1. Demo Unit:

– SAS has developed a demo unit that can wirelessly scan and detect the temperature of a sensor located up to 60 feet away from the interrogator or scanner unit.

– The interrogator is a special wireless transmitter and receiver device (RADAR) that uses sophisticated frequency scanning methods to sweep over the entire range of radio frequencies in the 2.4 GHz ISM band (the same wireless frequency band used by Wi-Fi and Bluetooth consumer devices) to probe for a response signal from SAS wireless temperature sensors mounted on the transmission lines.

– When the sensors are stimulated by the interrogator it responds at a specific characteristic frequency (unique to each sensor). The Interrogator calculates the sensor temperature from the observed frequency. Temperature range can be from -60 to +250C. From the temperature of the power lines and the ambient temperature, it is possible to calculate the Dynamic Thermal Circuit Rating (DTCR) of the power lines, the sag in the power lines, and the resulting ampacity of the power lines – a measure of the maximum amount of electric current which can be safely transmitted down the high voltage power lines.

– The unit is available for demonstration to customers, potential investors, the financial community and other interested parties.

2. Letter of Collaboration:

– SAS has received a collaboration letter from Tri State Generation and Transmission Association Inc. Colorado, to Install and test the system.

– Tri State Generation and Transmission Association Inc. Colorado is a power utility company with its headquarters in Denver Colorado and comprises of several utility companies in the three states of WY, NM, and CO in USA.

– SAS is planning to have a system ready for installation by Tri State by end of 2014.

3. Back Haul Software development:

– One of the requirements of the DTCR system is to securely transmit the real time data from the Interrogator to asset managers and control centres of the power utility companies.

– Work is underway to develop the integration of the SAS wireless DTCR interrogator unit with “backhaul” cellular networks to publish or distribute temperature and DTCR sensor data to file servers on a client network. We will be able to monitor and plot real-time temperature changes as a time series at the customer control centre. A suite of backhaul connection methods, such as SCADA, will ultimately be required to integrate into customer networks.

– We are developing the software that detects the temperature of multiple sensors.
