Definium’s Power Guardian is a drop-in safety solution for monitoring neutral current leakage, with alerts, in communications cabinets and other always-on assets which cannot utilise RCDs. Multiple back-haul network technologies and additional monitoring/metering options are available, making the Guardian one of the most flexible safety devices on the market.
The Power Guardian is based on Definium’s Internet of Things sensor platform, utilising a robust Ethernet connection to report metrics in near real-time. Optional communications redundancy is available via LTE Cat. M1/NB1 (eMTC/NB-IoT) or LoRaWAN, ensuring messages get through during localised network outages. An optional backup battery enables a “last gasp” transmission during power outages.
The Power Guardian constantly measures power usage, reporting neutral/earth current leakage and other potentially dangerous situations within seconds.
Energy metering is optionally available and provides sub-metering capability and numerous other power quality metric reporting.
Optional environmental monitoring of air temperature and relative humidity, along with a differential pressure sensor for monitoring filter cleanliness, enables condition-based maintenance for the enclosing cabinet. An optional accelerometer reports impacts to the enclosure.
The Guardian is powered directly via the monitored source and only requires active and neutral connections, plus networking.
Each Guardian comes pre-configured with unique internal ids and encryption keys, reducing overall commissioning time. Settings can be altered remotely via each of the network communications methods.
Definium Technologies designs and manufactures its devices in-house in Launceston, Tasmania. Definium produces a broad range of gateways and sensors to use in any IoT network.
