Continuous monitoring and power quality analytics

Power quality problems cost U.S. businesses billions of dollars annually in lost revenue, unplanned downtime, scrapped product, damaged equipment, and lost data.

Although some power problems can be traced to the utility, most root problems occur from internal distribution or internal loads. The growing distribution of electronic components renders connected loads increasingly sensitive to any disturbance in the power supply - even microsecond power disturbances which happen often enough can have disastrous effects on plant equipment, productivity, and energy consumption.

Uninterrupted power is a critical parameter for the smooth operation of all connected loads and resources. But it is often difficult and sometimes impossible to determine the causes of power problems after the fact, as they frequently occur only briefly, for milliseconds or microseconds. Typically, power quality monitoring has been used for reacting to problems - using data on occurrences after the event to develop a solution - rather than creating a proactive solution. 

Continuous monitoring of power quality makes it easier to draw a relationship between an outage such as the failure of a machine and its cause. With its real time capabilities, continuous monitoring puts facilities in a proactive position by giving them the tools to increase system reliability.

Indicators of power quality problems:

  • Voltage surges or spikes
  • Voltage dips/sags
  • Under voltages
  • High-voltage spikes
  • Frequency variation
  • Power sags
  • Electrical line noise (RFI or EMI)
  • Brownouts
  • Blackouts
  • Very short interruptions
  • Long interruptions
  • Voltage Swell
  • Harmonic Distortion
  • Voltage fluctuation
  • Noise (superimposing of high frequency signals on the waveform of the power-system frequency)
  • Voltage unbalance
