Automated Transformer Radiator Isolation System

A transformer monitoring device that responds to radiator damage by: timestamping the incident via nitrogen high-flow activation, triggering local alarm systems with horn and flashing light as deterrents, remotely alerting dispatch, monitoring oil levels, and automatically isolating the transformer while closing radiator valves to preserve tank integrity.

Transformer oil spill incident - the problem ATRIS solves
The Challenge

Substation Physical Security

Substation Physical Security has limited options today. Walls are expensive and don't protect from drone attacks or stations in low lying areas. ATRIS will mitigate oil leaks near critical waterways/habitats, reducing environmental liability. Quick recovery by isolating single radiator section damage, derating transformer, running fans in manual, return to operation. Save the rich history that exists in the oil for future oil analysis. Prevent costly oil clean up. Integrate the isolation of one damaged transformer into station automation to transfer low side bus to unaffected transformer.

Why ATRIS

Benefits of ATRIS

This system automatically isolates leaking transformer radiators, preventing oil loss, avoiding environmental spills, and protecting the transformer—using the valves you already have.

Rapid Recovery

Quick recovery by isolating single radiator section damage, derating transformer, running fans in manual, return to operation.

Environmental Protection

Mitigate oil leaks near critical waterways/habitats, reducing environmental liability. Prevent costly oil clean up.

Oil Analysis Preservation

Save the rich history that exists in the oil for future oil analysis. Maintain diagnostic capabilities.

Station Automation Integration

Integrate the isolation of one damaged transformer into station automation to transfer low side bus to unaffected transformer.

Capabilities

Features in Xfrmr Monitor

Comprehensive monitoring and control capabilities designed for utility-grade reliability and integration.

  • Time stamps for authorities
  • Easy programming for up to 7 radiator sections per monitor
  • Remote control capabilities to isolate single valves (with station cameras)
  • Sequential valve operation to limit battery loading
  • Limits employee exposure to situation by automating the closing of the valves
  • Optional N2 tank and blanket pressure analog remote monitoring
  • Non-invasive and easily transferrable at EOL of transformer
  • Options to transfer logic into station RTU or other monitoring equipment
  • Cybersecurity embedded into physical wiring to prevent outsiders from closing valves

Hardware

Valve Motor Actuator

Noninvasive DC actuator

  • 24-240 VDC actuator mounts to existing isolation valves by extending existing bolts and adding mounting bracket
  • New mounting bracket offers multiple adjustment for ease of alignment
  • Torque limiter integrated in actuator
  • Close and Open limit switches integrated in actuator to identify "all open" or "all closed"
  • Manual/Auto switch to allow operator to manually open and close valve without removal

Installation process with C-clamps
Installation

Installation Process

Using two 'C' clamps, you can remove one bolt at a time and replace it with a longer bolt. This is done twice for both bottom bolts. Then the bracket can be easily added to these longer bolts. Using slotted connections on a two-piece bracket, the actuator shaft can be easily aligned with the valve stem. Additional instructions are provided at the time of purchase.

Investment

Cost Discussion

One time license fee for small utilities under 50,000 meters and larger utilities exceeding that threshold. Both licenses cover existing and future installations. Transformer material costs are similar to costs for high end camera purchase prices.
