Introduction to Electrical Bushings (NV)

Electrical bushings are essential components for a wide range of electrical equipment such as power transformers, shunt reactors, circuit breakers, and capacitors. Despite presenting an outward impression of simplicity, bushings have evolved into complex components which perform the critical function of carrying current at high voltage through equipment enclosures and barriers. This course covers the basics of electrical bushings, their major types, construction, design requirements and condition assessment tests. 

You will learn:

• The basic function of an electrical bushing.
• Bushing applications and historical development. 
• Main bushing types and their components. 
• Solid/bulk type bushing design (porcelain, composite resin silicon and cast resin).
• Basic concepts and construction of condenser bushings (capacitance graded bushings). 
• Different condenser bushing technologies (RBP, OIP, RIP and RIS). 
• Contemporary bushing standards and design requirements.
• Different kinds of bushing connections (fixed, draw lead and draw rod).
• What voltage and test taps on condenser bushings are.
• Bushing condition and diagnostic tests (capacitance, Tanδ and partial discharges etc.).
• And a lot more!

Interactive 3D models have been used to show you variuos bushing designs in great detail.

2D images have been used to clarify underlying concepts and theory. 

The course contains a PDF handbook.

Hope to see you on the course!
