SF6 insulated Current Transformers - Type TAG

All Trench Current Transformer designs are based on "head type" construction. CTs are available with either oil or SF6 isolation systems.

Type TAG

Top core current transformer

Identical principle design from 72.5 to 550 kV

SF6 insulation

Composite or Porcelain Insulator

Designed in accordance with main international standards for design, test and construction

Uniformly distributed secondary windings guarantee accurate transformation at both rated and high currents

Low reactance bar type primary conductor provides optimal short-circuit performance

Multiple-turn primaries for small primary currents

Perfect transient response

Core changes after assembly can be carried out without impairing the high voltage insulation
