Ensure maximum electrical safety and prevent equipment damage with this advanced line-tracking module. It provides clear, immediate feedback on circuit integrity and potential faults, keeping operators informed and high-voltage manufacturing systems running securely.
Ensure maximum electrical safety and prevent equipment damage with this advanced line-tracking module. It provides clear, immediate feedback on circuit integrity and potential faults, keeping operators informed and high-voltage manufacturing systems running securely.
The Guardian is an advanced power and protective conductor monitoring system, designed to detect and safeguard electrical systems against broken neutral faults and stray voltages on connected services. It continuously monitors the electricity supply and electrical infrastructure, with the capability to isolate or alert any detected faults, including loss of neutral, broken PEN conductors, voltage on protective earth/ground conductors, high and low line voltages and frequencies.
Incorporating patented O-PEN® technology from matt:e, a leading expert in broken neutral and PEN fault protection products, the Guardian provides comprehensive protection to assets and people, including cloud-based real-time monitoring with matt:e cloud, with SMS and email alerts for potential failures.
The Guardian is easily installed in or alongside any existing distribution board with a three-phase supply. For complete protection, it should be connected to the main incoming supply and at each distribution board within the infrastructure, providing essential protection against conditions typically undetected by standard building circuit breakers, RCDs, MCBs, or surge protection devices.
