Best In class Ground Monitor for modernisation of low voltage grids
The Scavenger™ Ground Mount provides highly granular power quality monitoring on all types of ground mounted distribution transformers including pad-mounted, unit-substation and wind farm transformers. The device measures to Class S power quality and its capability of recording the waveform at 32khZ on the incoming feed and 6 secondary feeders. With a total of 28 individual current measurements, the Scavenger™ Ground Mount is unrivalled in its measurement capability.
Designed in collaboration with transformer manufacturers to monitor asset health and capacity throughout the life of the asset, Scavenger™ Ground Mount delivers a new standard in LV asset management. This enables proactive protection, reinforcement and maintenance of vital grid assets through continuous remote monitoring.
Visualise the front line of the grid with Scavenger’s Class S PQ monitoring capabilities:
- Voltage visibility in real time – Identify fluctuations and reverse power conditions immediately
- Capacity planning: profiling and modelling across your fleet using the VT Electron Cloud™ platform
- Transformer diagnostics and health rating supporting asset re-rating and uprating decision data
- Improved asset life-cycle management and reduced maintenance
- Decision based data for reinforcement/ deferral ROI
- Understand where congestion is and avoid overloading – ensuring a reliable and secure supply
- Model the impact of low carbon technologies on the grid asset and plan reinforcement years in advance
- Detect faults immediately with our events reporting module – faster response times and less downtime
- Get more out of existing assets through VT Electron’s load re-rating
- Avoid faults – VT’s 32khz waveform sensing and pre-fault machine learning models predict faults in advance
- Manage micro-generation and DERMS better with visibility over the last mile of the grid
- Monitor the Total Harmonic Distortion (THD) and better protect vital grid assets
- For the most critical assets add temperature monitoring and remote dissolved gas analysis for additional asset health insights.
The frontier of LV Monitoring
With no gateways or repeaters the Scavenger™ Ground Mount is a self contained unit which utilises public or private LTE to deliver real time girds monitoring at scale and on budget. We utilise advanced IoT and meteorology processors to deliver unrivalled real-time visibility on transformer performance, capacity and faults.
Large scale roll out is supported by VT’s installation app (iPhone & Android) which records feeder names, GPS location and asset details to provide project managers with all the data required to manage the roll out of Scavenger™ at scale.
