Network Analysis

Comprehensive network analysis and evaluation of energy consumption values

The effects of poor quality electrical supply are often underestimated. They can trigger long, unplanned idle times, increased energy costs or early machine wear.

Circuit feedback (harmonics) signifies a substantial range of disruptions and influences on supply voltage. It occurs when consumers that have non-linear voltage-current characteristics or non-steady operating characteristics (switch-on or switch-off processes) are operating in an electrical grid. Many devices, such as computers and frequency converters, cannot tolerate voltages distorted by harmonics and therefore go into fault condition.

Most operating shutdowns can be avoided by timely monitoring of the network. Transparency can be gained by recording important electrical variables like voltage, current and frequency. Monitoring these parameters and recognizing potential savings early may save money.

The 3-phase power measurement modules integrated into the fieldbus-independent WAGO-I/O-SYSTEM 750 record and process all relevant variables in a three-phase supply network. The modules provide system operators with increased insight into energy consumption by specific machines and systems, as well as ability to perform comprehensive network analysis. Additionally, the system operator can optimize the supply to a drive or machine based on the measured values detected, thus protecting the system from damage and failure.

  • Additional heat and loss of mechanical stability at three-phase and alternating-current motors and generators
  • Shortened lifespan of incandescent bulbs due to increase in the filament temperature
  • Malfunctions in power converters, synchronizing devices, and switchgears
  • Influence on protective devices like distance protection, excess current protection, and differential protection
  • Measuring errors at induction and energy meters
  • Secondary failures in industrial systems due to uncontrolled switching off of equipment
  • Substantial current load on the neutral conductor
  • System crashes on personal computers, interface defects, performance losses, component failures, data problems, and equipment failures

Almost all operating shutdowns can often be avoided by timely monitoring of the network. Transparency can be gained by recording important electrical variables like voltage, current, frequency. Money can be saved by monitoring these parameters and by recognizing potential savings early.
