Innovations, technical leadership and a patented surge voltage evaluation methods characterize the MTC2 surge voltage testers of the 6th generation. You can choose from a finely graded tester variety from 6 kV to 50 kV.  Based on 25 years of experience, extensive know-how and a consistent optimization you purchase a state-of-the-art surge voltage tester. The housing variants are ideally suitable for universal usage and almost every application. Whether stationary application or mobile operation – the MTC2 provides the right solution.

Winding tests in its purest form.

Intuition – Function – Perfection.

The MTC2 is our premium surge voltage tester – no other tester offers such a diversity of features. With the MTC2 you inspect coils, stators, armatures and all kinds of windings according to the latest state of the art – uncompromising and precise.  Innovations, technology lead and a patented analytical method for surge voltage characterize the MTC2-surge voltage testers of the 6th generation.  A finely graduated variety of testers from 6 kV up to 50 kV  is available.  Based on 25 years experience, extensive know-how and consistent optimization you get THE “state-of-the-art surge voltage tester”.


What makes the MTC2 so special?


4 connection leads offer the possibility to contact all relevant winding connections at the same time. The 3 phase connections and the neutral point are connected to the 4 connection leads.  In this way it is possible to achive a unique test accuracy. 


Automatic test method switch-over - As soon as the test object is connected, the MTC2 automatically measures at all 4 connections. Thanks to the integrated test method switchover, there´s no need for manual re-clamping. This saves time and avoids mistakes.


Advanced surge voltage - The surge voltage test with standard-compliant rise time leaves no defect undetected. Modern, automatic evaluations facilitate the fault analysis.


Optional partial discharge test with surge voltage - The innovative, standard-compliant partial discharge test can easily be integrated. It gives you information about critical insulation weaknesses and the suitability for operation with frequency converters.  SCHLEICH pursues two strategies to obtain good test results at stators as well as at entirely-assembled motors: Measurement via coupler in the measuring lead (perfect for motors) and measurement via antenna (perfect for stators).


Optional precise resistance measurement in 4-wire-technology - To achieve precise measuring results by comparing the three phases´resistances , the resistance is measured in 4-wire technology.  Of course, the 4-wire technolgy is also applied by means of the automatic test method switchover!


Optional high-voltage test with AC - In addition, you can also perform a high-voltage test with AC.  Of course,  the automatic test method switchover is also applicable in this case. 


Optional rotor- / stator test - The measuring technology allows you to find faults in rotors or stators and to detect broken bars in the squirrel-cage rotor.
