Abstract
U ovom radu opisano je mjerenje efektivne vrijednosti struje i napona niskonaponske elektroenergetske mreže putem integriranog kruga LTC1966 i senzora ACS712. U svrhu mjerenja frekvencije i faznog kuta dvaju signala sinusnog valnog oblika predloženo je konceptualno rješenje u obliku dvaju optoizolatora čiji su bipolarni fototranzistori u spoju pojačala sa zajedničkim emiterom. Mjerenja se izvršavaju A/D pretvaračem integriranim u mikrokontroler te se vrijednosti mjerenja očitavaju putem web aplikacije MQTT posrednika. Komunikacija mikrokontrolera s MQTT posrednikom je izvedena putem bežične veze uz MQTT protokol.
Abstract (english)
Subject of this thesis is measurement of root mean square values of current and voltage in low voltage power networks via LTC1966 integrated circuit and ACS712 current sensor. In purpose of measuring frequency and phase shift of two sinusoidal waveforms proposed solution is in form of two independent optocouplers with its bipolar phototransistors in common emitter configuration. Measurements are done via microcontroller's integrated A/D converter and results of measurement are delivered via MQTT broker's web application. Communication of microcontroller and MQTT broker is done wirelessly via MQTT protocol.
