1. Improve power supply reliability

When a single-phase grounding fault occurs in a neutral point ungrounded system, although the line voltage triangle remains symmetrical and the system can continue to supply power for some time, the capacitive current to the ground may be large at this time, which can easily cause intermittent arcs, resulting in equipment damage and power outages. The grounding transformer provides an artificial neutral point, so that the system can adopt arc suppression coil or low resistance grounding method, effectively reducing the capacitive current to the ground during ground short circuit fault and improving the reliability of power supply.

2. Protect equipment and personnel safety

, through its special design, can release the current to the earth through the grounding wire, effectively avoiding the voltage rise and equipment damage caused by charge accumulation. At the same time, in abnormal conditions such as lightning, the grounding transformer can also release high-energy electromagnetic waves such as lightning through the grounding wire to protect the equipment from lightning damage.

3. Meet specific system requirements

In some special application scenarios, such as converting a three-wire, ungrounded circuit to a four-wire, grounded circuit, or supplying power to secondary network loads and other non-network line-to-ground connected loads, the grounding transformer also plays an irreplaceable role. In addition, in distributed power generation systems, grounding transformers can also prevent overvoltage in the case of feedback electricity, protecting the safe operation of generators and power grids.

4. Optimize system performance

The grounding transformer also has the working characteristics of low zero-sequence impedance, high excitation impedance, and low no-load loss. These characteristics enable the grounding transformer to provide effective grounding while reducing the no-load current and energy consumption of the system and improving the overall performance of the system.
