Modular precharge circuit

摘要: Provided is a modular precharge circuit capable of rapidly recharging an equipment path prior to insertion fuse or breaker. The includes switch begin the operation precharging, and charge indicator indicate appropriate charging has occurred. Charging occurs through use resistive network which receives inrush current due capacitance in path. Once been precharged desired level, signifies such complete unit removed whereafter module and/or breaker inserted. further fusing element alarm wherein when enters fault state that open, situation. Additionally, verifies not precharging indication short exists.
