MEASUREMENT ON COMPENSATION CAPACITANCE IN INDUCTIVE NETWORK BY MICROCONTROLLER

AbstractIn the paper are presents the results of a practically realized prototype on an microcontroller circuit fordetermined on the compensation capacitance in inductive network. In energy networks with high inductiveload the reactive energy is high and therefore these networks operate with a low power factor. In suchnetworks to reduce the reactive energy are installed compensating capacitors. The solution in the paperdetermines the required capacitance in inductive networks to reduce reactive energy and increase the powerfactor to one unit. The realized measuring circuit, in addition to determining the value of the compensationcapacitor, determines the current, voltage, active power, active energy and reactive energy. The circuit isbased on Atmega 328 microcontroller and smart power meter PZEM004. The capacitance value is visualizedon an LCD display, and the values of current, voltage, active power, compensation capacitance and powerfactor are displayed on a serial monitor on the computer.Key wordsPower meter, Microcontroller, Measurement capacitance
