Measurements · Power Quality

Power quality measurement and analysis

Find phase unbalance, low power factor, harmonics, fast and slow voltage fluctuations and anything else that harms your system and your productivity.

  • Recording with power analyzers at switchboards and substations
  • Diagnosis of voltages, currents, harmonics and symmetrical components
  • Assessment against current regulations and international standards
  • Mitigation recommendations: power factor correction and harmonic filtering
  • Technical report with prioritized findings and an action plan

Problem in your installationWhat it causes
Low power factorLosses from reactive current flow and penalties on your electricity bill.
Phase unbalanceNegative-sequence currents that overheat motors and damage bearings through pulsating torque; excess neutral current.
Harmonics in the electrical systemOverheating of conductors, transformers and equipment; possible overvoltages due to resonance.
Transient voltage sagsCaused by starting large loads or a low short-circuit level; can trip the busbar along with all its loads.
Measurements · Thermography

See the heat before it becomes a fire

Thermography uses cameras that capture the infrared spectrum to reveal the heat radiated by each component. This lets us detect dangerous temperatures in contacts, conductors and equipment that can cause failures, or even fires, if not corrected in time.

  • Improve productivity and avoid plant shutdowns
  • Reduce fire risk and insurance costs
  • Temperature-versus-load list for every inspected point

Before the shutdown

Hot spot survey of:
  • Power and lighting switchboards, MCCs
  • Power and distribution transformers
  • Motors, pumps, fans and drives
  • Capacitor banks
  • Data centers and backup UPS

During the shutdown

Correcting the findings:
  • Tightening terminals and fastening bolts
  • Replacing terminals and protection devices
  • Phase balancing and conductor replacement
  • Replacing insulation and motors
  • Cleaning, lubrication and air filters

Commissioning

Verifying the maintenance:
  • Check that hot spots were corrected
  • Verify balance improvements
  • Verify terminal replacements
  • Temperature-versus-load list
  • Points requiring power quality analysis

CS

Carlos Sagredo Vera

Electronic Engineer · MSc in Energy Efficiency

Electronic Engineer in Instrumentation (Pontificia Universidad Católica de Valparaíso, PUCV), with a Postgraduate Diploma in Electric Power Systems (PUCV) and an MSc in Energy Efficiency and Climate Change (Universidad Complutense de Madrid), and over 30 years in power quality. His thesis project, the SADME data acquisition and electrical measurement system, with three voltage and three current inputs for measuring transients, was used in the university's laboratories to train 15 generations of engineers. At ElectroChile.com he led the hardware and software development teams, whose work includes the service quality meters developed for the SEC (Chile's electricity regulator) and fault recorders installed in substations for large-scale mining and power generation. He has advised CODELCO, CMPC, Enel, Gener and SAESA, among others, on power quality and energy efficiency.
