Working Principle of 100 kVA Oil Immersed Earthing Transformer 3 Phase Transformer
The 100 kVA Oil Immersed Earthing Transformer 3 Phase Transformer operates by creating an artificial neutral point in three-phase systems where a neutral is not naturally available. When connected to ground-often together with a resistor or reactor-it allows earth fault currents to flow in a controlled manner.
This controlled grounding method helps to:
- Limit transient overvoltage during earth faults
- Enable protective relays to detect and isolate faults quickly
- Reduce damage to cables, generators, and switchgear
The oil-immersed insulation system ensures stable dielectric strength and efficient heat dissipation, allowing the transformer to operate continuously under grounding duty conditions.
Key Advantages of 100 kVA Oil Immersed Earthing Transformer 3 Phase Transformer
Reliable Oil-Immersed Insulation System
Transformer oil provides excellent insulation and cooling, ensuring long-term electrical stability and reduced thermal stress during fault conditions.
Stable Three-Phase Grounding Performance
Designed specifically for grounding applications, the transformer delivers balanced and predictable performance during single-line-to-ground faults.
High Mechanical and Electrical Durability
The sealed tank structure protects internal components from moisture, dust, and environmental influence, making it suitable for outdoor or substation installation.
Customizable Grounding Configuration
Impedance value, voltage level, and enclosure design can be tailored to match different grounding philosophies and grid requirements.
