Astec E Pac™ Introduces Automatic Power Factor Corrector

The Astec E Pac™ power factor corrector senses the power factor and pulls in banks of capacitors to offset the reactive load, thereby keeping the power factor high.

Astec, Inc., an Astec Industries company, introduces the E Pac automatic power factor corrector to reduce electrical costs. Running a plant at anything less than 100% the rated capacity can result in reduced electrical efficiency.

The Astec E Pac power factor corrector uses automatic capacitors which vary the amount of correction supplied to the electrical system. Automatic capacitors are made up of banks that are switched off and on by a microprocessor controller based on the plant electrical load at any given time. The Astec E Pac power factor corrector senses the power factor and pulls in banks of capacitors to offset the reactive load, thereby keeping the power factor high. 

Power factor is the percentage of consumed power versus supplied power. A low power factor can waste energy, result in inefficient use of electrical power, and often lead to higher energy bills. A power factor corrector accounts for the difference in power consumed compared to power supplied in order to maximize efficiency. 

Utilities often impose a reactive power charge for "non-working" power, or power that has to be made up due to inefficiencies at the load source. Power factor correction capacitors will improve the energy efficiency of any electrical system, which may mean a plant can avoid the reactive power charges levied by electricity suppliers.
