Direct current (DC) circuit protection | Eaton PSEC
9:59
Compared to alternating current (AC), direct current (DC) flows consistently in one direction therefore it requires additional mechanisms to safely interrupt circuits. Christy McElhinny, Field Application Engineer, explains the critical role DC circuit protection has within energy transition applications, which inherently use DC energy. This is especially true as energy transition applications such solar (also referred to as photovoltaic (PV) systems), battery storage, and wind generation are projected to increase in adoption. Though DC circuit protection has overlap in ratings familiar with AC systems, there also unique requirements of DC circuit protection within electrical vehicles (EV), EV chargers, energy storage, and PV systems. Christy also explains how a PV system is designed and operates by following a PV schematic. Also, the different design options that can be engineered and at which point DC circuit protection is required to be installed.
