Functionality of Spark Tester

KAT Controls make Spark Testers are designed for testing the insulation quality for Extruder, coiling
machine & cutting cum stripping machine for harness manufacturer. The unit is capable of performing
non-destructive integrity testing on all types of insulated cables for detecting pin-holes, cuts, slits, bare
patches etc.in cable insulation.

The spark tester consists of a High Voltage electrode unit with High Voltage transformer and an
electronic control unit which has a highly reliable solid-state structure and requires minimal
maintenance.

 

Ball chain assembly used in High voltage / Frequency Electrode unit which is in contact with the cable under test and complete periphery of the cable is covered by corona which ensures effective contact zone around the cable insulation.

This unique feature ensures that the actual voltage displayed on the meter is applied accurately and consistently to the cable surface even if the bead chains do not touch the cable form all sides. A pre-adjusted and extremely sensitive fault detection circuit detects all the faults. As compared to water immersion test this is nondestructive test.
