Seminar

The purpose of applying surge arresters is to limit overvoltages and enable the cost effective design and operation of power systems. Overvoltage limitation has evolved from rod gaps through gapped type surge arresters to the metal oxide surge arresters of today. A metal oxide surge arrester is essentially a non-linear resistor with a unique voltage-current characteristic and application is very different from the gapped-type arresters of the past. This 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; how surge arresters work 
• Metal oxide surge arresters: design, characteristics and application; differences compared to gapped type arresters.
• Surge arrester standards: CSA, IEC or IEEE - how do these standards compare?
• Arrester application in substations: incoming surge steepness and distance effects; arrester selection.
