PSPI */10kA- overvoltage limiters designed for protecting of high-voltage transmission systems, transformers, switching equipment and HV cable distribution systems against atmospheric and switching overvoltage effects. The functional part of the limiters consists of a column of varistors sized for max. continuous operating voltage UC. The outer insulating shell is made from silicon material (grey colour). The material of the shell shows high resistance to the effects of surface leakage currents and to electric arc, possesses hydrophobic properties and shows excellent resistance to weather effects, pollution and UV radiation. The cover caps, connecting screws, nuts and terminals are made of stainless steel. With their design and technical parameters, the overvoltage limiters of the PSP series conform to the standards EN 60099-4: 2014 and IEC 60099-4: 2014.

Application possibilities

Protection of high-voltage AC networks against lightning and switching surges and fast transients. Suitable for protection of transformers, cables, motors, switchgear, and other high-voltage equipment.

Advantages

• Long protective distance
• High absorption capacity
• Stable U-I characteristics even after repeated discharges
• Resistance to ageing
• Design resistant to explosion and bursting
• Resistance to pollution and UV radiation
• Resistance of the shell to rough handling
• Maintenance-free design
• Resistance to shocks and vibrations
• High mechanical resistance

Transport and storage

The overvoltage limiters may not be exposed to strong shocks and impacts during transport. They should be stored in the long term in an indoor store.

Maintenance

No testing of the function or maintenance such as cleaning is necessary during the anticipated life of the limiter.
