There are various solutions currently employed to help mitigate potential problems of ground faults and impedance between the two separately-derived grounds—at the static-switch bypass and the double-ended substation. A transformer can be installed at the input of the static switch so that the neutral-to-ground bond established at the static switch will come from a separate source. This approach, however, can be costly, and the required transformer can be extremely large. Also, the transformer will contribute to inrush and additional impedance. But it may be of benefit in limiting maximum fault current available downstream from the UPS system.

HRG is not commonly used on a low-voltage system. The intent is to introduce a resistor to limit the current that flows at the neutral and ground bond, where the ground-fault current transformer monitors fault current (see figure 3). This method is difficult to implement, because it requires calculation of system capacitance and requires fine-tuning of the resistor in the field. It is also dangerous, requiring highly trained personnel to monitor the ground-fault alarm and then trace through the distribution system and isolate the source of the fault. Human error is already a major source of data center power loss. It does not seem a good idea to introduce yet more human intervention to trace and isolate fault current. In addition, the setting for the ground-fault sensors needs to be revisited any time a significant load is added that may change the system capacitance. Ashlok.in It may seem that the solution is as simple as providing a zone-interlocking relay-protection scheme from the double-ended substation down to UPS static switch, and a distribution switchboard downstream of the UPS system. But ground-fault coordination is very difficult to design and install. Also, the static switch will transfer from the UPS module at a much faster speed than any fast-acting relay.

The design engineer should coordinate with the client to establish design parameters based on economics and level of required reliability for mission-critical facilities and ensure that the final product is a facility that meets all of the client's long-term operational requirement.

The earthing transformersmay in addition supply a local auxiliary load. Theearthing transformer creates a neutral point for a network. Simply put, a grounding transformer is used to provide a ground path to either an ungrounded “Y” or a delta connected system and are used to…. Provide a relativelylow impedance path to ground, thereby maintaining the system neutral at or near ground potential A grounding transformer or an earthing transformer is used to provide a ground path to either an ungrounded way or a delta-connected system. Uses: It provides a relatively low-impedance path to ground, thereby maintaining the system neutral at or near ground potential. Due to its composition, a zigzag transformer is more effective for grounding purposes because it has less internal winding impedance going to the ground than when using a wye-type transformer. In ungrounded systems, it's still necessary to detect a ground fault. Transformer Star and Star Connections. The voltage between any line of the three-phase transformer is called the “line voltage”, VL, while the voltage between any line and the neutral point of a star connected transformer is called the “phase voltage”, VP.
