Substation Arrester Condition Assessment
The "When to Replace?" Question "When is the right time to remove old arresters from the system?" is a question that is asked every day by asset managers around the world. The answer is not an easy one because the condition of the arresters are generally not known. The following questions remain unanswered: Are they still protecting? What is the risk of failure? How much longer can they be used? If they fail, are they a risk to nearby equipment? How many do I have on the system? How much will it cost to replace them? How much effort is involved in removal? What are the benefits of leaving them installed? What are the benefits of removal? ArresterWorks can assist asset managers in answering the above questions by employing a Substation Arrester Condition Assessment. This assessment consists of the following steps.
