EMI SURGE AMP LIGHTNING PROTECTION FOR SUBSTATION CABINETS

Lightning strike conductor relay protection

Lightning strike conductor relay protection

The lightning strike directly struck the Phase A conductor (shielding failure) and discharged current into it. The paper examines and explains the response of two different line current differential protective relays to this event that was inside their zone of protection. INTRODUCTION On February 19, 2017, powerful storms and tornadoes swept through the state of Texas, damaging homes and properties in. On the following pages, you will find comprehensive information and valuable tips on protecting your electrical system and equipment. Electrical protection refers to the systems and devices designed to detect and isolate electrical faults such as overcurrents, short circuits, ground faults, and lightning strikes to prevent damage, fires, and ensure safety in industrial and commercial power systems.
