Narrative

Technical Innovation & Quality Heritage

YTL’s Anti-Tamper Split Meters provide a dual-layered defense against electricity theft by separating the core metering unit from the user's view. As a leading manufacturer in revenue protection, Zhejiang Yongtailong designed this system with a pole-mounted MCU (Measurement Control Unit) and an indoor CIU (User Interface Unit). This physical separation makes illegal bypassing and physical tampering nearly impossible for the consumer. The MCU features advanced sensors to detect magnetic fields, neutral missing scenarios, and cabinet intrusion. Communication between units via PLC or RF ensures the user can still manage their credit and monitor usage while the utility maintains absolute control over the high-voltage metrology hardware in a secure, inaccessible location.

  • Public Lighting Power Monitoring

Revenue Protection in High-Loss Areas

In regions where energy theft is a systemic issue, standard meters are often bypassed or physically damaged to under-record consumption. Our Anti-Tamper Split Meters solve this by removing the meter from the user's reach. By mounting the MCU unit high on a utility pole, the opportunity for a consumer to earth the neutral or bypass the phase is eliminated. The utility can accurately recover 100% of the energy costs while providing the consumer with a convenient indoor CIU to check their balance, creating a transparent yet highly secure "pay-as-you-go" energy ecosystem.

Social Housing Utility Security

Perfect for government housing projects where ensuring utility payment is critical for operational sustainability. The split design prevents tenants from intentionally damaging the meter to avoid payment. Since the billing logic and relay reside in the secure MCU unit, the power can be automatically disconnected for zero credit or tamper attempts, even if the indoor CIU is destroyed. This ensures that the housing authority maintains a steady revenue stream and can provide energy services to low-income families without the risk of accumulating massive tenant debts.

Public Lighting Power Monitoring

Used to monitor and protect the power supply of street lighting and public infrastructure. By using split meters, the metrology units can be locked inside a reinforced central distribution pillar, while the display interface is available for maintenance staff. This prevents illegal tapping of the public grid by street vendors or unauthorized third parties. The system provides immediate alerts to the municipal office if a bypass is detected, ensuring that taxpayer-funded electricity is only used for its intended public safety purposes.

Product Advantages

Unreachable Metrology Unit

By installing the core billing hardware in an elevated or locked enclosure, you physically eliminate the consumer's ability to manipulate or bypass the measurement sensors.

Dual-Line Current Sensing

Monitors both the live and neutral wires for discrepancies; if a current imbalance is detected (indicating a bypass), the meter automatically logs a tamper event and can trip the relay.

Encrypted Link to CIU

The communication between the outdoor MCU and indoor CIU is highly encrypted, preventing any "man-in-the-middle" attacks that attempt to forge credit or usage data.

Frequently Asked Questions

  • Q: Can the meter be bypassed at the pole?

    A: Our MCU units are designed for installation in specialized, anti-climb pole boxes that make unauthorized access nearly impossible and highly visible.

  • Q: How does the utility know if the cabinet is opened?

    A: The MCU features a micro-switch that triggers an immediate "Intrusion Alarm" sent to the central AMI system the moment the enclosure cover is moved.

  • Q: What if the consumer earthing the neutral?

    A: The meter’s dual-measurement technology detects if the return current is missing and will continue to bill based on the phase current, preventing the "earth-neutral" theft method.

  • Q: Can one CIU be used for another MCU?

    A: No, each CIU is securely paired with its specific MCU using a unique encryption key, ensuring that users cannot swap units to steal credit.

  • Q: Is the system weatherproof?

    A: Yes, the outdoor MCU unit is rated IP67 or IP54 with a robust, UV-stabilized casing, designed to survive over 15 years in harsh tropical or desert environments.
