Zillion VTN
Earth leakage supervisor
The VTN Earth Leakage Supervisor is an advanced monitoring device that continuously measures the potential difference between the low-voltage neutral and protective earth in secondary substations. This parameter, which is not typically monitored, provides a key indicator of the electrical condition of the network.
An increase in neutral-to-earth voltage may indicate leakage currents, insulation deterioration, load imbalance or neutral degradation. By continuously monitoring this variable, the VTN Earth Leakage Supervisor acts as an early warning system, enabling abnormal conditions to be identified before they develop into faults, technical losses or safety risks.
Natively integrated into the Zillion ecosystem, the VTN Earth Leakage Supervisor adds an additional layer of visibility that complements conventional electrical monitoring, improving substation diagnostics and operational decision-making.
Value proposition of the VTN Earth Leakage Supervisor
Early anomaly detection. Continuous monitoring of neutral-to-earth voltage enables the identification of incipient leakage currents and small earth leakages before protection devices are triggered.
Visibility into technical losses. Provides key information to analyse electrical leakage, insulation degradation and non-apparent losses in low-voltage networks.
Integrated dedicated monitoring. Introduces a critical variable that complements conventional electrical monitoring, enhancing diagnostics of the secondary substation’s condition.
Improved safety. Enables the early detection of abnormal voltages on exposed conductive parts and hazardous conditions before they affect people or infrastructure.
Primary use case of the VTN Earth Leakage Supervisor
Continuous monitoring of neutral-to-earth voltage in secondary substations as an early indicator of leakage currents, technical losses and incipient neutral faults. The VTN Earth Leakage Supervisor enables proactive intervention before damage, power outages or electrical hazards occur, reducing fault location time and narrowing the issue down to the secondary substation.
