With the rapid increase in the construction of solar farms and the conversion of DC voltage to AC voltages, the question of how to provide effective grounding to the AC side of the system has taken center stage. Many utilities are requiring that solar installations are effectively grounded. An appropriately engineered APT ZZX-Series Zig-Zag Effective Grounding System will provide the hardware and controls necessary to effectively ground the AC side of the system. The ZZX-Series is designed to satisfy stringent utility requirements for impedance, fault current, fault X/R ratio, and continuous current. Complying to these requirements with the proper control scheme will make your solar installation as reliably protected from ground faults as traditional three phase AC grounded systems.
