The experiments are carried out on training panels in panel frames.
- Protective measures and electrical safety
- Finding and analysing faults in phase angle control circuits
- Use of commercial measuring instruments: hand-held multimeters and oscilloscopes
The fault simulator is a standard dimmer for a resistive load (Pmax. = 1.2 kW) pre-calibrated for minimum value. Various measuring points allow for systematic troubleshooting. There are a total of 20 faults which can be switched and which are of the following categories:
- Short circuits
- Wrong components
- Component faults
The faults are activated by slider switches located behind a lockable cover.
The equipment set is designed for student experiments in a laboratory using low voltage (230 V AC). Experiment procedures are provided in a printed manual.
The target group is students in vocational colleges. The experiments are intended as an introduction at a simple level.
- Investigation of a circuit with some 20 different faults
- Component faults (short circuits, high resistance)
- Breaks in conductors
- High or low-resistance connections within the circuit
- Wrong or missing components (e.g. incorrect values)
