IoT Substation Battery Bank Impedance & Health Tester
Automated AC injection impedance tester measuring milliohm internal resistance of substation lead-acid batteries to prevent DC blackout.
Project Overview
Monitors emergency backup battery strings in electrical substations. Periodically injects small AC test currents to measure internal cell impedance, terminal voltage, and ambient temperature, alerting engineers to deteriorating cells before trip coils fail during grid faults.
