Providing insights into inrush current monitoring and analysis using portable Power Quality Analyzer – NP45

Overview Several power quality issues occur in an electrical system like harmonics, voltage swells, dips and harmonics. Inrush current is also one such power quality issue that leads to voltage dips thereby affecting the power quality of the network in proximity to the source of causing it. These are present only for a short duration …

Enhanced harmonic analysis with the help of Bar graph representation of harmonics in Power Quality Analyzer

Overview Nowadays, almost every industry undergoes issues related to harmonics due to the increase in usage of non-linear loads. As these loads are unavoidable because they perform important tasks like controlling or conversion, solutions to mitigate the ill effects of harmonics are to be devised. These solutions include passive filters consisting of detuned inductors and …

Understanding cause of VFD failures using Power Quality Analyzer – Rish PQA

Overview Induction motors are widely used in industries due to their robust construction and operation. The speed of an induction motor is not required to be the same always and this depends on the requirement of the process, unnecessary operation of an induction motor at full speeds demands more energy and hence speed control is …
