The Asset Performance Management System (APMS) is a comprehensive solution for real-time monitoring and management of transformers in the power system. It uses advanced technologies to optimize operations, improve reliability, and ensure grid safety. The APMS measures critical parameters like voltage, current, power factor, active power, reactive power, and apparent power, enabling early detection of faults for prompt maintenance actions. It efficiently manages transformer loads, preventing overloading or underutilization, and helps with load balancing and capacity planning for improved grid efficiency and sustainability. The APMS also facilitates the integration of new distribution substations, ensuring proper load distribution and promoting scalability and flexibility for future grid expansion. Overall, the APMS empowers utilities with smart metering and control, enabling proactive issue resolution and real-time data-driven decision-making, leading to a more efficient and sustainable energy infrastructure.
