How To Measure Quality

Spark Tester

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 EN, BS, CEN/CENELEC, CSA, NEMA, UL, UTE, VDE, and so on, thanks to the multitude of electrodes, test voltages, and frequencies available. Data ports allow for easy integration with quality control systems (e.g. USYS).

Important Features:

Robust, durable
Accurate, repeatable
In compliance with standards
Selective
Optimum operation
Available in all sizes

CALIBRATOR SP - Vital for Quality Assurance and ISO 9000

Used for periodic verification and calibration of AC, AC-HF, DC, and Impulse Spark Testers of any model and any make. Complies with all Spark Tester standards.
Test voltage and short circuit current measurement can be certified.

Important Features:

Measures all existing categories of test voltages
Measures test voltage, short circuit current, frequency, fault sensitivity
Easily accessible on the line, thanks to compact and ergonomic design

Fault Detection on Plastic Pipe

Thanks to a special AST high-voltage test instrument, rigorous quality requirements, as the apply to floor heating pipes, chemical pipes, gas pipes, and others, can be guaranteed without a problem. The instrument detects the smallest, practically invisible faults, like pinholes and microscopic cracks.

Diameter Range: 14...25 mm (.55...1 in.)
Wall Thickness: up to 2.5 mm (.1 in.)
Test Voltages: 0...25 kV AC

Control and Display

Several operating units may be connected to the various electrodes for display of the test voltage, number of faults, alarms, etc. All spark testing systems can be interfaced directly or via existing data port to a central processor, PLC or to a USYS processor and, therefore, can be controlled remotely. AST-HF and SPARKMASTER DST electrode units can also be controlled directly through PROFIBUS DP or serial RS connections. An additional control unit (RI) offers this option for the AST L Spark Tester as well.
