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.
Ring Core Current Transformer for Power Transformers
These special Ring Core Current Transformers are intended for use in high-power transformers. The Current Transformers are characterized by their increased temperature and oil resistance and can be used for decades without any maintenance.
