A Grounding Bank Design Guideline To Meet The Effective
1. Background Solectria prepared this document to aid the PV developers with the design of grounding bank in order to be compliant with the effective grounding requirements of utilities that
In general, effective grounding can be achieved with a grounding transformer as shown in Figure 1 (a). If the PV inverter has an internal transformer with the grounded wye to delta configuration, a grounding reactor can be used instead by accessing the neutral point of the inverter transformer.
Effective grounding in photovoltaic (PV) systems is the creation of a low-impedance reference to ground at the AC side of the inverter—or group of inverters—that is designed to be compatible with the distribution network's requirements and existing grounding scheme.
It is a mandatory practice required by NEC and IEC codes to protect both equipment and personnel from damage and electric shock hazards. This article covers grounding in PV systems, which differs slightly from standard grounding systems.
Utility requirements for effective grounding play a key role in mitigating potential temporary overvoltages that may arise from PV inverters. When a line-to-ground fault occurs in a three-phase grid distribution system, substation equipment typically detects it and opens the related circuit.
