“The technology uses NETL’s patented electric current locator (ECL), which resolves unknown or diffuse current paths in applications where direct access to the current path is not available. To accomplish this, APS technology utilizes the Maxwell-Ampere Law, relating magnetic fields to electric currents. The ECL also leverages the Biot-Savart Law, which describes the relationship between a steady line current source and magnetic flux density at a point. This allows the technology to resolve current paths which subject to variances in the magnetic field due to superposition and geometrical issues.”
