WT-FY24B Mobile Energy Metering & Electrician Practical Skills System (Case-type)
The system utilizes DC power supply below safety voltage levels. The output voltage and current employ low-signal AC to simulate real-world voltage/current amplitudes and power factors. This mobile simulation System can replicate various wiring configurations for 3-phase 3-wire (3P3W) and 3-phase 4-wire (3P4W) energy meters. Despite its compact size, it offers rich functionality, simulating tens of millions of wiring combinations. It is ideal for professional skill training and assessment for personnel in energy metering and power inspection at vocational schools, training centers, and utility departments.
Core Positioning: A medium-sized training system that balances “mobile portability” with “dual-meter collaborative training.” Featuring an aluminum alloy case with a trolley-and-wheel design, it is specifically built for small-to-medium training centers, skill competitions, and certification scenarios.
