Interactive Lab Assistant: Protection for transformers

The experiment instructions come in the form of an Interactive Lab Assistant course. This multimedia course is a step-by-step guide through the topic of modern energy systems. The fundamentals are conveyed using easy to understand animations. The Interactive Lab Assistant in conjunction with the SCADA Viewer constitutes a comfortable experimenting environment.

Special features:

• Interactive experiment setups

• Measured values and diagrams can be stored in the experiment instructions per drag and drop

• The SCADA Viewer can be started directly from the experiment instructions

• Includes questions with feedback and evaluation logic for progress monitoring

• Documents can be printed out for hardcopy of experiment instructions including solutions

• Labsoft browser, course software and SCADA Viewer

Training contents:

• Detection and disconnection of transformer for internal faults

• Detection of peak inrush currents (RUSH) without disconnection

• Faulty tripping due to incorrectly sized transformers

• Selection of tripping characteristics with differential currents taken into account

• Setting the parameters of a time overcurrent relay taking the current transformation into consideration

• Detection of operating values for symmetrical and asymmetrical faults

• False tripping of the protective device during the transformer’s switch-on response

• Transformer switch-on response in terms of protection

• Course duration 9 h approx.
