Phase control fault simulator

The experiments are carried out on training panels in panel frames.

Objectives

• 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 (P_max. = 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:

• Breaks
• Short-circuits
• Wrong components
• Component faults

The faults are activated by slider switches located behind a lockable cover.

Highlights:

• Fault simulator phase angle is listed as a training board system.
• Minimised wiring effort, as the circuits only need to be supplemented by the measuring connections and some bridge connectors.

All functions of the Power Analyser CASSY can be operated quickly and directly via the display, the rotary wheel and the buttons on the unit. All settings and measurement results can be saved on the unit and quickly called up again later or simply downloaded.

In addition, the Power Analyser CASSY is fully controllable in real time via RJ45 Ethernet, W-LAN and USB-C interfaces.

These interfaces can be used by the following software:

• CASSY Lab 2 for drives and energy systems,
• MATLAB® and LabVIEW ™
• Lab Docs Editor Advanced

The following integrated servers are available in the Power Analyser CASSY for the local media connection of at least four end devices simultaneously.

For more details, see product data 727110 or 727111 Power Analyser CASSY.

The equipment is equally suitable for pupil and student experiments in the laboratory with low voltage (DC, AC and three-phase current) and - with a mobile trainer - for teacher demonstrations in the classroom or lecture hall. The experiments are carried out according to the manual.

The target group is made up of commercial apprentices and students of electrical machine construction. The course offers experiments at an intermediate level and also allows for the necessary insight into machine behaviour for scientific interpretation at undergraduate level. The media connection makes the experiments suitable for demonstration in the classroom or a lecture hall.

Topics

• 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)
