Application of High-voltage Power Supply in NDT Inspection

Introduction

Non-destructive testing (NDT) is a technique for detecting and evaluating defects in materials, components, or equipment without causing any damage. High-voltage power supply (HVPS) has become an important and effective auxiliary tool in numerous NDT methods. This article discusses the application of high-voltage power supply in NDT inspection and its advantages.

1. Principle of High-voltage Power Supply in NDT Inspection

The high-voltage power supply generates high voltage and provides it to the equipment to be tested, making the defects in the equipment visible under the action of electric field. In NDT inspection, the high-voltage power supply is usually used in conjunction with sensors, probes, and other auxiliary equipment to detect defects in materials.

2. Application of High-voltage Power Supply in NDT Inspection

The high-voltage power supply has a wide range of applications in NDT inspection, including the following:

2.1 Non-destructive testing of metals

The high-voltage power supply is mainly used for non-destructive testing of metals. By applying high voltage to the surface of metal materials, internal defects such as cracks, bubbles, and the like can be excited, enabling fast, efficient, and non-destructive testing of metal materials.

2.2 Non-destructive testing of composites

The high-voltage power supply is also widely used in non-destructive testing of composites. By applying high voltage to the surface of composite materials, internal defects such as delamination, cracks, and the like can be excited, enabling fast, efficient, and non-destructive testing of composite materials.

2.3 Non-destructive testing of concrete

The high-voltage power supply is also widely used in non-destructive testing of concrete. By applying high voltage to the surface of concrete materials, internal defects such as cracks, defects, and the like can be excited, enabling fast, efficient, and non-destructive testing of concrete materials.

3. Advantages of High-voltage Power Supply in NDT Inspection

The advantages of high-voltage power supply in NDT inspection are mainly reflected in the following aspects:

3.1 High sensitivity

High-voltage power supply can generate high voltage, resulting in very high output voltage for the probe, which improves the sensitivity of the detection and makes it possible to detect smaller defects.

3.2 High resolution

High-voltage power supply can generate high voltage, resulting in very high output voltage for the probe, which improves the resolution of the detection and makes it possible to detect finer defects.

3.3 High efficiency

High-voltage power supply can generate high voltage, resulting in very high output voltage for the probe, which improves the efficiency of the detection and makes it possible to perform non-destructive testing quickly and efficiently.

4. Conclusion

The application of high-voltage power supply in NDT inspection has been widely recognized, its advantages, such as high sensitivity, high resolution, and high efficiency, making it an indispensable auxiliary tool for NDT inspection. With the continuous development of technology, the application of high-voltage power supply in NDT inspection will become more widespread, making a significant contribution to the development of NDT inspection technology.
