Abstract
An insulation inspection system includes: a set of input terminals; a brush; a circuit connected to the set of input terminals, the brush, and a part being inspected, where the circuit includes at least one pair of resistors and a capacitor; and a control module configured to detect when a short circuit exists between a conductive element of the part and one or more conductive bristles due to insulative material missing on the part and as a result the one or more conductive bristles of the brush contacting the conductive element of the part.
Claims20
An insulation inspection system comprising:
- a set of input terminals;
- a brush;
- a circuit connected to the set of input terminals, the brush, and a part being inspected, wherein the circuit comprises at least one of a pair of resistors and a capacitor;
- and
- a control module configured to detect that a short circuit exists between a conductive element of the part and one or more conductive bristles due to insulative material missing on the part and as a result the one or more conductive bristles of the brush contacting the conductive element of the part.
An insulation inspection method comprising:
- connecting a lead to a part to be inspected;
- moving a brush across a portion of the part or moving the part relative to the brush;
- detecting via a circuit a drop in voltage across a set of input terminals, wherein the circuit is connected to the set of input terminals, the brush, and the part, and wherein the circuit comprises at least one of a pair of resistors and a capacitor;
- and
- determining whether the drop in voltage is indicative that a short circuit exists between a conductive element of the part and one or more conductive bristles of the brush due to insulative material missing on the part and as a result the one or more conductive bristles of the brush contacting the conductive element of the part.
