About
D. D. Stewart is a researcher specializing in high-voltage engineering and non-invasive electric field sensing, with a particular focus on electro-optical (EO) probe technology. Their work centers on developing autonomous, high-precision methods for mapping electric fields in complex geometries and validating these measurements through finite element analysis (FEA) models. Stewart's major contributions include pioneering the use of robotic arms and automatic data acquisition units to perform electric field mapping in known high-voltage geometries, such as plane-plane and sphere-sphere configurations, as reported in their 2024 paper (3 citations). They have also advanced condition monitoring of power systems by demonstrating that electric field mapping can reliably detect and locate shorted units in cap and pin insulator strings—a critical functional element in transmission towers—as detailed in their 2025 work (2 citations). Though early in their career, Stewart's innovative integration of EO probes with automation and FEA validation represents a significant step toward safer, more efficient maintenance of high-voltage infrastructure. Their research holds promise for reducing manual inspection risks and improving grid reliability.
