  • PIC18F2520 MCP3909 3-Phase Energy Meter Reference Design - Meter Test Results and Adapting the Meter Design for other Requirements
    here with approximate bration/test on each meter that we ship as demo calibration times (using 128 line cycle accumulation at boards. Steps have been taken to ensure you receive 50 Hz) an energy meter 'out of the box' that performs to the above meter specifications, but the equipment and GAIN (5A, 220V
  • A Risk-Based Approach to Energy Conservation
    thinking in all process engineering activities. Consider improved building technology. Buildings and the built environment represent a majority of energy consumption, and many facilities are old and outmoded. Use LEED certification scorecards as guidance, and look to new building design codifications being
  • Using EC Plug Fans to Improve Energy Efficiency
    center cooling system is a primary target for energy efficiency improvements. An Emerson Network Power analysis of data center energy usage found that cooling. systems-comprised of cooling and air movement equipment-can account for. approximately 38 percent of energy consumption. Recently, Emerson
  • Improving Energy Efficiency in Pharmaceutical Manufacturing Operations
    By Christina Galitsky, Sheng-chieh Chang, Ernst Worrell, and Eric Masanet, Berkeley National Laboratory, Environmental Energy Technologies Division Properly sized pipe diameters. Increasing diameters can reduce energy consumption to 3%. Heat recovery for water preheating. Up to 90%
  • Improving Energy Efficiency in Pharmaceutical Manufacturing Operations
    a leak rate equal to 20% to 50% of total capacity. Leak maintenance can reduce this number to less than 10%. Fixing leaks pays off, reducing annual energy consumption by 20% [16]. The magnitude of the energy loss varies with the size of the hole in the pipes or equipment. A compressor operating 2,500
