Contactless Temperature Sensing
Transformer Health Monitor is based on Multi Nano Sense Technologies Private Limited’s patented Solid State Electrochemical Sensor Technology with Solid Electrolyte and Novel Reference Electrode. It directly measures partial pressure of Hydrogen, by diffusion, in a gas mixture making it specific, selective, and intelligent to Hydrogen alone. This analyser can work in multiple gas backgrounds including Air, Inert and Combustible Gases. This sensor can be deployed to analyse the concentration and rate of outgassing of Hydrogen from the transformer oil in case of occurrence of any incipient fault. All kinds of transformer faults cause chemical changes in the oil, which generates differing levels of Hydrogen, based on the nature of fault. Almost ~92% of the Hydrogen is not soluble in oil and can be analyzed in Gas Phase through strategic placement of a Hydrogen analyzer. This is a simple and affordable solution for first line of defense against violent transformer explosions and early diagnosis of faults for remedial action at initial damage stage. The sensor design is as per intrinsic safety method of protection (not capable of causing a spark which can cause an explosion in hazardous area) and uses a powder coated Aluminium enclosure, weighing less than 350 grams, 4-5X lighter and smaller than commercially available sensors for hazardous area installations.
Solution Features
- This is a very low-cost alternative to online DGA systems.
- Unique capabilities make gas phase Hydrogen measurement possible, for real time analysis:
- Enables fleet wide monitoring of all transformers on an aggregated at granular level.
- Classifies transformers into levels of health criticality and prompts immediate shutdown in case a transformer starts moving towards violent and catastrophic failure.
- Simple engineering adds to affordability and ease of deployment – very low-down time.
- Does not require manual sampling or complex systems for extracting the gas from oil.
- The design offers flexibility to adapt to transformer type and construction.
- <Name of Product> can be deployed using suitably designed adapters to engage at the Buchholz Relay, Conservator Tank or Breather Vent.
- Wired communication for interface with existing SCADA, PLC or other data gathering system through Industry standard RS 485 communication protocol.
- Wireless communication options like GSM, LoRa, Wi-Fi and RF for interfacing with the cloud platform.
- Supported by a powerful analytics platform with rule-based condition monitoring, information visualization, data historian, email alerts and report generation capabilities.
- Progressively upon deployment, the analytics platform shall grow and become intelligent. It can learn patterns and recognize anomalous behavior, ultimately leading to pattern based fault prediction. The learning engine can be coached decades of engineering and utility operational intelligence in sync with your organizational knowledge, to build a robust watchdog and predictive system, to monitor the full fleet with reliability and assurance.
- Modular capability for additional sensing requirements.
