GE Hydran 201Ti Continuous Dissolved Gas-in-Oil Transmitter

The GE Hydran H201Ti represents the fourth generation of compact, valve-mounted asset protection hardware developed to comply with standard IEEE C57.104 early warning frameworks. Positioned as an essential monitoring solution for small to medium-sized transmission and distribution transformers, the unit targets the root causes of insulation degradation before they escalate into high-consequence failure events.

The core detection engine relies on an advanced fuel cell sensor positioned directly behind a gas-permeable, vacuum-resistant membrane. This configuration yields a composite "Hydran Gas Value" in ppm, reflecting a 100% relative sensitivity to Hydrogen (H2) while maintaining targeted sensitivity to Carbon Monoxide (CO from degrading structural paper), Acetylene (C2H2 indicating active arcing), and Ethylene C2H4 indicating severe oil overheating). Utilizing passive Dynamic Oil Sampling driven by natural transformer convection currents, the transmitter continuously refreshes its sampling face without mechanical moving components.

• Pump-Free Fluid Interactions: Utilizes natural convective oil flow across the internal sampling manifold to remove mechanical failure points like pumps, rotors, and external piping.

• Dual Trend Tracking: Tripping mechanisms are independent, allowing operators to trigger early alerts based on standard gas thresholds or sharp hourly and daily gas generation surges.

• Multi-Node Networking: Built-in RS-485 line isolation supports daisy-chain network looping of up to 32 individual 201Ti transmitters or auxiliary controllers across distances up to 4,000 feet.

• Controller Compatibility: Integrates seamlessly with remote mounting modules like the H201Ci-1 (single-channel display clone) or the H201Ci-C (four-channel data concentrator for single-phase bank setups).

• Comprehensive Maintenance Diagnostics: Features automatic execution of an internal self-diagnostic routine every 15 days, immediately engaging a dedicated service alarm in the event of sensor drift, heating failure, or supply interruption.

• Substation Asset Management: Deploying low-maintenance monitoring fleets across non-critical transmission nodes to rank asset replacement strategies.

• Industrial Facility Subpanels: Protecting high-value rectifiers and furnace transformers inside heavy manufacturing plants from unexpected process interruptions.

• Fleet Screening Diagnostics: Serving as an alternative to periodic manual syringe fluid extractions by providing constant live telemetry.

• Ester-Based Fluid Deployments: Suitable for modern synthetic and natural ester-insulated transformers as well as standard mineral oils.

Q: What exactly does the composite gas reading represent on the display?

A: The composite reading is the cumulative total value of key fault gases dissolved in the oil.It responds fully (100%) to Hydrogen, but also scales and reflects the presence of Carbon Monoxide, Acetylene, and Ethylene based on their respective relative sensitivities.

Q: Can the H201Ti be mounted in cold ambient environments?

A: Yes. The device features an integrated internal heating plate assembly and is certified to operate reliably in ambient temperatures down to -40°C (-40°F).

Q: How does the H201Ti differ from the larger Hydran M2 system?

A: The H201Ti is an essential, single-gas transmitter focused strictly on composite fault-gas profiling.The Hydran M2 is a multi-parameter hub that adds discrete relative humidity (moisture in oil) tracking and onboard mathematical transformer modeling.

Q: Is on-site calibration or chemical gas standard injection required?

A: No field calibration is needed. The internal fuel cell architecture and factory certification isolate the device from baseline drift under normal operation, requiring only a mechanical sensor swap every 5 to 7 years depending on site conditions.
