Understanding Voltage-Current Characteristic
ArresterFacts 003 Understanding Arrester Voltage-Current Characteristic Curves

The Voltage-Current (V-I) Characteristic of an arrester is one of its most important parameters. With a quick look at an arrester's (or disk's) characteristic curve one can tell the rating of the arrester, the protective level of the arrester, and indirectly how well it canwill do during a temporary overvoltage. This ArresterFacts explains all of this in detail.

Arrester Disconnector
ArresterFacts 005 - Arrester Disconnector

The arrester disconnector is a very important component of arresters used on grounded AC systems to remove the arrester from the system in case of failure.

What is the value of an Arrester
ArresterFacts 038 What is the value of an Arrester

To determine the real value of an arrester we cannot simply look at its cost, but rather we must look at the effect on a system in its absence.
