SF6 insulated Current Transformers – Type SAS

General Features

Explosion proof design with compressible SF₆ insulation system and rupture disc
Excellent seismic performance
Cast aluminuim housing
Excellent short-circuit performance/capability
Optimal field grading accomplished by a fine condenser grading system (from 245 kV)
Special core class ratings TPS, TPX, TPY and TPZ are available
Low reactance bar-type primary permits high short circuit currents
Perfect transient performance
Stable accuracy over a long period of time
Maintenance free
No insulation ageing
Remote supervision of insulation condition by monitoring internal gas density

Type SAS

Top core current transformer
Identical principle design from 72.5 to 800 kV
SF₆ insulation
Composite 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
