This session brings together a range of perspectives on electrical protection within industrial environments: one presentation analyses damage frequency and the operational limitations of SPDs and LPS in PV plants; another addresses case studies on electromagnetic interference control in data centres; and one more presentation examines the use of flexible metallic conduit systems in industrial installations.    

Grounding is an essential component of any electrical installation, whether operating at high, medium or low voltage, and is particularly important for protection against lightning strikes and overvoltages. As such, it is addressed in all relevant technical installation standards, while Dedicated standards also exist covering its design, construction and measurement. To ensure that electrical professionals fully understand what grounding is, ist purpose, and how it should be designed, installed and maintained, this workshop will be presented by two specialists who work directly in this field and have contributed to the development of the relevant technical standards. They will address the key aspects of grounding, some of its most controversial topics and the issues that most frequently give rise to practical questions.   Topics: 1) What is, and what is not, a grounding system; 2) Which standards should be applied to particular grounding systems; 3) Resistance or resistivity: when, how and what to measure; 4) Common grounding or separate grounding systems; 5) The difference between grounding and equipotential bonding.
