The latest hardware technologies paired with state-of-the-art .NetCore software come into play. This significantly increases the accuracy of the individual test methods and of the measurement speeds.
The MTC2 R7 is the high-end device for testing windings, coils and armatures.
SCHLEICH PATENT: |
|
The surge voltage test is capable of a pulse frequency of up to 50 Hz. The test time of the partial discharge inception voltages can thereby be reduced by up to 75 %. | |
SCHLEICH PATENT: | |
The SCHLEICH „peak to peak“ method for the detection of voltage-dependent winding faults has been completely revised and enables highly sensitive fault detection even in the case of coils with very high numbers of windings, connected in series or parallel. |
As a mobile version with carrying handle or as a built-in version in a 19″ industrial rack. The MTC2 R7 fits your needs.

A test device can be as good as it is – it must fit into an established infrastructure and extend and refine existing possibilities. For this reason, the discreetly recessed connection panel of the MTC2 R7 standard device has been placed on the side to make it easily accessible. Whether you operate the device on a table or standing on the floor, all connections are conveniently accessible at all times.
The standard device:
*the standard device has built-in SHOCK absorbers to help protect the measurement equipment against vibrations.

All connections are now located on the rear panel. This makes it very easy to integrate the MTC2 R7 into a 19″ rack. For optimal remote control, the device in this version has an additional PLC I/O interface, which is always installed as standard. Additionally RSS232, Ethernet or various field buses are expandable (Profinet, EtherCat or ProfiBus)..

5 test leads give you the possibility to contact all relevant winding connections at once. The 3 phase connections as well as the star point (if available and accessible) are connected with 4 test leads. The fourth test connection at the star point gives you a unique increase in test accuracy. The fifth test connection is connected to the stator/motor housing. It is required for the insulation test between the winding and the laminated core.
After connecting the device under test, the MTC2 R7 automatically tests on all 5 clamps. Thanks to the integrated test method switching, you no longer have to reconnect any connections by hand. This saves time and avoids errors.
Do you usually always need more than 4 measuring connections, e.g. to contact additional sensors or unconnected devices under test? Then an extension of the MTC2 R7 to a total of 8 measuring connections + frame is possible.
The surge voltage with standard-compliant edge steepness leaves no fault undetected. Modern automatic evaluations facilitate the subsequent fault analysis for you.
The MTC2 R7 features surge voltage testing with a pulse frequency of up to 50 Hz. This results in a considerable decrease in test cycle time, which is particularly advantageous in combination with the partial discharge inception voltage measurement (RPDIV). (optional extension)

The standard-compliant PD test can also be integrated. It gives you information about critical insulation weaknesses and the suitability for operation with frequency converters. Here SCHLEICH pursues two strategies to obtain good measurement results: both on the stator and on the fully assembled motor:
Until now, the partial discharge inception voltage measurement was a particularly time-consuming test. For a 3-phase device under test, for example, this could take 8.5 minutes (depending on the parameterization of the test steps). With the new, patented surge voltage test of the MTC2 R7, it is possible to reduce test duration by approx. 75 % (with the same parameterization of the test steps). (optional extension)

To achieve highly accurate measurement results for your resistance measurement comparison between the 3 phases, the resistance test is performed using four-wire technology. This automatically compensates for the resistances in the test leads. In addition, the MTC2 R7 detects the room temperature to compensate for any temperature influence. The resistance test including temperature compensation is always a part of the MTC2 R7.
By using SCHLEICH Kelvin clamps, compensation of the contact resistances at the clamping points to the winding is ensured. Only in this manner resistances of less than 10 Ω can be measured with high precision.

In addition, the AC high voltage test can also be applied. It is also automatically switched to the device under test via the automatic test method switchover. (optional extension)

To check the rotating field of a stator, the MTC2 R7 simulates a rotating field supply at the three winding connections of a stator, connected in a star or delta connection. A special probe placed in the stator detects the sense of rotation which is then evaluated by the MTC2 R7. (optional extension)

A software assistant offers optimized support for the armature test. It guides you through the test so that no lamella will be missed. The manual test is performed using test probes or an armature adapter. The automatic test uses a fully automatic contacting adapter. Either the armature or the contacting adapter rotates to contact the lamellae precisely and reliably. An automatic position adjustment is built in for this purpose. Ask us – we can supply you with the complete solution to suit your armatures. (optional extension)

The new software is based on state-of-the-art .NET technology and has been completely redesigned. The MTC2 R7 features modern and clear views that enable intuitive operation. To ensure operation via touch during mobile use or in the workshop, a variety of settings can be displayed enlarged. Coupled with a big touch keyboard, the software allows operation even without mouse and keyboard.

The many connection capabilities of the MTC2 R7 allow for a custom setup of the test area. Whether a warning and result light is used or a safety circuit (e.g. from a protective fence or test cover) is to be integrated, the MTC2 R7 allows for this with ease.
The MTC2 R7 comes ready for instant measurement. After a few motor parameters have been entered, the test can start. Either an autotest can be performed based on the entered motor parameters or a user-defined test sequence can be initiated.
Virtually all motor data including a picture can be stored. This simplifies the retrieval of motor data and the corresponding measurement results. The motor data are also printed directly on the SCHLEICH standard protocol in connection with the measurement results.
Using special test probes and an armature booster, the rotor is tested according to the lamellar method. This usually involves testing between two adjacent lamellae. A quarter or half circle measurement is also possible. The built-in armature assistant software reliably guides the operator through the test.

The MTC2 R7 can easily be incorporated into a production line. The housing measurements are based on a 19″ rack, which allows for seamless integration of the test device. The added interfaces enable full remote operation of the device by a PC control system.
For different types of devices under test, almost any number of test sequences can be stored in the MTC2 R7. These test sequences can be accessed and launched through an interface.
All test results can be accessed through an interface and can thereby be stored in a central database via the control PC. It is also possible to store the results locally on the test device or directly in a network.
