Protective devices and their selectivity

Achieving selectivity (discrimination) between various tiers of protection where critical loads are supplied is often required. However, the fundamental principles are sometimes misunderstood by the designer, causing incorrect use of software or misinterpretation of device characteristics. This lecture will examine differing low voltage protective device technologies and review the basic process of achieving selectivity between various device technologies at this voltage level. Building on past presentations, the speaker will also examine related real-world problems.

This event is a free of charge in person event (open to IET members and non-members). Please pre-register to attend.

Speaker: Martin Woodcock is a Technical Director within Jacobs. Over the past 20 years Martin has worked in electrical design on a diverse range of projects, covering both low and high voltage systems. He has a passion for system protection, safety and reliability. Martin has worked in electrical design positions at most levels and has been an in-house technical authority for safety critical power design, requiring an in-depth understanding of protection coordination.
