Monitoring AC Line Voltage remotely over the Internet
Monitoring AC Line voltage is an important part of many systems.
Our Flex Scada device line offers a wide array of options for monitoring ac voltage.
Monitoring line voltage is important for situational awareness and quality/verification purposes.
When an input is configured to accept an AC voltage it computes the following metrics and makes them available for logging and logic rules
- Vrms
- Frequency
- Vpk
With the addition of a Current Transformer or Sensor the following metrics are also available
- Watts (Real Power)
- Power Factor
- Lrms
- Lpk
Example Uses:
- Wind: Measure generator output voltage before charge controller to get turbine rpm info from ac frequency, can be used to control dump load or braking / high speed shutdown
- Hydro: Measure Generator Output Voltage, Generator RPM and Generator Frequency. Frequency can be used to cycle dump ballast loads to regulate output at a constant 60hz
- Grid Independent Solar: Useful for verifying inverter output voltage and graphing output under various load conditions.
- Speed Hump: Useful for verifying vehicle count, generator rpm, watts per vehicle, vehicle speed, hump conversion efficiency, vehicle weight and more (FlexScada devices have been used in speed hump/bump energy recovery installations across the world)
- Standby Generators/ Diesel Gen-sets / Backup Power Systems: Commonly used to verify output health and log runtime over the internet.
- Pedal Power: Used primarily by prepers and educational intuitions, Flexs Q3 Devices have been used to monitor the output and display/graph it in real-time.
- Industrial: Commonly used for logging line quality and brownout conditions
- Grid: Monitoring voltage at many points throughout power grids is an important part of sag mitigation and brownout protection. Flex Scada devices have been used throughout the world by leading power suppliers to give them the situational awareness they need to deliver the best power.
- Backup Power Systems: We’ve had several clients develop there own backup power systems around the Flexs Q3 smart plc, with it’s rapid response and high resolution analog inputs the flexs Q3 device could detect the fading power as it went down and quickly switch on an inverter.
