  • HV 3P3W via VT (Y/Y connection) and CT (simplified wiring).
  • HV 3P3W via VT (Y/Y connection) and CT (phase-separated wiring).
  • HV 3P4W via VT (Y0/Y0 connection) and CT (simplified wiring).
  • HV 3P4W via VT (Y0/Y0 connection) and CT (phase-separated wiring).
  • LV 3P4W (no VT) via CT (simplified wiring).
  • LV 3P4W (no VT) via CT (phase-separated wiring).
  • LV 3P4W direct connection.
• Voltage Neutral Miswiring Simulation: Simulates incorrect sequence wiring between the voltage neutral and phase lines.
• Current Common-Wire Miswiring Simulation: For simplified current wiring, simulates incorrect sequence wiring between the common wire and phase lines.
• Secondary Circuit Fault Simulation: VT secondary phase loss, VT secondary reverse connection, CT secondary polarity reversal, incorrect meter terminal entry/exit, CT secondary short circuit, and CT secondary open circuit.
• VT/CT Secondary Grounding: Simulates grounded vs. ungrounded secondary circuits.
• CT Series Wiring Fault: Simulates series wiring faults when CT secondary phase-separated currents are ungrounded.
• Analysis Tools: Supports wiring diagram plotting and Energy Retroactive Compensation calculations.
• Control Signal Testing: Wiring and testing of weak-current signals like Remote Control (RC) and Remote Signaling (RS) for Load Control Terminals.
• Fault Simulation: Simulates typical meter/terminal faults such as parameter errors, display anomalies, terminal crashes, data errors, and communication failures.
• Timed Assessment: Features a voice-prompted countdown timer (up to 99:59) with pause/resume and a 5-minute remaining warning.
• Question Bank Management: Allows free combination of wiring elements to create or delete exam questions; supports simulation of any question in the bank.
• Secondary Circuit Protection & Alarms:
  • Independent Operation: Fault alarms at one station do not affect the other during parallel operation.

Product Features

• Parallel Dual-Station Design: Industrial cabinet with two independent stations allowing students to practice different scenarios simultaneously via a centralized touch-control PC.
• Full Parameter Coverage: Program-controlled voltage and current output to perfectly replicate all metering conditions (HV, LV, 3P3W, 3P4W, transformer-rated, or direct-connect).
• Multi-Layer Safety: Built-in voltage overcurrent protection, CT open-circuit alarms, short-circuit protection, and safety power sockets. Automatically identifies misoperations to cut off dangerous signals.
• Diverse Metering Combinations: Supports “Primary + Secondary Meter” or “Meter + Load Control Terminal” setups. Simulates 24 complex fault combinations, including neutral/common wire miswiring and CT series circuit faults.
• Remote Network Control: A single PC can manage multiple units for unified fault settings and scoring, ideal for large-scale skill competitions with “zero manual intervention.”
