Common defects of GIS equipment

According to the defect analysis of GIS equipment, three types of defects, such as common foreign body, assembly and material, can be detected by X-ray digital imaging technology....

Magnetic Particle Inspection - MPI

Magnetic particle inspection is a nondestructive testing method used for defect detection. MPI is a fast and relatively easy to apply and part surface preparation is not as critical as it is for some other NDT methods. ...

Non-destructive testing of GIS equipment by X-ray digital im

GIS equipment is one of the important equipments of the power system, and its operating status plays a vital role in the safe, stable, and reliable operation of the power grid....

Magnetic Particle Crack Detection

During the production of steel (casting), during the processing (rolling, forging, welding) and also during the utilization of steel components (bending and tensile loads) cracks can occur. Most often the crack formation begins at the surface and then...

Principle of X-ray detection

X-rays are electromagnetic radiation waves similar to light, heat and radio waves, which are characterized by short wavelengths....

How Ultrasonic Testing Works

Ultrasonic flaw detection requires a trained operator who can set up a test using the appropriate reference standards, inspect equipment or structures that sometimes feature challenging complex geometries, and properly interpret the results....

Ultrasonic Testing for the Power Generation Industry

Ultrasonic nondestructive testing, also known as ultrasonic NDT or simply UT, is a method of characterizing the thickness or internal structure of a test piece using high-frequency sound waves. ...

X-ray inspection application in non-destructive testing-1

There are many types of rays, and there are three types of X-rays, Y-rays, and neutron rays that are easy to penetrate....

Ultrasonic inspection methods and advantages and disadvantag

There are two different ways in which the ultrasonic waves are detected: reflection and attenuation. In reflection-based modes, the transducer acts as both the ultrasonic emitter and receiver. ...

What is Ultrasonic Testing

Ultrasonic testing is a non-destructive technique that is often performed on metals, alloys, wood, ceramics, concrete and composites....
