25.8kV 27kV 33kV 600A Neutral Zig-zag Grounding Reactor Transformer

Product Introduction
The 33kV 600A Neutral Zig-zag Grounding Reactor Transformer is a high-performance grounding solution designed to meet the strict requirements of IEC 60076-1, IEC 60076-5, IEC 60076-20, and GB/T 1094.6 standards, with oil quality tested according to ASTM D6871. This grounding transformer is engineered to provide effective neutral grounding, enhanced system stability, and fault current limitation in medium- and high-voltage networks. With a primary voltage of 33kV and 11432.0kVA rating, the transformer supports 100A power rating for 10 seconds, making it ideal for system grounding applications in substations, industrial facilities, and renewable energy projects. The ONAN cooling method provides efficient heat dissipation for continuous operation, while the use of high-grade mineral insulating oil ensures long-term performance and compliance with international safety standards.

Manufacturer Test

NPC Electirc manufacture Grounding transformers have the strict quality control,The Progress Test for Grounding transformers is carried out during the manufacturing process to ensure that the transformer meets all design and quality requirements. These tests include verification of the core insulation, winding resistance, and dielectric strength of the transformer. Additionally, electrical components such as bushings, tap changers, and protection devices are tested for proper functionality. The progress test also checks the transformer’s ability to handle operational loads and voltage fluctuations. Any issues identified during these tests are addressed before moving on to the final testing stages, ensuring that the transformer is reliable, safe, and ready for commissioning. These tests are essential to confirm the transformer’s performance under real-world conditions and compliance with industry standards.
