- Motor loads contribute to 60%-70% of total energy consumption of industrial sector.
- Replace faulty motors with High Efficiency Motors (HEM), preferably with Eff1 classification. Eff3 motors should be avoided.
- Install variable speed drive which could control motor speed according to load demand.
- Balance the 3-phase power supply.
- Move liquid more efficiently - avoid unnecessary pipe fittings & undersizing of pipes.
- Select the right pumps for the intended application
- Avoid oversizing of pumps.
- Install variable frequency/speed drives for precise speed control.
Improve Your Power Factor
Having a low power factor means your machine is inefficient and requires more electricity to perform its tasks. By increasing your power factor, your machine will use less electricity to achieve the same results, and this will reduce your monthly electricity bill.
In addition, you will avoid paying a 1.5% to 3% Power Factor surcharge, which SESB imposes should your power factor drops below 0.85.
Power factor can be improved by taking the following measures:
- Install Capacitor banks, Synchronous generators or synchronous motors.
- Minimize operations of idling or lightly loaded motors.
- Avoid operating equipment above its rated voltage.
High efficiency motors operate at higher power factor compare to standard motors.
