Getting Started with Surge Arrester Specifications

With the recent and upcoming revisions of IEEE C62.11 and IEC 60099-4 surge arrester standards, writing a technical specification for arresters can be challenging for both new and experienced engineers. Most arrester manufacturers have a dedicated team of engineers who are familiar with the evolving standards and can support the revision and/or creation of arrester specifications.

Surge arrester specifications can be written for dedicated applications or for general purposes to ensure only high quality and proven products are considered. As a best practice Hubbell Power Systems, Inc. recommends considering input from several manufactures which will allow all bidders to offer their best available products.

Consider the following points to get started:

• Define the application such as distribution, station or transmission
• Set general requirements such as minimum experience for manufacturers, and qualifying information that should be supplied with each bid
• Define the arrester standard being used. IEEE and IEC requirements should not be combined
• Outline product characteristics and requirements for critical arrester features and components
• Set expectations for submitting routine and quality assurance testing information
• Request a Type Test Report from arrester manufacturers
