A Dissipation Array Air Terminal (DAT) is a lightning protection device designed to reduce the likelihood of direct lightning strikes by dissipating the local electric field through multiple pointed electrodes.
A Dissipation Array Air Terminal (DAT) is an advanced lightning protection component consisting of multiple sharp conductive points arranged in an array. The design promotes continuous corona discharge under high electric field conditions, with the goal of reducing electric field intensity around the protected structure. DAT systems are used in specialized lightning protection applications for critical facilities.
Unlike conventional air terminals that are intended to intercept lightning strikes, DAT systems are designed around the concept of electric field dissipation. Their use and performance may depend on local engineering standards and project specifications.
