A Real-Time IR-Fusion Switchgear Contact Monitoring System (SCMS)
IEEE Access, 2017 In this paper, a real-time monitoring system for switchgear contacts (switchgear contact monitoring system) with continuous thermal monitoring is presented instead of infrequent scanning with a handheld infrared (IR) camera or IR window.

High Voltage, EarlyView.ABSTRACT The optical emission spectra (OES) reflect the presence of excited states in the gaseous discharge, which are directly linked to the decomposition characteristics of insulating gases. In this study, a pin/rod–plate discharge reactor driven by either a high‐voltage direct current (DC) generator or a pulsed generator was developed to establish ...
