Power Factor Correction Installation
Micron Group electricians and engineers supply, install and integrate three phase PFC units to commercial and industrial buildings ultimately improving efficiency and saving thousands of dollars in energy costs, and tons of CO emissions.
What is Real Power?
When it comes to three phase AC power it is important to know the difference between Real and Apparent Power. Real power is the amount of power your equipment uses, while apparent power is the total power supplied to your building from the grid.
Three Phase Installations, Why is Cos Φ Important?
A building functions at it most efficient when it is at a power factor Cos Φ of ‘one’, or unity, meaning it is neither inductive nor capacitive overall but purely resistive.
The efficiency of your typical three phase installation is hampered by the accumulative effect of various highly inductive loads (e.g. lifts, motors and fluorescent lighting). These loads drag the power factor down, increasing the apparent (supplied) power from the grid relative to actual usage. While a physics or electrical engineering degree helps in calculating these effects, a Power Factor Correction unit takes the headache away by monitoring the buildings power factor in real time and stepping in banks of large capacitors to correct this issue and restore the building to optimal efficiency.
