Lightning Transient Overvoltage Evaluation

Published by Electrotek Concepts, Inc., PQSoft Case Study: Lightning Transient Overvoltage Evaluation, Document ID: PQS1205, Date: January 26, 2012. Abstract: This case study presents a wind plant substation lightning transient overvoltage evaluation. A high-frequency transient model was created to simulate the lightning transients and resulting overvoltages and arrester energy duties. A high-frequency model was required toContinue reading “Lightning Transient Overvoltage Evaluation”

What is Protective Device Testing and How is it Done

Published by Carelabs (Carelabz), Website: Equipment applied to electric power systems to detect abnormal and intolerable conditions and to initiate appropriate corrective actions. These devices include lightning arresters, surge protectors, fuses, and relays with associated circuit breakers, reclosers, and so forth. From time to time, disturbances in the normal operation of a power system occur.Continue reading “What is Protective Device Testing and How is it Done”

Learn What is the Purpose of Lightning Arrester and Why is Testing Necessary

Published by Carelabs (Carelabz) A Lightning Arrester, Surge arrester or Line arrester is a device used on electrical power systems and telecommunications systems to protect the insulation and conductors of the system from the damaging effects of lightning. The typical Lightning Arrester has a high-voltage terminal and a ground terminal. When a lightning surge (or switching surge) travelsContinue reading “Learn What is the Purpose of Lightning Arrester and Why is Testing Necessary”
