**2. Architecture of the power quality monitoring system**

The architecture of the power quality monitoring system is planned for specific purposes which are to detect, to store, to download and to display the fault signals while being on operation or being done later on. The main structures are divided into 5 circuit boards. The block diagram of the architecture of the power quality monitoring system is shown in Fig. 1.
