FAQ

  1. What is SAS’s proprietary Technology?

    SAS utilizes its wireless technology to monitor stress/strain and temperature of transmission lines with the help of battery-less, wireless sensors and transmits the information to a control centre via its proprietary system. It computes the transmission line capacity of the power line in real time.

  2. What parameters does it measure?

    SAS DTCR system measures Stress/Strain, temperature of the conductor, environmental temperature, wind velocity, wind direction, and solar radiation. It can detect ice build-up on the conductor. From these measured parameters, it calculates the Line Capacity, Sag of the line, temperature of the central conductor, and estimates remaining life of the conductor (Info on Aging) allowing utility companies to increase line capacity and reliability as well as to make well supported decisions on conductor maintenance and replacement needs.

  3. What major hurdles do the Utility Companies face?

    Utility companies face three major hurdles:

    • Existing limitations in its organization.
    • Technical ability to meet 25 and 50-year electricity demand.
    • Capacity to increase efficiency minimizing transmission congestion without diminishing reliability and security of the electrical grid.
  4. What solution does SAS offer?

    SAS solutions offer real time monitoring of transmission lines allowing the utility companies to increase the capacity of transmission lines, improving reliability of the system thereby resulting in savings of millions of dollars for utility companies and rate players. This also allows it to estimate the aging and condition of the conductor.

  5. Who are the closest competitors?
    • Nexan CAT-1 system
    • PikeThermarate
    • EDM Sagometer
  6. What is the market size and what are the key sectors?

    The total North American transmission market alone is $16 billion. When you include the other verticals, it adds tens of billions to this number. The other verticals are:

    • Civil Infrastructure Market
    • Petroleum & Gas Pipeline Market
    • Civil Infrastructure
  7. Why Power lines?

    Even though our technology has applications in several different verticals, there is an immediate need to increase capacity in electrical transmission. At certain locations, transmission congestion is an issue that could be decreased and/or alleviated using DTCR technology. Our solution provides the utility Companies not only the tools to increase capacity but provides valuable information about condition and remaining life of the conductor thereby deferring expensive capital expenditures.

  8. What is Static line rating?

    When transmission lines are designed, the code specific clearance thresholds are used in combination with structural design information, assumed weather conditions (ambient temperature, wind speed, solar radiation) and the anticipated electrical loads to be transferred over the lines to ensure safe operating clearances and not to exceed safe conductor temperatures. Static line rating uses a constant limit based on some conservative assumptions making sure that lines do not overheat or sag more than allowed.

  9. What is DTCR?

    DTCR stands for Dynamic Thermal Circuit Rating. This approach uses real time information to identify the capacity of the transmission lines. Transmission line rating is changing continuously due to changing environmental conditions such as ambient temperature, wind speed, direction and solar radiation. Thus, more accurate information is generated resulting in increased capacity.

  10. Why is Dynamic Thermal Rating (DTCR) is better than static rating?

    DTCR allows the increase in transmission line capacity safely and securely, by 5%- 20% above static line rating level, by using real time information as opposed to using conservative estimates. This utilization of additional capacity could be achieved with modest cost as opposed to expensive investment in new transmission lines.

  11. Who are the customers and which utility Companies is SAS currently working with?

    In discussion with Tri-State (USA), and several other utilities in the US, Canada, Brazil, Europe and Africa to field test the SAS system in their operational environment.

  12. What advantage does SAS have over Competitors?

    Competing technologies measure either sag or conductor temperature of a single line. A single SAS system measures both sag and temperature directly of all the three phases. No competitors are measuring all three phases, temperature and stress/ strain with a single system. SAS solutions can give valuable information about the condition and remaining life of the conductor and assist the decision process regarding refurbishment, replacement or postponement of maintenance of the conductor. Last but not the least, SAS systems provide information to the control centre regarding ice buildup on the conductor. SAS sensors are wireless, battery-less sensors requiring no maintenance. They can be installed on live, energized lines without any alteration of the transmission line hardware.

  13. What are the benefits to the customer?

    Increase transmission line capacity with some modest extra investment. Increased reliability and security of the transmission line, well supported decision making on line capacity, conductor condition and expected conductor remaining life, resulting in the saving of millions dollars.

  14. When and how will SAS make money?

    We expect SAS to start generating revenues in 18 months. One part of the income will come from selling the SAS DTCR system, the second part from providing regular reports on monitored conductors for utilities as a long-term service.

  15. How much experience does the leadership have?

    The leadership has extensive and proven business, technology and utility experience. (See business plan for details)

  16. When will SAS system be ready for deployment?

    SAS is expecting to have a prototype ready by end of Dec, 2013 and Beta units around Q2-Q3 of 2014. SAS is in process of identifying Beta sites for these tests.

  17. When will SAS become cash flow positive?

    SAS will be cash flow positive in 2015.
