Spark tester AST L / AST H / DST - Overview

Dielectric Testing with the Spark Test Principle (Dry Test):

In-line fault testing on single conductors and jackets during the extrusion or rewinding process has become standard procedure today. ZUMBACH® Spark Testers can be used to test the most diverse range of cable products as per international standards, like IEC 62230, UL 1581, UL 2556 and further standards. Data ports allow for easy integration with quality control systems (e.g. USYS).

Important Features:

  • Wide range of test voltages:

    • 2…40 kVac / 50...120 Hz (adjustable)
    • 0.5…15 kVac / 3 kHz
    • 1…28 kVdc/50 Hz
  • Fault detection according to requirements given in IEC 62230
  • Wide range of electrodes up to a diameter of 200 mm (7.8 in.) and in compliance with UL 1581, UL 2556 and further standards

Fault Detection on Plastic Tubes

The new direct current spark testers of the series DST 28A are designed to detect faults in the wall of tubes, corrugated tubes or similar products with insulating material.

Various ring electrodes are available, best suited for a large range of applications.
