Seasonal Variation of GPS-Derived the Principal Ocean Tidal

The classical harmonic analysis (CHA) method only can be used to obtain the harmonic constants (amplitude and phase) of ocean tide loading displacement (OTLD). In fact, there are significant seasonal variations in the harmonic constants of OTLD. A moving harmonic analysis (MHA) method is proposed, which can effectively capture the seasonal variation of

Code of Practice for Energy Efficiency of Electrical

''Harmonic'' means a component frequency of a harmonic motion (as of an electromagnetic wave) that is an integral multiple of the fundamental frequency. For the power distribution system in Hong Kong, the fundamental frequency is 50 Hz. ''Installation'' means the wiring installation together with any equipment connected or

For example, on a 50 Hz supply, the 5th harmonic is 250 Hz, 7th harmonic is 350 Hz. Other sources of harmonics in buildings include computer equipment, VSDs, ACVV/VVVF lift drive systems and electronic ballasts etc. The presence of harmonics on the power distribution system will definitely reduce the efficiency of the system.
