Abstract
A system, for measurement of temperatures and detection of faults of parallel transformers in a DDC enclosure, that includes a first transformer and a second transformer arranged in a parallel configuration that deliver power to components of a building management system (BMS). The system also includes a direct digital control (DDC) circuit that controls power delivered through the first and the second transformers to the components of the building management system (BMS). The system further includes a first temperature sensor, operationally connected to the DDC circuit, which measures the temperature of the first transformer. Furthermore, the system includes a second temperature sensor, operationally connected to the DDC circuit, which measures the temperature of the second transformer. The DDC circuit determines a difference between the first temperature and the second temperature to predict a fault in the first transformer or the second transformer.
