Tamperproof-type design to prevent unauthorized operation and ensure stability of Zig-Zag Neutral Grounding Transformers
Primary, secondary and neutral current transformers for precise current monitoring of Neutral Grounding Transformers

Zig-Zag Neutral Grounding Transformers Application Scenarios

Medium & High-Voltage Substations：72.5kV class Neutral Grounding Transformers are core grounding protection devices for urban and industrial substations. They provide stable artificial neutral points for ungrounded systems, connect with arc suppression coils or resistors to limit fault current, and comply with CSA/IEEE standards to ensure the safe operation of large-scale power distribution networks.
Industrial Park Power Grids：For industrial parks with complex loads such as motors, frequency converters and rectifiers, Zig-Zag Neutral Grounding Transformers are ideal for suppressing triplen harmonic currents and balancing phase loads. The neutral grounding transformers with auxiliary winding can also serve as a station power source, meeting the dual needs of grounding protection and on-site power supply for industrial parks.
Renewable Energy Power Generation Systems：In wind farms and photovoltaic power plants connected to the grid, neutral grounding transformers are deployed to handle grid-connected grounding faults, while Zig-Zag Neutral Grounding Transformers are used to solve the problem of three-phase load imbalance caused by unstable new energy output, improving the reliability of grid connection.
Commercial & Residential Distribution Networks：The compact-structured Zig-Zag Neutral Grounding Transformers are suitable for indoor and outdoor distribution stations of commercial plazas and residential communities. The neutral grounding transformers configured with tamperproof design can prevent unauthorized operation, ensuring the stable power supply and grounding safety of end users.
