Measurement and control system for high-voltage testing equipment

The measurement and control system of high-voltage testing equipment is a complex and critical system used for performance testing of electrical equipment in high-voltage environments. The system mainly includes a high-voltage generation system, a sample, a measurement system, and a high-voltage control system.

High voltage generation systems typically consist of voltage regulators and transformers, which can generate high voltage to apply an electric field to the test object. The test samples include various electrical equipment, such as lightning arresters, short circuiters, insulating oils, transformers, and insulators.

The measurement system is responsible for capturing and analyzing various data generated during the high-voltage testing process. It usually includes equipment such as spectrum analyzers, high-performance oscilloscopes, acquisition cards, computers, current sensors, transformers, and voltage dividers. These devices can accurately measure changes in parameters such as current, voltage, insulation resistance, etc., in order to determine the performance of the test object.

The high-voltage control system is the core of the entire measurement and control system, usually composed of relays, PLCs (programmable logic controllers), and industrial control computers. PLC is responsible for controlling overcurrent protection, voltage measurement, and voltage regulator operation to ensure the safety and stability of the testing process.

In the design and application of the measurement and control system for high-voltage testing equipment, some important factors need to be considered. For example, the stability and reliability of a system are crucial to ensuring the accuracy of test results. In addition, the security of the system is also an issue that cannot be ignored, and various measures must be taken to prevent potential dangerous situations during the testing process.

Overall, the high-voltage testing equipment measurement and control system is a comprehensive system that integrates high-voltage generation, measurement, and control technologies. It can perform accurate and efficient high-voltage testing on electrical equipment, providing important support for equipment research and development, production, and maintenance. With the advancement of technology, the measurement and control system of high-voltage testing equipment is also constantly developing and improving to meet the increasingly complex testing needs.
