Spark Testers

KatCon make Spark Testers are designed for testing the insulation or sheathing of the cable during extrusion, winding processes. The unit is capable of performing non destructive integrity testing on all types of insulated cables detecting pinholes, 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 H.B. Electrode Unit which is in contact with the surface of the cable under test and combines with the resulting corona in H.F. Spark testers to form an extremely effective contact zone around the cable insulation.

This unique feature ensures that the actual voltage displayed on kV meter is applied accurately and consistently to the cable surface even if the bead chain do not touch the cable from all sides. A preadjusted and extremely sensitive fault detection circuit detects all the faults in the cable insulation at proper voltage setting. These spark tester are able to detect all the faults which are detected in water immersion testing of cables.

The interlock with the electrode unit cover protects the operator from accidental contact with the electrode.
