What is a Class A Power Quality Meter?<\/p>

A Power Quality Meter (PQM) is an advanced device that records and monitors parameters like:<\/p>

  • Voltage and frequency variations<\/li>
  • Harmonics and distortions<\/li>
  • Power factor<\/li>
  • Load profile and consumption trends<\/li><\/ul>

    A Class A PQM, certified under IS 14697 standards, guarantees the highest level of accuracy, ensuring that data shared with MSEDCL is precise and reliable.<\/p>

    The Power Quality Meter shall be capable of recording and analyzing power quality parameters in accordance with IEC 61000-4-30 Class A methodologies and shall also meet the provisions of IEC 62586-2<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
