MAIN FEATURES
Conventional Fluid Insulated ASCs:
a safe reliable and proven solution for 50 years
Reliable Power Supply
The use of an Arc Suppression Coil provides continuous power supply in the event of an earth fault using continuous current regulation, which allows accurate tuning and minimizes residual current.
Proven Design
With over 50 years of experience in the manufacturing of Arc Suppression Coils using Trench's well-proven and worldwide established design.
Improved operational safety
The Arc Suppression Coil limits the touch voltages in the system caused by earth faults, increasing people's safety and the protection of the equipment.
Compact Construction
Optimize design by leveraging experience and standardizing products for each market.
Modular design
Offers flexibility in selecting different components to suit the customer's requirements or specific product design needs.
Flexible adjustment
Stepless adjustable design, ranging from 10-100% of rated current by precise adjustment of the plunger core using a motor-drive-unit.
Control
Manual control or automatic tuning to the current network status using a Trench Austria earth fault compensation controller.
Special design
A Trench Arc Suppression Coil with a built-in earthing transformer, the “Neutral Earthing Aggregate”.
PRODUCT APPLICATIONS

Arc Suppression Coils
ASCs mitigate the effects of single-phase earth faults, the most common type of fault in an electrical distribution network. Fully adjustable Arc Suppression Coils enable optimum efficiency of the resonant earthing technology.
