Power monitoring and harmonic problems in the modern building

Personal computers are responsible for generating the majority of harmonic-related problems in the modern building. It is becoming increasingly problematic in commercial buildings, especially where large quantities of computers are present. The problems caused by personal computers can now be quantified by the use of digital power monitoring systems. Current and voltage values are no longer adequate to understand the characteristics of electrical loads, as it is important to understand the complexity of the load. Therefore, a graphical picture of the load can reveal move answers to apparently complex problems.
