Frequency adaptive harmonic current generator

A frequency adaptive harmonic current generator for generation of harmonic currents, comprising:

• a microcontroller board for controlling the generation of harmonic currents and a frequency adaptive operating function, wherein the frequency adaptive operating function enables continuously generation of harmonic currents at different frequencies;
• an electronic relay controlled and switched over a digital output of a microcontroller, a resistor and a transistor, wherein the electronic relay provides a steady duty cycle necessary for the generation of harmonic currents at different frequencies;
• a data collection unit, wherein, a voltage divider, a buffer and a current shunt are connected to the data collection unit for measurements of voltage and current harmonics, wherein, the data collection unit is configured to read current and voltage values and transfers the current and voltage values to a panel type computer;
• and
• the panel type computer includes a software for making, presenting and recording the measurements;
• external connections of the panel type computer are made through by USB connectors and a LAN connector;
• the panel type computer is configured to display the measurements to a user and has a push-button for switching on/off operations.
