Experiment for learning fields

Experiment for learning fields 1, 7 and 9

Repair electrical machines and three-phase asynchronous fault simulator:

Learn how to design and how motors work
select suitable measuring devices
Detect engine error
be able to estimate repair possibilities

This will show the following error types of the three-phase asynchronous fault simulator:

winding closure
turn conclusion
Insulation error
Body closure

The different types of errors can be set via the switches A and B. In both cases, measurements have to be carried out by using digital multimeter and insulation measuring devices.

Experiment for learning field 2, 3, and 6 to 13

Building services systems and building system technology with LCN:

The erfi training center electrical installation contains all important installation circuits. There are dry, damp and fire-prone areas. In addition, the following topics are treated in detail and completely covered:

Protection types
Types of installation
Cables
Distributor
Counter
Ringer and intercom
Antenna system
Planning of plants
Commissioning and test report
Equipotential bonding

Overall experiment

Overall experiment building system technology with LCN

The conventional installation devices such as switches, buttons, sensors, etc. are replaced by small computer modules. These modules scan buttons, switch and dim lights, control blinds, control the heating, monitor the building, and so on. All computer modules in the building are interconnected. So each module can communicate information and commands to each other. A network of modules such as this, is call an installation bus.

LCN (Local Control Network) is a modern installation bus system for residential and commercial buildings. It takes over the functions of conventional electrical installation and perfects it:

The buildings are better and more comfortable controllable
Thanks to its own intelligence, LCN saves energy in lighting and heating
The buildings are easier to monitor via panels and visualization

Experiment for learning field 5

Device test fault simulators for device testing according to VDE 0701/0702:

In addition to the fields of application, the experiment will include and explain technical terms such as protection classes, actual and target states, testing, etc. Likewise, the most important test criteria such as protective conductor tests, insulation resistance measurements, equivalent leakage current measurements will be taught practically. The handling of appropriate measuring equipment is taught as well as a functional test and the labeling.

Learning goals:

Repair of electrical equipment
Change of electrical appliances
Testing electrical equipment

Test types:

Protective conductor resistance
Insulation resistance
Substitute leakage current
differential current
mains voltage
Consumer electricity
