Good to know:
Die Stoßspannungsprüfung
Where testing takes place at the device under test .
- within the winding from turn to turn
- from winding to winding
- from phase to phase
- from the winding to the laminated core
Die Stoßspannungsprüfung ist der »Tiefe Blick in die Wicklung«. Weder mit der Hochspannungsprüfung noch mit Prüfmethoden wie zum Beispiel der ohmschen Widerstandsprüfung oder der Induktivitätsprüfung lässt sich eine derartige Prüftiefe erreichen.
Diese Fehler deckt die Stoßspannungsprüfung auf.
- Insufficient insulation clearances
- insulation weaknesses
- Inadequate dielectric strength
- incorrect number of turns
- deviating winding geometry
- enameled copper wire defects
- turn-to-turn faults
- voltage-dependent turn-to-turn faults
- phase-to-phase faults
- voltage-dependent phase-to-phase faults
- Faults to frame
- voltage-dependent Faults to frame
- layer faults
- voltage-dependent layer faults
- Problems with the laminated core
- Problems with the magnetic core
- Circuit faults

So funktioniert die Stoßspannung.
Prinzipiell erzeugt das Stoßspannungsprüfgerät einen Hochspannungsimpuls mit sehr hoher Flankensteilheit.
To do this, it charges the surge capacitor integrated into the test set to the desired voltage level. As soon as the TEST VOLTAGE is reached, the test set uses a very fast semiconductor switch to connect the charged capacitor to the winding under test. This results in a resonant circuit consisting of the test object’s inductance and the charged capacitor. The impulse response at the resonant circuit is a very steep voltage rise followed by the typical voltage waveform in the form of a damped oscillation.
The very rapid voltage spike creates high voltage differences between individual and/or multiple turns within the winding. If there are any weaknesses in the insulation, the brief, high voltage difference leads to discharges. These affect the voltage waveform of the damped oscillation in such a way that it visually differs from that of an intact winding.
Using an analysis method patented by SCHLEICH and various algorithms, the tester analyzes the difference between normal and abnormal voltage and current waveforms. Based on these analyses, the tester automatically determines whether a winding GO (GO) or defective (n.GO).
So wird die Stoßspannungsprüfung durchgeführt.
Whether manual, semi-automatic, or fully automatic: SCHLEICH's surge voltage testers allow you to complete any test task quickly and efficiently run.
Our devices are all designed according to the "KISS principle". That is, following the motto: »Keep It Simple and Smart«. This principle serves as a guiding theme for all SCHLEICH products.
A manual test is performed by connecting Kelvin clamps to the device under test.
Für die Anforderungen von Produktionsbetrieben bieten sich eher teil- oder vollautomatisierte Stoßspannungsprüfgeräte bzw. Stoßspannungsprüfautomaten an. Hierzu sind die Prüfgeräte mit einem Relais-Umschaltfeld (Relais-Matrix) ausgestattet. Diese schalten die Stoßspannung automatisch an die gewünschten Prüfpunkte.
Test systems of this type have up to 100 test connections, depending on the application.
Sicherheitsmaßnahmen bei die Stoßspannungsprüfung beachten!
Das Arbeiten mit Stoßspannung ist nicht ungefährlich. Deshalb sind entsprechende Sicherheitsvorschriften und Maßnahmen zum Berührungsschutz unbedingt einzuhalten.
In R&Dspace and in repair work, it is often unavoidable to work on an open, unprotected device under test without built-in contact protection. In production, protective measures such as test hoods, test booths, light curtains, or barrier chains are typically used.
Die Anforderungen an ein Standard-Stoßspannungsprüfgerät.
SCHLEICH surge testers typically feature the following characteristics:
- standard-compliant testing
- High voltage slew rate
- very fast measurement technology with high resolution
- Fully automatic switch-over between the various winding terminals of the test object
- fully automatic analysis
- Patented evaluation method
- Integrated test plan and test result memory
- Development, Production, and Service – Made in Germany
SCHLEICH surge testers are based on over 30 years of experience and pioneering work. From the outset, the measurement technology was designed digitally, not analog. Fundamentally, the latest technologies are always applied.
So finden Sie das passende Stoßspannungsprüfgerät.
Sofern Sie an Ihrem Prüfobjekt ausschließlich Stoßspannungsprüfungen durchführen möchten, sind Sie mit einem Einzelprüfgerät gut beraten. Es enthält die Stoßspannungsprüfung und ohne zusätzliche Extrakosten auch immer die Isolationswiderstandsprüfung und PI-Messung.
If the device under test requires additional tests, we recommend our combination testers/multifunction testers. These allow for the integration of supplementary test methods such as partial discharge, high voltage test AC—plus partial discharge if needed—ohmic Resistance test, rotating-field testing, and other functions. The fully automatic test method switching ensures that no test leads need to be manually reconnected to the device under test during the test.
Thanks to the intuitive and convenient operation of our surge testers, every test is performed quickly, precisely, and cost-efficiently.
