) Results: Total harmonic distortion (THO) is decreased from % 1.7 to 0.9 in voltage and from % 14.6 to 10.5 in current. It should be considered that the efficiency of the system is varying with the system variables and changing of the loads. The fact is the efficiency of the passive filters changes depending on the other variables of the grid. Power factor of the transformers is increased from 0.982 to 0.995 after application. 1.2 TR15-16 (Measurements are taken common because of parallel operation) Results: Total harmonic distortion (THO) is decreased from %4.3 to I, I in voltage and from % 16.6 to 7.2 in current. Power factor of the transformers (TFP) is increased from 0.986 to 0.997 after application. 2. Application of "Reactive Power Compensation System with Passive Harmonic Filter" and "Parallel Active Harmonic Filter" to the ID Fan motor transformer of rotary kiln (6.3/0.69kV, 1636kVA). Results: Total harmonic distortion (THO) is decreased from % 12.4 to 5.8 in voltage and from %35. 5 to 12.7 in current. Power factor of the transformers (TFP) is increased from 0.942 to 0.992 after application. 3. Application of "Reactive Power Compensation System with Passive Harmonic Filter" and "Parallel Active Harmonic Filter" to the Rotary kiln main drive motor transformer (6.3 I 0.69kV, 900kVA). Results : Total harmonic distortion (THO) is decreased from % 7.7 to 2.3 in voltage and form % 66.7 to 6.5 in current. Power factor of the transformers (TFP) is increased from 0.832 to 0.997 after application.

ISO 50001 is the Energy Management System Standard that focuses on sustained energy performance. It's the first management system standard that integrates performance requirements into the standard. What is SEP? SEP is Superior Energy Performance, a U.S. Department of Energy sponsored program that supports and recognizes continual improvement of energy performance. It adds additional management system requ irements and performance verification to ISO 50001. Why Should I go for ISO 50001/SEP? How does it benefit me? ISO 50001 /SEP provides a systematic approach to identifying and exploiting energy performance improvement opportunities and the structure to sustain them. • Energy Management Benefits: Companies have seen 10-15% savings from non-capital projects and an additional 10-15% from capital projects • Certification Benefits: Third-party oversight that assures the system remains effective by providing routine performance evaluation, expert insight, and accountability. • Financial Benefits: Many have realized incentives from government and util ities and their system provides protection against rising energy costs • Marketing Benefits: The ability to reduce your environmental footprint and international recognition from a standard that is being adopted around the globe. Early adopters have experienced significant (and sometimes surprising) performance improvements! These savings have often come with little or no capital investment. I already have ISO 14001 . Isn't that good enough? A robust ISO 14001 could also encompass areas of energy usage. However, ISO 50001 is based on a more detailed review, planning, measurement, and analysis specific only to energy performance that isn't covered within the fundamentals of ISO 14001 . 15
