Protective devices and their selectivity

A Midlands Power Group (MPG) Event

03 Jul 2024 /  
6:00pm - 8:00pm


Achieving selectivity (aka discrimination) between the various tiers of protection where critical loads are supplied is a well-known requirement of BS 7671.

However, the fundamental principles are sometimes misunderstood. This informative lecture will examine differing protective device technologies and review the process of achieving selectivity.

Building on past presentations of a similar nature, the speaker will also examine problems encountered during the system design phase and how these were overcome.


Martin Woodcock is a Technical Director within Jacobs's Transportation division. Martin has worked on a diverse range of electrical design projects within the rail industry over the last 20 years. He has a passion for system protection, safety, and reliability through design.
