Insulation fault detection in rotating machinery using Partial Discharge (PD) has been a hot research topic over the last decades. In recent years, attention has also been paid to low voltage machines, following the advent of wide bandgap semiconductor devices. This paper presents a low-cost, modular, and full-digital PD monitoring device, particularly suitable for deployment in large industrial plants. The proposed innovative solution allows us to implement a monitoring network, ensuring complete coverage in large industrial plants and continuous monitoring of critical machinery.
