36kV 38kV ONAN/KNAN Oil immersed Grounding Transformer

Earthing Transformers

Key Product Features

• Diversified Grounding Configurations：Our industrial earthing transformers and Oil immersed Grounding Transformer are available in multiple grounding configurations to match diverse grid demands:

Solidly Grounded: Provides a low-impedance path for fault currents to the ground, with the Oil immersed Grounding Transformer excelling in high-stability scenarios.

Resistor Grounded: Includes a series resistor to limit fault currents and reduce stress on the power system during a fault, ideal for industrial earthing transformers applied in heavy-duty industrial grids.

Reactance Grounded: Incorporates a reactor in series with the neutral grounding, balancing fault current limitation and system stability, a core advantage of the Oil immersed Grounding Transformer.

• Zigzag Grounding: Special winding configuration for low-impedance zero-sequence current paths, tailored for industrial earthing transformers in complex substation systems.
• Tailored for Different Voltage Systems：Both industrial earthing transformers and Oil immersed Grounding Transformer are designed to meet the specific requirements of various voltage systems and substations, ensuring optimal performance across diverse applications. The Oil immersed Grounding Transformer, in particular, is optimized for medium-to-high voltage grids, adapting seamlessly to regional power system standards.
• Enhanced System Safety：The Oil immersed Grounding Transformer provides a low-impedance path for fault currents, minimizing the risk of high voltages during ground faults. Meanwhile, industrial earthing transformers are engineered to prevent electrical shocks and minimize equipment damage, together enhancing the overall safety of power systems.
• Fault Current Limitation：Industrial earthing transformers effectively limit fault currents during ground faults, safeguarding equipment from thermal and mechanical stress. The Oil immersed Grounding Transformer further enables proper fault detection and ensures quick isolation, maintaining critical system stability during grid anomalies.
• Flexible Neutral Grounding Methods：The design of industrial earthing transformers and Oil immersed Grounding Transformer accommodates different neutral grounding methods, including solid grounding, resistance grounding, and reactance grounding. These products adapt to varying fault current levels, system requirements, and operational considerations, with the Oil immersed Grounding Transformer offering superior adaptability for harsh working conditions.
• Robust Construction：Vziman industrial earthing transformers are built to withstand harsh environmental conditions, ensuring long-term reliable performance. Both product series simplify installation and maintenance, with the Oil immersed Grounding Transformer boasting enhanced corrosion resistance and heat dissipation, providing a durable solution for substation grounding.
