Learn how to upgrade your facility's electrical protection system step by step, from assessment and compliance planning to relay integration, arc flash mitigation, and ongoing maintenance under NFPA 70B and NEC standards. A thorough assessment identifies gaps and informs a prioritized compliance plan aligned with current codes. Continuous testing, monitoring, and iterative updates are essential for ongoing safety. In theory, it is easy to see the advantage of upgrading a protective relay installation from Electro-Mechanical Relays or Solid-State Relays to Digital Relays. But when theory becomes practice, or said another way, when theory meets reality, many unanticipated problems arise. And an upgrade—working. ABB provides various modification and upgrade services that allow product alteration even years after purchase. The modification and upgrade services are available for the vast majority of medium-voltage protection relays and provide an opportunity to modify the product functionality or upgrade the.
