Trane Power Factor Correction Trane Care Services Improve power factor of your chiller and reduce energy costs and carbon foot print Trane Care™ customized service solutions for building owners address operating performance, energy efficiency and environmental concerns. Trane Power Factor Correction will improve power quality and increase system distribution capacity. How the power factor affects your chiller installation Example: 200 kVA connected load from utility company to your building with an average power factor of 0.7 will result in available Your electricity bill – the facts Real Power of 200 x 0.7 = 140 kW. Utility companies bill their customers for two Real Power and Reactive Power. Real Power, What does a low Power Factor mean for you? measured in kW, is the working power that Utility companies often impose an economic is fully transformed into mechanical energy. penalty on customers with low power factors Reactive Power is the non working power as they must generate and supply surplus transformed by electrical motors to create current. This increases the energy costs. types of power consumption in facilities; a magnetic field used for their operation. This is measured in kVAr. Added to this the fact that a low power factor causes voltage drops and reduces an electrical What is the Power Factor? system’s distribution capacity. The Vector resultant of the two components, Example: In the previous example if the Real Power and Reactive Power, is called power factor is corrected from 0.7 to 0.9 Apparent Power, measured in kVA. The Power then the available real power increases to Factor (cos φ) is the ratio of the real power to 200 x 0.9 = 180kW up by 28% with the apparent power. same connected load. Example of power factor correction benefits Original Plant power factor = 0.7 Original reactive power 142 kVAr Original 140 kW (200 x 0.7) Available Real power Apparent power + 200 kVA Corrected Plant power factor = 0.9 Corrected reactive power 87 kVAr 180 kW (200 x 0.9) After correction How to improve the Power Factor – the Trane solution • Increase your system distribution capacity: Your electrical system’s branch By installing the Trane factory-designed capacity will increase through the reduction capacitor panel directly on the chiller, the of power losses in your distribution system. Power Factor is improved to 0.95 at full load. A Power factor correction of 0.1 will improve One capacitor panel is designed per chiller to the available real power by up to14%. correct the power factor of the chiller even • Improve power quality: Excessive voltage at part load conditions up to 0.88. Example: drops can cause overheating and premature Power factor correction from 0.7 to 0.95 failure of motors. Power factor correction decreases the reactive power up to 2/3. will minimize voltage drops in the system. • Achieve a greener system: Power factor This simple and quick to install solution done correction enables your organization to by a Trane factory authorized technician, become more environmentally responsible immediately works for you to increase the without having to reduce the amount of available distribution capacity and reduce working power available hence reducing energy costs. Return on investment in most your carbon foot print. cases will be less than two years. • Comply with local regulation: As national grids are stressed to the limit, social and Trane engineered quick ROI solution can be easily installed by a Trane factory authorized technician to address Trane Power Factor Correction – the benefits legislative regulations are introduced. The installation of Trane Power Factor Optimize the quality Trane Power Factor Correction is the Correction capacitors helps you comply and efficiency of your environmentally responsible, green solution with these local regulations. electrical distribution that will help you: • Reduce your energy costs: You can save up to 8% on your energy costs from chillers by increasing your chiller power factor closer to 0.95.
