Manual probe carriage system and method of using the same
First Claim
1. A probe support carriage for use during probing an electrical device, comprising:
- a body having a first end and a second end;
means for supporting and positioning said body;
a plurality of flux sensors operatively connected to and extending from said body via a plurality of probe extension pieces, each flux sensor of said plurality of flux sensors comprising a probe having a core structure of a material having high initial permeability and high resistivity characteristics, and a coil structure separate from said core structure and disposed with said core structure, said probe adapted to being supported so that a sensing portion of said core structure is maintained in a contact-free spaced relationship between a predetermined surface of the electrical device and said sensing portion of said core structure; and
a position sensor adapted to determine position along a longitudinal axis of the electrical device.

Abstract
A probe support carriage for use during probing an electrical device includes a body, means for supporting and positioning the body, a plurality of flux sensors and a position sensor. The body has a first end and a second end. The plurality of flux sensors are operatively connected to the body. Each flux sensor includes a probe having a core and a coil. The core includes a material having high initial permeability and high resistivity characteristics. The probe is adapted to being supported so that a sensing portion of the core is maintained in a contact-free spaced relationship between a predetermined surface of the electrical device and the sensing portion of the core. The position sensor is adapted to determine position along a longitudinal axis of the electrical device.

17. A method of detecting an electrical fault in an electrical device comprising:
-
extending plurality of probes from a trolley via a plurality extension pieces, each probe of said plurality of probes having a solid core structure and a coil structure separate from said solid core structure and disposed with said solid core structure; maintaining a sensing portion of said solid core structure in a contact-free, spaced relationship between opposed surfaces of members of the electrical device and through which a leakage flux passes; inducing energization of the electrical device to a predetermined level which is lower than a normal operating level and thus produce said leakage flux; detecting said leakage flux using said each probe at a first position; moving said trolley to a second position with respect to said opposed surfaces and detecting said leakage flux at said second position; monitoring a fluctuation in output of said each probe and detecting the fault in response to an abnormal leakage flux; and determining an axial position of said trolley within the electrical device. - View Dependent Claims (18, 19, 20)
