Single Phase Transformer and Loading Resistor has a Neutral which is available, a single phase distribution transformer can be used in conjunction with a loading resistor, to provide high resistance grounding. Lachhman Electronics manufactures Single Phase Transformer and Loading Resistor.
Lachhman Electronics also manufactures wide range of power resistors, neutral grounding resistors and a wide range of electrical control panels. Single Phase Transformer and Loading Resistor is particularly well suited for grounding of generators, in that it allows the system to operate like an ungrounded system under normal conditions, while still retaining the ability to limit fault currents during a fault. Figure 1 shows a typical schematic. The primary of the transformer is connected from the system neutral to ground. The loading resistor is connected across the transformer secondary.
