The risk of lightning strikes on people, structures, and businesses is increasing. Two major factors are driving this trend: bigger cities and global climate change. In the US alone, total lightning-related damage and disruption currently cost $8 to $10 billion annually, rising at nearly 20% per year. Yet for risk mitigation and damage avoidance, cost-effective... Read more
This presentation will focus On The Benefits Of Polymeric Armored Cables, And Their Applications. Medium and high voltage polymeric armored cables are much different than low voltage polymeric armored cables. Therefore, the presentation is split into two parts to go over each type individually. The key benefits of medium and high voltage polymeric armored cables... Read more
The presentation provides information on the types of grounding systems, associated benefits and disadvantages, the transition to resistively grounded systems, and the sizing of neutral grounding resistors for typical applications. This includes system charging current, resistor let-through current, duty cycle, and associated information in relation to NEC and CSA requirements for impedance grounding systems. Lastly,...
