Seminar Description

The purpose of applying surge arresters is to limit overvoltages and enable the cost effective design and operation of power systems. Metal oxide surge arresters are thermally limited non-linear resistor devices with a unique voltage-current characteristic. Application involves the selection of rated voltage, protective levels, energy absorption capability, and more. In the past so-called Line Discharge Classes were used to define thermal energy absorption capability relating it to the switching surge protective level and rated voltage. This approach has been removed in the latest version of the arrester standards and thermal energy absorption capability is now related to rated voltage only. In addition, for the first time, the standards treat single shot energy absorption capability.


The seminar will discuss power system overvoltages and then cover arrester application, selection and location in detail. Topics will include: 
  • Power system overvoltages: origin and characteristics; travelling wave basics. 
  • Metal oxide surge arresters: design, characteristics, and application.
  • Arrester application in substations: incoming surge steepness and distance effects; arrester selection. 
Classwork: Please bring a  a calculator, a ruler, and squared paper to the seminar.

Target Audience

System planning engineers, surge arrester application and specification engineers, and engineers involved in type and quality assurance testing.
