Narrative

Technical Innovation & Quality Heritage

YTL’s Three Phase Smart Meters are heavy-duty energy management tools designed for industrial, commercial, and high-load residential applications. As energy systems grow more complex, the ability to monitor balanced and unbalanced three-phase loads with high precision becomes vital. Our meters offer 4-quadrant measurement, capturing active and reactive energy in both directions, which is essential for facilities with large inductive motors or solar PV arrays. As a leading manufacturer, Zhejiang Yongtailong builds these meters with high-surge protection and harmonic analysis capabilities. By providing comprehensive power quality data—including voltage sags, swells, and frequency fluctuations—our three-phase solutions allow facility managers to protect expensive industrial assets while maintaining strict control over their enterprise-wide energy costs.

Product Application

  • Manufacturing Facilities
  • Commercial Office Towers
  • Renewable Energy Hubs

Manufacturing Facilities

Specifically designed to handle the high-current demands and electrical noise of industrial shop floors. These meters monitor the performance of heavy machinery, helping plant managers identify phase imbalances that could lead to motor overheating and costly downtime.

Commercial Office Towers

Ideal for managing the complex energy distribution of large skyscrapers. By monitoring the main feed and sub-distribution panels, building owners can accurately allocate energy costs to different commercial tenants based on their actual consumption patterns.

Renewable Energy Hubs

Critical for large-scale solar farms or wind energy sites. These meters measure bidirectional energy flow with 4-quadrant precision, ensuring that the utility company accurately records both the energy produced and the energy consumed by the facility.

Product Advantages

Phase Loss Protection

Automatically detects and logs the loss of any single phase, triggering an immediate alert to prevent damage to expensive three-phase motors and sensitive electronics.

Advanced Power Quality

Includes built-in harmonic distortion analysis and voltage event logging, giving engineers the data needed to diagnose "dirty" power issues before they cause failures.

Scalable Connectivity

Integrated with high-speed RS485 and optional wireless modules (GPRS/NB-IoT), making it easy to sync data with building automation and SCADA systems.

Frequently Asked Questions

  • Q: Can I use this for both 3-wire and 4-wire systems?

    A: We offer dedicated models for both 3P3W and 3P4W. Please ensure you specify your system type to ensure the internal power supply matches your local grid.

  • Q: How many time slots can I set for peak/off-peak billing?

    A: Our three-phase meters support up to 12 daily time segments and 8 different tariffs, allowing for very complex Time-of-Use (TOU) billing schedules.

  • Q: Is the meter capable of measuring harmonics?

    A: Yes, our high-end models measure Total Harmonic Distortion (THD) and individual harmonics up to the 31st order for both voltage and current.

  • Q: Do you offer a CT-operated version for very high currents?

    A: Yes, we provide 1.5(6)A CT-operated meters that can work with any standard external current transformer to monitor loads exceeding 1000A.

  • Q: Does it have a pulse output for my energy logger?

    A: Every meter comes with at least one passive pulse output (S0 interface) which is compatible with most third-party data loggers and PLC systems.
