Trumeter Guardian Monitoring System is a power and protective conductor monitoring solution for detecting and protecting against broken neutral faults and stray voltages on connected services. This device continuously monitors the electricity supply and the electrical infrastructure of the building and can isolate or warn of any detected faults. The faults include loss of neutral, broken pen conductors, voltage on protective earth/ground conductors, high and low line voltages, and high and low frequencies. The Guardian monitoring system is connected to the main incoming supply and at each distribution board of the infrastructure. This device can also connect to a cloud-based portal, allowing users to view the devices at any time.
