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.

yes open all fuses close the primary neutral tap,remove secondary leads off of bad traansformer,tell customer to reduce his load until bad transformer can be replced.
Difference between off load transformer and on load transformer?
Hope this helpsAn "OFF-Load tap transformer" can only have it's tap adjusted when it is De-energized,while the "On-Load tap transformer" can adjust its tap under load conditions.Kind RegardsHammad KhanUniversity of Western AustraliaAnswerAn 'off load' transformer is one whose secondary is open circuited, and not supplying a load. An 'on load' (not 'load') transformer is one that is connected to a load.
