This video demonstrates the complete process of replacing the Energy Accumulator Assembly in OLTC systems. Our technical expert shows step-by-step procedures including safety precautions, tools required, disassembly process, new part installation, and final testing procedures. We begin by isolating the transformer and discharging any residual energy. Next, we carefully unbolt the outer housing, exposing the accumulator spring mechanism. It's crucial to inspect the driving shaft for any signs of wear at this stage. Then, we insert the new, precision-engineered accumulator assembly from Sairaj Groups, ensuring correct alignment before torquing the bolts to the manufacturer's exact specifications. Finally, a manual switching test confirms smooth operation.
