Micromem Technologies Inc. Provides Update on MEMS-based Sensor Solution to Detect Transformer Partial DischargeNovember 13, 2014
TORONTO and NEW YORK -- Micromem Technologies Inc. announces further to the Joint Development Agreement (JDA) announced December 11, 2013 with its American based Utilities Company Client, the Company successfully demonstrated Stage Gate Two of the Transformer Partial Discharge Proof of Concept (POC) and an invoice for $200,000 USD was issued to the Client as an initial payment towards the Contract. On October 30, 2014, a live demonstration of the POC MEMS-based Sensor Solution to detect transformer partial discharge was successfully demonstrated on the Client's targeted transformer following a client approved protocol. The criteria to measure success were as follows:
• Demonstrate optical array acoustic, real-time detecton of partial discharges
• Demonstrate the ability to localize partial discharges
• Demonstrate the ability to assign a severity to the detected partial discharges
• Provide a visualization of partial discharges location
• Provide mobile reporting of alarms and events
• Provide the ability to store a history of time-stamped partial discharges by location and transformer
• All criteria were demonstrated successfully
This is the first technology of its kind that is able to measure the nanosecond partial discharge events with sensors installed in the oil of a transformer. Current competitive technology attempts to detect and localize partial discharges with devices installed on the metal housing of the transformer. Our approach is more effective due to the radical difference in the speed of sound in oil and in steel.
MAST patented sensors are located in the critical areas of a transformer, directly in the oil and are designed to detect the partial discharge event, measure the severity of the partial discharge and locate it accurately so as to inform the user of the root cause of the partial discharge and how to direct their maintenance effort.
Furthermore, the architecture provides commercialization pathways (Stage Gate Three) for integrated transformer health monitoring and monitoring of partial discharges in aging transformers.
Both Micromem and this Client are now working through the logistics of an order for this technology for deployment within their network.
