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:
1. winding closure
2. turn conclusion
3. Insulation error
4. 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.

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 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
