For remote control, these device variants have an additional PLC as standard. In addition, the devicescanbeexpandedwith additional interfaces and fieldbuses.

Alles dreht sich um das Prüfobjekt:
Die neue Software wurde komplett überarbeitet und basiert auf moderner .Net-Technologie. Das MTC2 R7 präsentiert sich mit modernen und übersichtlichen Darstellungen, die eine intuitive Bedienung ermöglichen. Um die Bedienung per Touch im mobilen Einsatz oder in der Werkstatt zu gewährleisten, können viele Einstellungen größer dargestellt werden. In Verbindung mit einer großen Touch-Tastatur kann die Software so auch ohne Maus und Tastatur komfortabel bedient werden.

The test object database provides an optimal overview of each device under test that has been created. In addition to an overview of the individual assigned parameters such as manufacturer, serial number, and type, all test results are also test results .

Any number of test objects/test object types can be created in the software. Additional information can now be assigned to these:

• Nameplate information
• Images of the type plate or the test object 
• Location information
• Log entries for documenting any information
• Multiple test plans, e.g.:
  Incoming test
  Outgoing test
  Type test
• test results

With the five test leads of the MTC2 R7, all relevant winding connections can be contacted simultaneously. The three phase connections and the star point (if available and accessible) are connected with four test leads. The fourth test connection star point provides a unique increase in test accuracy. The fifth test connection connected to stator. It is laminated core for the insulation test the winding and laminated core .

Do you typically require more than four test connections, e.g., to connect additional sensors or unconnected test objects? If so, the MTC2 R7 can be expanded to a total of eight measurement connections + body.

The automatic test method switch-over

After connecting the test object, the MTC2 R7 automatically tests all five terminals. The integrated test method switch eliminates the need for manual reconnecting of the terminals. Our test method switch ensures fast and automatic switching between the different test methods. Since the voltage differences between the test methods can be very large, the reliability of switch-over is switch-over . A Resistance test 3 V is device under test to the device under test just as reliably as a high voltage test 15 kV. Without compromise!

For test objects with multiple connections, it is more economical to connect all connections of the test object to the test device immediately. The test device then performs all tests between all connection points fully automatically. This procedure reduces the required cycle time and thus the costs of a test and avoids errors. The switch-over the different connections is realized by flexible switching matrices.

Partial discharge testing at surge test

– Optional extension –

Partial discharge testing is used to check the winding quality of wound products. Essentially, the aim is to detect quality defects in windings that cannot be identified using conventional high voltage test surge test . 

The coupling technology combined with high-frequency filter technology makes the system extremely resistant to interference. This makes it ideal for use in the field or in manufacturing.

The test is performed either manually or fully automatically. In manual mode, the operator increases operator voltage monitoring the partial discharge signal. 

Automatic operation enables fully automatic analysis of all three phases via a test sequence. The following values are determined for each phase: 

• PDIV (application voltage) 
• PDEV (breakdown voltage)
• RPDIV (repeated insertion voltage) 
• RPDEV (repeating dropout voltage) 

It is not necessary to run the entire ramp. IfGO quickGO between GO n.GO is required during production, the patented 50 Hz high-speed test can run as an option. Alternatively, a fixed TEST VOLTAGE can be TEST VOLTAGE .

insulation resistance test

The insulation resistance test integrated in the basic unit is specialized designed specialized testing electric drives. The TEST VOLTAGE automatically test lead to the test lead , which is also Resistance test for the surge voltage and Resistance test . It is not necessary to reconnect the device under test the individual measurements. The switch-over fully automatic up to a TEST VOLTAGE 50 kV in the test device.

The software offers preconfigured test sequences for PI, DAR, high-voltage DC, MegaOhm, and step voltage. In conjunction with the new fully automatic ramp time determination, operation has been greatly simplified. In order to optimally configure the test device for special applications, all parameters can also be set separately. This includes the following functions, among others:

• Separate current limits during the ramp phase and test phase
• contact control minimum current monitoring
• Temperature compensation of insulation resistance according to IEEE Std 43

Insulation resistance test with ramp

As a rule, the ramp time is defined and set ramp time device under test device under test device under test . However, it is important to ensure that maximum charging currents are not exceeded. 

Thanks to the automatic charging current detection included in the scope of delivery during the initial phase of the ramp function, the MTC2 R7 determines the shortest ramp time.

Of course, it is still possible custom the ramp function parameters. To do this, select the ramp duration and set the maximum permissible charging current as the evaluation criterion.

