The life-expectancy of Power Transformers, is assumed to be 35-40 years. However, there is no literature expressively quantifying the same. Unforeseen failures of old transformers in the Grid-network result into system disturbance or cascade trippings. Therefore, it is of utmost importance to obviate such situations to safe-guard the grid-system from the aforesaid disturbances and losses. […]

In high-voltage laboratories, achieving accurate, repeatable, and IEC-compliant Partial Discharge (PD) measurements is becoming increasingly challenging. Modern test environments are exposed to significant RFI/EMI, switching spikes, harmonics, and ground noise, all of which overlap the IEC 60270 PD detection band (40–300 kHz). These disturbances can mask true PD activity, lead to false readings, and compromise […]
