A transformer may not turn back on after being powered off due to several reasons, including thermal overload, which can trigger protective devices to prevent damage. Additionally, issues such as a blown fuse, a tripped circuit breaker, or faults in the control circuitry can also prevent re-energization. Furthermore, if the transformer has experienced insulation failure or other physical damage, it may require repair or replacement before it can operate again. Regular maintenance and monitoring are essential to ensure reliable operation.
