This session introduces the physics of lightning propagation and how a well designed system offer protection against the risk of fire.
The seminar presents the basic physical parameters of lightning step leader attachment, charge content, peak current, rate of change and energy. These parameters are used to define lightning protection levels and how that level influences the Pillars of Protection. These air terminals, down conductors, earth termination, separation distance and equipotential bonding principles are presented along with illustrative examples to help build the fundamental understanding of lightning protection.
Bonding for safety, function and surge protection is presented along with best practice examples and explanations.
Grounding and bonding are essential for lightning protection and safe electrical equipment operation. They form the columns of the earth termination system and equipotential bonding for the pillars of protection. These principles are presented along with design details and both good and bad examples. The concepts of separation distance between metal elements and surge protection of energized wires are presented to show how these concepts all stich together.
The seminar will introduce surge protection design, device selection, application, earthing design and site inspection to be sure it is installed correctly.
Electrical surge protection and earthing are considered in relation to their important role in the pillars of protection. Detailed examples of electrical power and data communications protection are provided. Earthing system design and installation examples are presented to give real world insight into the problems observed and how that will impact critical operations.
This seminar covers site inspection methods to evaluate earthing, bonding and surge protection problems with real world examples.
Mysterious problems with tripping and electronics failures can often be traced back to broken grounding wires or lack of surge protection. This session will offer methods and examples of site inspection techniques that are useful to determine root causes of site problems. Several examples of both bad mistakes and best practice configurations are presented to help build basic inspection skills. The obvious problems can sometimes be the hardest to find and this session will help create a solid background for trouble shooting.
This session will show several useful examples of meaningful/accurate site measurements and use in calculations/designs. Apart from that it will serve as a primer for deeper dive into specific disciplines of earthing and soil measurements.
The following areas are covered:

The features and benefits of the DEHNdetect lightning detection product line is presented.
A basic problem has emerged in the wind turbine industry based on the nature of lightning strike effects. Long duration strikes with relatively low amplitude ICC events are being measured and shown to cause damage that is otherwise not recorded. The DEHNdetect can now be used to both record these events and show customers, operators and owners where the source of damage is and what specific event caused it. The system employs sensors and converters to both log the data and store it on the cloud for easy retrieval. The data can be used to prove the source of damage and schedule maintenance in a timely and efficient manner.

Many solar farms have been constructed that suffer from a fundamental flaw in the earthing system.
Although the earthing is safe for DC power generation and 60Hz power transmission, these plants do not endure the transient environment.
The symptoms appear as unrelated inverter tripping or similar faults that cause disruptions or reduction of generation capacity.
But the actual problem is not in the inverter at all, it is a fundamental flaw in the earthing connections that directs all fault and transient energy directly into the inverter.
Earthing Modeling Software is used to simulate the problem and design the solution to meet IEEE 80 requirements. Actual field installations have shown 80 to 90% reduction of events as per design goals.
