Aneesh VN, Associate Product Line Manager for MTL Surge Products at Eaton, explains why surge protection is an essential consideration when designing electrical equipment for industrial applications.
Transient surge events can have costly and devastating consequences for an industrial plant. Any electrical disruption to critical controls and instrumentation could result in major health and safety issues, environmental fines, downtime, public perception issues, revenue loss, and budget depletion caused by emergency repairs and overtime cost. Protecting against surge events is therefore vital for minimising any damage and maximising uptime.
Designing in surge protection
Surge protection should always be deployed as part of a systematic approach, which includes surge protection of AC power to critical equipment and other services including data, telecom and signal lines. All services should be protected using suitable Surge Protection Devices (SPDs) and connected to an equipotential bonding bar with the least wire length (< 0.5m).
