Abstract

The seismic strength of 16 valve damping resistors in the HVDC transmission network of the Electricity Corporation of New Zealand (Electricorp) were upgraded to current design requirements using a base- isolation design. This paper discusses the design, the prototype-testing and outlines briefly the usefulness and limitations of spherically-ended rollers as a base-isolation support.
