Parallel transformer temperature measurement and fault detection system and method for DDC enclosures

A method comprising:

• measuring a first temperature of a first transformer on a first temperature sensor, wherein the first temperature sensor is operationally connected to a direct digital control (DDC) circuit;
• measuring a second temperature of a second transformer on a second temperature sensor, wherein the second temperature sensor is operationally connected to the direct digital control (DDC) circuit, wherein the first transformer and the second transformer are arranged in a parallel configuration that delivers power to components of a building management system (BMS);
• predicting a fault in the first or the second transformer, by the direct digital control (DDC) circuit, by determining a difference between the first temperature and the second temperature, wherein the DDC circuit controls power delivered through the first and the second transformers to the components of the BMS;
• wherein the method comprises, initiating a failure alarm and informing the BMS operators, when the DDC circuit predicts that a fault has occurred in any of the first or second transformers.
