SUMMARY

The discussion centers on the implementation of power factor correction using capacitors in industrial motors with a power factor cosine of 0.69. Capacitors were installed downstream from the metering devices, raising concerns about accurate power factor readings since meters do not register apparent power. The power company requires a power factor close to 1 for grid compliance, emphasizing the importance of proper installation for accurate metering and compliance.

PREREQUISITES
  • Understanding of power factor concepts and calculations
  • Familiarity with electrical metering devices
  • Knowledge of capacitor banks and their role in power factor correction

I am sure this has been discussed many times before but here goes. I was recently working on motors with a power factor cosine of 0.69. To counteract this the company installed banks of capacitors to get the power factor near 1. My question is this, the capacitors were installed downstream from the meters. Surely it needs to be the other way round as meters cannot register apparent power?

The power company prefers you to show a power factor near 1 to the grid. How you do it is your problem.
 
Nah, its not my problem.
