Features
Ensure the safety, reliability, and continuity of your network transformer fleet with HY-VAULT. H2scan’s HY-VAULT solution measures hydrogen generation, a leading indicator of an impending failure in network transformers. That knowledge allows grid operators to reduce unplanned outages, protect personnel and formulate maintenance plans that keep power flowing to businesses, homes, and critical infrastructure.

High-temperature engineering for continuous operation at 125°C (257°F)
IP68 Ingress Protection hydrogen measurement
Long operating life expectancy
2-Wire RS485, Modbus RTU, DNP3 serial communication
No periodic maintenance is required thanks to the patented self-calibration
