ABSTRACT:
Apparatus, methods, and systems improve spark testing of insulated cables. According to embodiments described herein, a spark tester includes a conductive housing having an entryway, an exit, and a test chamber therebetween. The spark tester utilizes spring electrodes connected to an adjustment ring at one end of the housing and to a fixed structure at the opposite end of the housing. The adjustment ring is rotated such that the spring electrodes wrap around the test cable, contacting the test cable on all sides throughout the test chamber. The housing also includes an electrical contact for receiving and distributing a voltage across the housing and the spring electrodes. As the test cable is drawn through the spring electrodes, the grounded conductors within the test cable are monitored for a voltage spike, indicating an insulation defect that allowed a discharge from the spring electrodes to a test cable conductor.
