Transformers sit at the centre of every utility network—quietly doing the heavy lifting of voltage regulation and power delivery. When they start degrading, the impact isn’t only “a failure event.” It shows up earlier as higher losses, unstable voltage, nuisance trips, repeated alarms, and corrective work that keeps eating crews’ time. The tricky part is that transformer health rarely drops off a cliff overnight; it erodes in patterns—thermal stress, moisture, insulation ageing, tap changer wear, bushing issues—until one day the asset crosses a threshold you didn’t see coming.
