VaultSafe Transformer Monitor

Network transformers are located in underground vaults in cities throughout the world. Catastrophic failure of a network transformer can cause serious harm to the public. The VaultSafe Transformer Monitor is a low cost solution that uses a single hydrogen sensor to sample the headspace in all three compartments of a network transformer. Consequently, it serves as an early warning sign of incipient faults developing in network transformers.

VaultSafe uses one sensor to monitor all three compartments

One Sensor Monitors All Three Compartments

There are three compartments on a vault transformer: main tank, switch, and cable compartments. Conventional monitors only look at hydrogen in the main tank even though failure is most likely to occur in the cable compartment. The VaultSafe Transformer Monitor uses one sensor to continuously monitor all three compartments so that you are aware when hydrogen in the transformer headspace has increased.

Maintenance Free Monitoring of Hydrogen Gas and Pressure

The VaultSafe monitors hydrogen gas and pressure in all transformer compartments which provides early detection of problems and greatly reduces the potential for failure. Pressure is monitored across all three compartments which prevents moisture or atmosphere ingress. The VaultSafe monitor is submersible, maintenance free and self-calibrating.

Easy to Install

The VaultSafe Transformer Monitor can be installed in less than 45 minutes. Don’t believe us? Check out our video.
