Application software for measurement, acquisition and displaying the distribution of pulses irregularities sinusoid voltage on the generator, by using the device PDA Watch - Partial Discharge Monitor is developed in LabVIEW software. Application software is running on a PC that is connected to the RS-485 network that provides access to PDA Watch devices and PLCs. In addition to the acquisition of data from these devices, the software enables data acquisition from a central database via the Ethernet interface. For the purposes of accepting data from PDA Watch devices user-defined protocol was developed. LabVIEW supports a huge number of protocols and interfaces and provides the ability to create user-defined protocols, as well as easy connection to ODBC and SQL-compatible databases.
