Cascaded surge protection devices(SPD)located at the service en trance of a building and close to a sensitive equipment are required to ensure t hat each device shares surge in optimal manner to achieve reliable protection fo r equipment against it originated from the utility supply.Coordination experimen ts of two different kinds of SPD are done
the energy absorbed by varistor is co mputed and whether the coordination is effective is analyzed.
