Systems, methods and devices for monitoring temperature are presented herein. A method of monitoring temperature in a system, such as a capacitor bank, is disclosed. The method may include: receiving first device temperature signals indicative of the temperature of a first device over a predetermined period of time; receiving second device temperature signals indicative of the temperature of a second device over a predetermined period of time; determining a first rolling average temperature for the predetermined period of time from the first device temperature signals; determining a second rolling average temperature for the predetermined period of time from the second temperature signals; and triggering a disconnect event in response to a determination that either the first or the second rolling average temperature is greater than a predetermined maximum working temperature.
