Abstract

A system (100), for measurement of temperatures and detection of faults of parallel transformers in a DDC enclosure (101), that comprises a first transformer (102) and a second transformer (104) arranged in a parallel configuration that deliver power to components of a building management system (BMS). The system (100) also comprises a direct digital control (DDC) circuit that controls power delivered through the first and the second transformers (102, 104) to the components of the building management system (BMS). The system (100) further comprises a first temperature sensor (108), operationally connected to the DDC circuit, which measures the temperature of the first transformer (102). Furthermore, the system (100) comprises a second temperature sensor (110), operationally connected to the DDC circuit, which measures the temperature of the second transformer (104). The DDC circuit determines a difference between the first temperature and the second temperature to predict a fault in the first transformer (102) or the second transformer (104).
