Title: Innovations by Andrew J Philips in Geomagnetically Induced Currents

Introduction

Andrew J Philips is an accomplished inventor based in Charlotte, NC (US). He has made significant contributions to the field of electrical engineering, particularly in the measurement of geomagnetically induced currents. With a total of 3 patents, Philips has developed innovative solutions that address critical challenges in high-voltage power transmission.

Latest Patents

One of his latest patents is an "Apparatus and method for measuring geomagnetically induced currents (GIC) in high voltage transmission conductors." This invention provides a means to measure GICs that temporarily flow in high-voltage, 60 Hz power transmission conductors. The apparatus includes a securing mechanism for attachment to the conductor, a flux concentrator with a toroidal ferrite core, and a hall-effect sensor assembly that produces a voltage signal corresponding to the magnetic field. An electronics module processes this signal and transmits measurements to a local access point.

Another notable patent is for "Indicators for early detection of potential failures due to water exposure of polymer-clad fiberglass." This invention describes a composite insulator that offers early warning of impending failure due to stress corrosion cracking or other destructive conditions. The insulator is designed with a fiberglass rod surrounded by a polymer housing, which is doped with a chemical that activates upon moisture penetration. This activation results in a visible stain on the outer surface, indicating potential issues.
