Grounding Systems SunnyGround-Series Solar Photovoltaic Effective Grounding System 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 SunnyGround-Series Photovoltaic Effective Grounding System will provide the hardware and controls necessary to effectively ground the AC side of the system and satisfy the stringent utility requirements, making your solar installation as reliably protected from ground faults as traditional AC grounded systems.

When used in generator neutral, these devices will also limit the amount of the generator available Line to Neural fault current below the design limits set by the NEMA MG1 generators design standard. APT LZR-Series 2.4kV-15kV Neutral Grounding Resistor (NGR) Low Resistance Grounding System Brochure HZR-Series High Resistance Grounding (HRG) System An appropriately sized APT HZR-Series High Resistance Grounding (HRG) System provides increased continuity of service due to the ability to operate a power system under a ground fault condition. A ground fault alarm is provided to alert the operations personnel to assist in identifying and correcting the ground fault condition and consider orderly shut down as required to clear the fault.
