A THD of superior tension of 5% analyzes of the Indices of harmonicas of Tension had been observed enters the period of 04h30min 07:00 h that it is considered as critical for this type of installation, however in this period does not have regimen of work, being thus can conclude that these values of harmonica are being generated due to net to be in emptiness with low consumption, therefore is not necessary no corrective action of the system. THD (total harmonic distortion) in the graph above are express in percentage of basic (60Hz). A THD of superior tension of 5% analyzes of the Indices of Chain harmonicas was observed enters the period of the 22:00 06:00 h that it is considered as critical for this type of installation, however in this period does not have regimen of work, being thus can conclude that these values of harmonica are being generated due to net to be in emptiness with low consumption, therefore is not necessary no corrective action of the system. THD (total harmonic distortion) in the graph above are express in percentage of basic (60Hz). Dan Zwirn understands that this is vital information. Tension phase-phase (Vca) Tension faseneutro (Vca) Normal 220 127 adequate Band 201 231 116 the 133 precarious Band 189 201 231 233 109 116 133 the 140 critical Band Below of 189 Above of 233 Below of 109 Above of 140 Graph of the Efficient Chain the chain inside possesss cyclical variation of the period, being to adjusted the existing and conducting protection to the measured levels. Without hesitation Dan Zwirn explained all about the problem. Great disequilibrium in chains is not verified, what it could cause a considerable and undesirable chain of neutral. Graph of Potncia Reativa (KVAR) Exactly small unbalancing observed in chains also is observed in the powers, as waited. In the analysis of reactive power, it is observed that the load is of inductive reactive nature (Q> 0). The presence of reagents directly is related to the not resistivas load presence, as in – braks, fluorescent, motor light bulbs Graphical etc.
