POWER QUALITY ANALYSIS

Power quality analysis is the process of monitoring & analysing an electrical power supply to identify & address issues that can negatively impact equipment performance, efficiency, & safety. It involves measuring & analysing various parameters like voltage, current, frequency, harmonics, & transients.

Why Power Quality Measurement is Important?

  • Preventing Equipment Malfunctions & Downtime: Power quality issues like voltage sags, swells & harmonics can cause sensitive equipment to malfunction.
  • Improving Efficiency & Reducing Energy Costs: High-quality power ensures equipment operates at optimal efficiency.
  • Ensuring Compliance with Standards & Regulations: Many industries have specific power quality standards that must be met.
  • Protecting Sensitive Equipment & Data: Essential for data centres, hospitals, & research centres.
  • Optimising System Performance & Reliability: By identifying & addressing PQ issues, businesses can optimise performance.

Benefits of Power Quality Analysis:

  • Identify Disturbances: Distinguish a Power Outage & a Voltage Sag
  • Provide Data for the Equipment specification.
  • Verify protection settings & determine the cause of the problem.
  • Determine the use of Power Conditioning Equipment.
  • RMS Operational & Demand meeting - High Accuracy Metering
  • Control Functions – For triggering or controlling Capacitor Bank, Transformers, etc.

OTSPL performs with a Class A (Metrel) Power Quality Analyser, which has a continuous 7-day data recording facility as per standard IEEE519 & automatic report generation software.
