HVAC equipment can fail with voltage drops of just 10-15% lasting 1 second or longer (NEMA MG-1) What Are They? Brownouts are sustained periods of reduced voltage lasting more than one minute, ...
Researchers at the University of Lisbon in Portugal have developed a machine learning algorithm that classifies and predicts inverter failures in utility scale PV plants. The new algorithm monitors, ...
Kiwa PI Berlin has fixed faults in inverters at a PV plant in South Africa by using root cause analysis. The project had experienced up to 130 failures related to insulated gate bipolar transistors ...
