“…In [17], they made a smart energy meter for power quality monitoring using a voltage sensor (step down transformer with voltage distribution coil), current sensor (ACS712-30A), measuring harmonic data using a harmonic analyzer that showed through a personal computer. Author in [18] presents the design and experimental Low-Cost Harmonic Analyzer (LCHA) on a car inverter. Researcher in [19][20] Interfacing of MATLAB with Arduino.…”
