Description

Dry-type Grounding Transformer product Introduction

Dry-type Grounding Transformer and renewable energy Grounding Transformer provide reliable grounding paths for unbalanced load and fault currents in ungrounded systems.

These transformers typically adopt two configurations: Zig-Zag (Zn) (with/without auxiliary winding) or Wye (Ynd) with delta secondary. The cost-effective, compact Zig-Zag connection is preferred for both Dry-type Grounding Transformer and renewable energy Grounding Transformer.

For enhanced safety, neutral ground resistors (NGR) are paired with Dry-type Grounding Transformer and renewable energy Grounding Transformer to limit fault current. NGR voltage, current rating and duration must match the parameters of the Dry-type Grounding Transformer, and the current rating should exceed cable charging and transformer magnetizing current.

Renewable energy Grounding Transformer Features

Tailored for Renewable Energy Scenarios：This renewable energy Grounding Transformer is engineered specifically for wind, solar, and other renewable power systems, providing stable artificial neutral points for ungrounded grids. Unlike the Dry-type Grounding Transformer that relies on oil insulation, its dry-type structure eliminates oil leakage risks, making it more suitable for eco-sensitive renewable energy stations.
Wide Voltage Compatibility：Covering 27kV, 33kV, 34.5kV, and 35kV voltage grades, the renewable energy Grounding Transformer flexibly adapts to diverse regional grid standards of renewable projects. Compared with the Dry-type Grounding Transformer, it features a more compact size, which saves installation space in distributed photovoltaic and wind power plants.
High Safety & Low Maintenance：The dry-type design of this renewable energy Grounding Transformer ensures excellent fire resistance, avoiding the potential fire hazards associated with the Dry-type Grounding Transformer in high-temperature environments. It requires no regular oil quality testing or replacement, significantly reducing the maintenance workload compared with the Oil-immersed Grounding Transformer.
Strong Synergy with Grid Equipment：This renewable energy Grounding Transformer supports multiple grounding configurations, and can work in coordination with the Dry-type Grounding Transformer in hybrid power grids that combine renewable and traditional energy sources. It effectively limits fault currents and transient overvoltages, safeguarding the stable operation of the entire power system.
