Types of Surge Arresters

Published by Lorenzo Mari, EE Power – Technical Articles: Types of Surge Arresters, December 18, 2020. Learn about the most common types of surge arresters used to protect against transient overvoltages and lightning strikes. Surge arresters introduce shunting resistance to the ground when a surge appears, absorbing energy from the surge without the voltage becoming excessive.Continue reading “Types of Surge Arresters”

Substation Protection Against Transient Overvoltages and Lightning Strikes

Published by Lorenzo Mari, EE Power – Technical Articles: Substation Protection Against Transient Overvoltages and Lightning Strikes, December 11, 2020. Learn how surge arresters protect power substations against lightning and switching overvoltages. Transient overvoltages are typical of power systems. The sources of overvoltages are direct or nearby lightning strikes, switching operations, electromagnetic pulses, and electrostatic discharges.Continue reading “Substation Protection Against Transient Overvoltages and Lightning Strikes”

Influence of HV LC Filter on Lightning Overvoltages in Gas-Insulated Switchgear Substations

Published by Marcin SZEWCZYK, Tomasz KUCZEK, Mariusz STOSUR, Wojciech PIASECKI, Marek FLORKOWSKI, Marek FULCZYK, ABB Corporate Research Center in Krakow, Poland Abstract. In the present paper simulations of the propagation of lightning overvoltages in a typical HV GIS substation are presented. The influence of HV LC filter on maximum overvoltages peak values was analyzed. Additionally,Continue reading “Influence of HV LC Filter on Lightning Overvoltages in Gas-Insulated Switchgear Substations”

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: carelabz.com 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”
