5 Common Power Quality Problems in Pakistani Factories — and How to Fix Them

Voltage sags, harmonics, and poor power factor cost Pakistani industry billions annually. Here are the top 5 issues and their solutions.

Power quality problems are silent profit killers. Our energy audit teams have identified the same five issues in factories across Karachi, Lahore, and Faisalabad time and again.

1. Poor Power Factor

Induction motors running at partial load drag power factor below 0.8, attracting DISCOS surcharges and oversizing transformers. Solution: Automatic Power Factor Correction (APFC) panels.

2. Voltage Harmonics

Variable frequency drives, UPS systems, and rectifiers inject harmonic currents that overheat transformers and trip sensitive equipment. Solution: Passive or active harmonic filters.
