WIRE TEST METHOD AND APPARATUS
A wire testing method and apparatus tests wire (30) in-situ in a rigidly installed state, such as an aircraft (100). Stray currents are compensated by an apparatus for rapidly switching the excitation voltage and ground. The apparatus outputs a stray current signal (721), a detected current signal (...

| Zusammenfassung: | A wire testing method and apparatus tests wire (30) in-situ in a rigidly installed state, such as an aircraft (100). Stray currents are compensated by an apparatus for rapidly switching the excitation voltage and ground. The apparatus outputs a stray current signal (721), a detected current signal (731), and a difference signal (830) indicative of a measurement with the stray current signal removed. |
