How often should transformers be inspected?

Transformers should typically be inspected once or twice a year to ensure their proper functioning and to identify any maintenance needs before issues arise. This frequency allows for monitoring of the transformer's condition and any potential degradation that may occur over time. Regular inspection is vital for maintaining efficiency and safety in electrical systems, as transformers can develop issues like insulation breakdown, overheating, or other mechanical failures if not properly maintained.

While various maintenance schedules may exist depending on specific operational requirements and manufacturer recommendations, inspecting transformers once or twice a year strikes a balance between practical oversight and resource allocation for maintenance activities. This timing is generally sufficient to catch any significant changes in performance and allow for repairs before they escalate into more significant problems.
