Seminar Description

Insulation coordination is fundamental to the design and operation of power systems. In turn overvoltage limitation is an important part of insulation coordination and has evolved from rod gaps through gapped type surge arresters to the metal oxide surge arresters of today. This seminar will discuss the basic principles of insulation coordination and will then cover arrester application and selection in detail.

Topics will include:

• Power system overvoltages: origin and characteristics; travelling wave basics
• Insulation coordination: from overvoltages to rated lightning and switching impulse withstand voltages; role of surge arresters.
• Metal oxide surge arresters: design, characteristics and application; differences compared to gapped type arresters.
• Surge arrester standards: CSA, IEC or IEEE - which is the recommended standard to follow?
• Arrester application in substations: incoming surge steepness and distance effects; arrester selection.
• Arrester application on transmission lines: gapped versus ungapped arresters; future IEC standard; arrester selection.
