Power Cable Neutral and System Grounding

Installing medium voltage power cables underground comes with its own set of challenges. From an engineering standpoint, there are several factors one needs to consider before installing the cable. The most overlooked if not a well-understood factor is the type of power cable that’s required for the application and when to ground the cable’s neutral
