power to some equipment or devices that require a voltage signal as the operating power, ensuring their normal operation and guaranteeing the reliable operation of the power system in agricultural facilities.

### Characteristics
- **Good Insulation Performance**: High - quality insulating materials are used, which can effectively prevent faults such as electric leakage and short - circuit in agricultural environments, such as humid farmlands and farms, ensuring the safety of equipment and personnel.
- **Appropriate Protection Level**: According to the environmental requirements of different agricultural facilities, it has corresponding protection levels, such as IP30, IP40, etc. This can prevent dust, water droplets, etc. from entering the cabinet and affecting the normal operation of the internal electrical components.
- **High Reliability**: It has stable electrical and mechanical properties. During the long - term and continuous operation of agricultural production, it can reliably achieve functions such as voltage transformation, measurement, and protection, reducing the probability of failure and lowering the maintenance cost.
- **Strong Environmental Adaptability**: It can adapt to various harsh environmental conditions in agricultural facilities, such as high temperature, low temperature, high humidity, and high salinity, ensuring stable operation in agricultural production under different geographical and climatic conditions.

At present, there is no accurate data on the market size of PT cabinets for agricultural facilities. However, with the advancement of agricultural modernization, the demand for PT cabinets will increase. According to the "2023 - 2029 Global and China PT Cabinet Industry Development Research and Trend Prediction Report" from the Market Research Network, PT cabinets are applied in fields such as power systems and industrial automation. With the rapid development of the global power system and industrial automation, the PT cabinet market has been widely used.
