In the national electrical grid, sagging power lines can be a major cause of outages across the country. Sagging power lines can cause a short behind the transformer due to changes in wind speed and direction. Working with a respected utility company client, MAST has developed the EAGLE (TM) power line sensor – a magnetic current monitor with power scavenging that includes acoustic sensors to measure line height and wind velocity, and an accelerometer for line motion to provide continuous real time measurements to the Operations Center and early detection of potential power line sag induced failures. The EAGLE (TM) line monitor also includes sensors to measure line current, voltage and temperature for operations.
Cement Integrity Sensor Solution
MAST is currently in trials with a major oil company to develop a remote monitoring system to assess the structural integrity of the cement that surrounds the steel casing of the bore hole in offshore wells. Recent events in the Gulf have increased the urgency to find a solution to this long-standing industry problem. Significant challenges from the extremely high pressures and temperatures of the down hole environment are being met with unique MEMS sensors and advanced packaging techniques.
Corrosion Detection Solution
MAST is working with a client in the oil industry on detecting corrosion on pipelines under the insulation. Currently, detecting and repairing corroded sections of a pipeline is a time consuming and expensive process. MAST has developed a system using a pervasive deployment of permanent wireless MEMS corrosion sensors attached to pipes under the insulation and communicating to base stations positioned along the pipeline. Sensor messages are routed to the client command center where they are monitored.
