PowerVault.
What's underground shouldn't be invisible.
Underground transformer vaults present unique challenges — no line-of-sight, confined spaces, toxic atmospheres, and no practical path for routine inspection. PowerVault is the first purpose-built continuous monitoring system for underground transformer vaults, delivering the same thermal intelligence as above-ground substations to the infrastructure that powers urban cores.
Underground vaults are the blind spots of urban power grids
Confined space entry hazards
Transformer vaults contain toxic gases, explosive atmospheres, and extreme heat. Manual inspection exposes workers to serious danger — and is often legally restricted without extensive safety protocols.
Inspection is infrequent — faults aren't
Urban transformer vaults might be physically inspected quarterly at best. But fault conditions develop continuously. Between inspections, there's no visibility.
Failure causes catastrophic urban disruption
A failed underground transformer in a dense urban core can mean days of power disruption, street-level fires, and millions in economic losses — with no quick replacement path.
PowerVault: continuous monitoring, zero entry
Permanently-installed sensors deliver 24/7 thermal, gas, and moisture data from inside the vault — without anyone ever needing to go in for routine monitoring.
Persistent visibility into every vault, everywhere
Thermal monitoring at distance
Far-field infrared imaging of transformer bodies through vault access points — no direct contact required.
Dissolved gas analysis (DGA)
Real-time oil gas monitoring detects internal transformer faults before thermal signatures appear.
Water intrusion detection
Vault flooding is a leading cause of underground transformer failure. Moisture sensors alert before water reaches critical levels.
Multi-path communications
Underground environments challenge radio communications. PowerVault uses multiple comms paths to ensure data always reaches your team.
Stop flying blind underground
PowerVault brings the same continuous monitoring intelligence your above-ground assets have to every vault, manhole, and underground substation in your network.
