High-voltage applications
High-voltage distribution grids form the backbone of the electricity supply system, transmitting electricity over large distances.
Zelisko transformers for high-voltage applications are completely maintenance-free and are available in dry-type and gas-insulated versions. In addition, Zelisko’s HNP transformers act as phase protection transformers for stator ground fault protection and power transformers. The company’s high-voltage-carrying primary winding is designed as a two-pole winding and cast using a special vacuum pressure process.
