MTC3 winding test systems are fully automatic, high-end testing devices designed for a wide variety of wound products in development, production, and testing laboratories.

The MTC3 test systems are fully configurable to your requirements and offer high-end technology for complex testing tasks. Using state-of-the-art technology, they test coils, stators, electric motors, generators, and transformers from 0.1 W to 500 MW.

The performance potential of the MTC3 testing systems is based on the interplay of all strengths: user-friendliness, measurement accuracy, database concept – all components are perfectly coordinated based on innovative technologies.

As one of the first test equipment manufacturers, SCHLEICH consistently relied on the integration of a PC for measurement value processing, test sequence control and data storage for MTC3 test systems at an early stage. This many years of system experience of our technicians and engineers provides the operator with a sophisticated test system with extensive software. Many useful software tools are part of our standard scope of delivery.

Our fully automated MTC3 test systems reliably and quickly check your windings for potential insulation faults thanks to the patented SCHLEICH impulse voltage test. Once the test object is fully connected, the test runs with automatic switching of connections and test methods. The MTC3 evaluates each predefined test step. At the end of the entire test sequence, a clear and reproducible pass/fail result is provided.

Hardware and software are developed and manufactured in-house by SCHLEICH. The software and database are based on the latest, proven ^Microsoft® technology. Our diverse innovations continually set technological standards for modern test benches running ^Windows® . The system provides the operator with a clear, concise overview of the test, while the setup technician has extensive input and configuration options at their disposal.

Quality assurance is also a key focus. A comprehensive statistical analysis is integrated into the testing system, leaving virtually nothing to be desired. Finally, you can document the tested quality for your customers with a variety of different report printouts.

The MTC3 testing systems are manufactured according to your requirements based on the SCHLEICH MODULAR CONCEPT. The necessary testing methods can be selected from the pool of available options as needed.

Whether for manual or automatic single, double, or multi-station testing – with or without a test hood or test table – or for testing in automated production lines, the MTC3 is the ideal solution. There are no limits to the MTC3's versatility. Thanks to its enormous hardware and software flexibility, the testing system can be tailored cost-effectively and precisely to your specific requirements.

• Partial discharge test with high voltage AC 
• Resistance testing from µΩ to 100 kΩ
• Room temperature compensation
• Direction of rotation check of the rotating field 

The MTC3 is available in various standard configurations. The configuration is tailored to the specific application.

Starting with the basic unit and its standard features, you determine the number of required winding connections and temperature sensors. You then select further testing methods from the available options.

If no suitable solution for your application is listed here, we will gladly put together a customized solution for you based on the SCHLEICH MODULAR CONCEPT. More is always possible!

Based on the SCHLEICH MODULAR CONCEPT, the MTC3 testing systems offer a wide range of combinations of various safety and functional testing methods. Your specific testing requirements determine the testing methods you select from a large pool of options.

Whether you need one test method or a variety – you determine the configuration! For example, your MTC3 can be configured as a specialized high-voltage tester with numerous test outputs. For more complex testing tasks, you might require a combination of all possible test methods.

The SCHLEICH MODULAR CONCEPT allows you to assemble precisely the testing equipment you need. This is achieved not only by installing various individual testing devices in an oversized test rack, but also by integrating all tests into a compact, modular housing. The housing size is determined by the type and scope of the various tests.

The flexibility of the MTC3 test systems is evident not only in the housing but also in the number and arrangement of the test device's connections. With the 19" container and the 19" industrial cabinet, the measurement connections can be mounted on any side of the test device. This allows us to meet all spatial requirements.

Every testing device embodies the experience gained from thousands of installations. At SCHLEICH, this experience is consistently, passionately, and without compromise applied.

That is "customer-centric technology."

Despite their very compact design, these testers offer a wide range of testing options in a single housing. The combination of testing methods based on the SCHLEICH MODULAR CONCEPT therefore also incorporates a modular housing design.

Depending on your requirements, your application can be housed in a compact benchtop unit, a 19-inch rack-mount unit, a 19-inch enclosure, or a 19-inch industrial cabinet. To ensure the proper and safe installation of the test equipment, we use custom-fit enclosure components from renowned German manufacturers as well as components manufactured in-house.

The software is based on the Microsoft ^Windows® operating system. The optimized user interface enables user-friendly execution of the test, creation of test plans, printing of test reports, and statistical evaluation of the tests.

In automatic mode, all tests are performed fully automatically. The measurement results are continuously displayed and evaluated during the test. The clear pass/fail indicator visualizes the automatic evaluation.

The test sequence is edited by simply adding or removing test steps. This allows the test sequence to be optimally adapted to different requirements. Each individual test step can be quickly edited and changed by double-clicking on the respective test step.

The comprehensive integrated user management system ensures that only authorized personnel can make these changes. Additional work instructions make the MTC3 the perfect ISO 9001-compliant testing instrument.

Test plans and test results can be stored locally or on a central server. This ensures high data security and optimal data exchange between different testing systems.

The MTC3 works optimally in all network infrastructures. This characteristic provides the ideal platform for collecting, managing, analyzing, and distributing information.

The database uses proven and widely used technologies from ^Microsoft® .

The testing devices can also be ideally integrated with ERP, PPS, and CAQ systems. We offer tried and tested, customer-optimized standard solutions for all requirements.

The Windows® ^- based MTC3 test instruments can be operated in network topologies of any complexity. You can install any number of test instruments at different company locations worldwide, all of which operate with a central server database for test plans and results. Our extensive experience in globally networking our test instruments gives you the assurance of being able to offer the same product quality regardless of the production location.

Naturally, all test plan, printing, labeling, and statistical tasks can also be performed on the individual testing devices. However, to avoid disrupting the production process, it is advisable to use separate workstations for this purpose in networked systems. These workstations run the same software as the testing devices to ensure maximum ease of use.

The labels can also be stored centrally on a server. The testing device loads the appropriate label according to the respective test plan and transfers the data to a thermal transfer printer after the test. The labels can also be designed according to your specifications.

In the case of remote maintenance (via remote access), we can temporarily connect to your network and directly access the individual test device as needed. We can then view the screen content of your test device directly from our location. With your permission, we also have access to your mouse and keyboard. Naturally, this work is only carried out in consultation with you and requires separate access authorization from you.

The MTC3 is ideally suited for integration into automation systems. It offers a huge variety of interfaces for communication with a wide range of automation systems.

Traceability allows you to obtain clear and complete information about the entire manufacturing process, even after the fact. In the event of quality problems during production or after delivery, traceability enables you to react appropriately.

We provide answers to the following questions:

• Which end products, assemblies, and components are affected?
• Which customers own the end products, assemblies, and components?
• Which assemblies and components are used in the final product?
• When, where, and by whom were which parts processed during the manufacturing process?
• Who manufactured or supplied the assemblies and components?
• What test results are available for the individual assemblies and the final product?

Answering these questions requires the unique identification of each component, assembly, and finished product with a number or code. Additional information such as customer number, supplier number, batch number, etc., may be necessary for improved traceability and searchability.

MTC3 inspection systems are capable of capturing these markings and additional information, e.g., via barcode input, and storing them, along with the inspection results, the inspection date, and the inspector's name, in the inspection device's database or on the network. This information allows for later tracking of where, when, and by whom components were processed or delivered during the manufacturing process.
