3-Phase Fault Simulation and Training System

The 3-Phase Fault Simulation and Training System is an advanced educational tool designed specifically for training apprentices, trainees, and students in the electrical industry. Its purpose is to provide hands-on experience with fault scenarios, promoting a deeper understanding of electrical systems and fault analysis. The system is intended for installation in colleges and training centres offering electrical training programs.

System Features and Setup

• Input and Output Capabilities:

  • Operates with a 24V or 240v input, capable of generating:

    • ELV (Extra Low Voltage) 24V single-phase at 100VA.

    • ELV 41.5V three-phase at 100VA.

    • LV (Low Voltage) 240V single-phase and 415V three-phase at 1KVA.

• Control and Configuration:

  • Features a touch-screen interface for intuitive operation.

  • Fully computer-controlled to ensure faults cannot overlap or interact in unintended ways, maintaining system stability.

Simulated Fault Types and Scenarios

The system offers comprehensive fault simulations, including but not limited to:

• Phase-to-phase faults.

• Phase-to-ground faults.

• Earthing system faults.

• Phase and neutral swaps.

• High-voltage transformer faults which affect low-voltage systems.

• Symmetrical and unsymmetrical faults.

Operation and Analysis

• Supports dynamic fault testing and pre-configured fault scenarios, adaptable for various training needs.

• Compatible with standard test equipment, enabling real-time monitoring and analysis of fault conditions.

Safety Features and Protections

Safety is paramount in the system’s design, incorporating the following features:

• Electrical Isolation:

  • Uses an isolation transformer to separate the system from the main earthing grid, preventing earth potential rise or differences.

• Overcurrent and RCD Protection:

  • The circuits are protected during normal operations, with RCD bypass enabled for specific fault simulations (clearly indicated via on-screen warnings).

• Compliance with Standards:

  • Equipped with AS3000-approved protection devices for both ELV and LV modes.

Educational Benefits

This system is a standalone training solution that adheres to Australian Standards (AS/NZS 3000: Electrical Installations), ensuring safety, reliability, and relevance for the local industry.

Target Audience

The system is designed to benefit a range of users, including:

• Electrical apprentices and trainees.

• Engineering students specialising in power systems.

• Professionals seeking advanced fault analysis training.

This cutting-edge simulation system bridges the gap between theoretical learning and practical application, preparing the next generation of electrical professionals with a solid foundation in fault identification, safety, and system management.