• Automatic charging current detection for minimal ramp time
• test time ramp and test time
• Graphical representation of current, voltage, and insulation resistance a diagram
• discharge testing is displayed and logged.

Resistance test

Even the base version of the MTC2 R7 is Resistance test base version a Resistance test . This allows phase resistances, temperature sensors (NTCs, PTCs, and KTYs), and individual coils to be tested without having to reconnect the test leads. Thanks to the integrated test method switch, testing is performed immediately and fully automatically using the test leads already device under test to the device under test .

temperature compensation

• Temperature sensor connection directly on device
• Connectable sensors:

• • room temperature sensor
  • object temperature sensor
  • pyrometer
  • Hygrometer and barometer

• Three independent input signals, each with 0–10 V or 4–20mA
• measurement range °C (32–212 °F)
• Reference temperature adjustable
• Fully automatic compensation of resistance values for copper, aluminum, and temperature sensors

Inductance and capacitance test

– Optional extension to Resistance test

The use of a capacitance measuring bridge is a thing of the past. Use the measuring bridge optionally integrated in the MTC2 R7 for high-precision measurement of inductances, impedances, and capacitances.

The following evaluation options are available:

• Comparison of the actual value with a specified set value
• Determination of the symmetry (scattering range) of all three phases

high voltage test

– Optional extension –

The high voltage test can built-in into the MTC2 R7 and is immediately switched automatically to the measuring terminals. Reconnecting is not necessary. The test is performed fully automatically via the measuring cables already device under test to device under test .

Due to the integration of the high voltage test , this extension high voltage test only available in the 19" or tabletop version. This device the device to 10 HM.

rotating field test

– Optional extension –

The rotating field stator sense of rotation test be measured and evaluated using the sense of rotation test . The test is performed without contact using a rotating field probe, which is stator into the stator or mounted on a test object holder.

The rotating field generated by an electronic source that simulates the three-phase electric motor. This test allows wiring errors in production to be detected before the electric motor is assembled.

All test results be output either immediately after the test or at a later time on the modern standard protocol. The language of the report can custom before output. Reporting is performed in accordance with IEC 61934. The standard languages are German, English, Chinese, Danish, French, Italian, Dutch, Polish, Portuguese, Swedish, Slovenian, Spanish, Czech, and Hungarian.

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

The MTC2 R7 works optimally in all network infrastructures even in its standard configuration. This feature provides the ideal platform for collecting, managing, analyzing, and distributing information.

All test object data, test plans, test results user information can be efficiently synchronized across multiple test devices. This ensures that every test device ordesktopworkstation is always up to date without the need to exchange data via an additional data carrier.

The workstation software provides you with a comprehensive overview of all test results at all times. Test plans can be conveniently edited from your office workstation.

Use the extensive configuration options to specify which data, user accesses, and results are intended for which test system and which are not.

The software allows the test device to be operated even without a network connection. This ensures continuous testing. This is necessary, for example, in the event of a network failure or when working outdoors.

The VoltageAnalyzer

The VoltageAnalyzer is used to measure surge voltage signals directly at the electric motor winding. The frequency responsespace the space DC to very high pulse frequencies inspace . This makes the VoltageAnalyzer ideal for high-precision surge voltage and partial discharge measurements. The VoltageAnalyzer measures voltages and voltage peaks directly where they occur. This can be, for example, in electric motor motor terminal board directly at the winding connections.

Voltage measurement during surge test partial discharge

It may happen that the voltage surge tester internally in surge tester device under test voltage exactly device under test the voltage device under test . This is because the inevitable line inductances and capacitances between the measuring lines can device under test the voltage curve of the surge signal on its way to device under test . The steeper the surge impulse , the more pronounced this effect is.

In order to accurately measurement the partial discharge onset voltage actuallymotor terminal board tomotor terminal board during a partial discharge test, for example, it is therefore terminal board take a measurement with the VoltageAnalyzer directly at terminal board .

The armature booster

An additional armature booster is armature booster for the MTC2 R7 testing device for testing anchors. This is required for testing larger, low-inductance DC anchors. The armature booster the surge current by a factor of 10 in order to detect short circuits and insulation faults between the laminations.

The armature booster connected to the test leads of the MTC2 R7. operator solid test probes are available to the operator at output booster. In addition, an integrated warning light indicates whether the terminals are voltage-free. An acoustic signal indicates whether the testGO GO n.GO .
