These systems now essentially depict a part of asset health management frameworks, especially in the working environment where transformers experience fluctuating load and environmental conditions.
• Partial Discharge (PD): Partial discharge monitoring is a predictive maintenance activity required for identifying insulation defects inside transformers that can culminate into severe faults if not corrected. Small electrical discharges occurring in weak areas, mostly in cables, bushings, or insulation, are detected by these systems. Proper proactive disposal to smaller risks may be taken by utilities in their PD decision in real time-offering trend analysis to go with programs to correct. The PD systems are often adopted more in older grids and substations where insulation wear occurs. AI integration allows for enhanced prediction accuracy and failure analysis, rendering PD monitoring an essential layer in comprehensive transformer health assessment strategies.
• Others: This set includes temperature sensors, monitoring for load tap changers (LTC), moisture sensors, and thermal imagers. These are the supporting systems that consolidate the transformer health profile by monitoring ambient and winding temperatures, moisture in insulation oil, and changes in operational load. LTC monitoring keeps voltage levels from drifting; temperature measurements are vital under harsh climate swings. These technologies are crucial in distribution networks and renewable energy scenarios. The thrust for integrated platforms leads to merging of different sensor systems into consolidated monitoring solutions that allow operators a 360-degree view of the transformer health and operational stability.

BY APPLICATION
