Lightning is a natural phenomenon which cannot be prevented. By its very nature, lightning presents a major threat to structures, systems and people. Effective, correctly installed lightning protection is vital in order to save lives, reduce the risk of damage caused and avoid costly disruption to business critical systems.

Presented by experts from ERA Technology Ltd and Cobham Technical Services - Lightning Testing and Consultancy this intensive one day course examines the phenomena and physics of lightning, and provides an understanding of lightning standards. The potential for damage and concepts by which structures and electrical systems can be protected from direct lightning strikes, will also be studied. The course also examines the application of earthing and bonding techniques, together with the design and test techniques which are necessary for designing effective lightning protection. Case studies are used to illustrate the application of various protection systems for a variety of buildings and systems.

Poor power quality is any variation in an electrical power supply which results in mal-operation or premature failure of equipment. The variations can be caused, for example, by voltage disturbances such as voltage dips, over voltages and their effects can range from the annoying, such as PC shutting down or lights flickering, to serious equipment damage and industrial production being halted, which can be extremely costly.

This introductory course will explore current requirements covering power quality, typical causes of power disturbance, their likely effects and the impact they will have on operations. Parallel workshops will demonstrate power quality measuring instruments and allow hands on setting, downloads and analysis of some of the typical disturbances. The final session will examine solutions to power quality problems such as voltage regulation, harmonic distortion, and voltage dip mitigation.

The course presenters have many years of experience solving operational problems on power systems in a variety of applications in the industrial, commercial and utility sectors.
