The IEEE Vehicular Technology Society (VTS) Philadelphia Chapter is holding a technical meeting. The topic is Electrical Substation Battery Systems. Our speaker is John Kim, Director of Industrial & Utility Markets at EnerSys. This presentation discusses technical aspects of 125 V dc battery systems used in electrical substations. Utility and traction power substations typically use 125 V dc battery systems to provide uninterrupted backup power to protective relay systems, switchgear controls, and switchyard equipment. Batteries are selected based on owners’ preferences and applications. They are sized based on the anticipated dc load profile upon a loss of power. Load profiles often include first minute equipment operation, an 8-hour loss of power, and expected switching operations to restore power. IEEE 485 is a recommended practice for sizing lead-acid batteries for stationary applications. Mr. John Kim will give a presentation on the history of batteries used in substations and today’s latest battery technologies. Attendees may apply for 1.0 PDH provided through the IEEE Certificates Program, accepted in all states. Send $5.00 (USD) payment to Brandon Swartley via Zelle at [email protected] and complete the online evaluation at https://r2.ieee.org/philadelphia-vts/forms/. Evaluation form must be completed and payment received within one week to receive PDH certificate.
