PTG lightning current and surge arrester can achieve energy coordination with other PTG SPD without decoupling device. Widely used in wind power system, low-voltage equipment of constructions, AC side of PV power system, telecom base station, generators, etc., greatly improving the reliability and safety of electrical equipment.

PE... 25W1-10R series uses PTG patented technology to achieve excellent performance with high continuous operating voltage, no follow current, low voltage protection level, etc., it equips with unique thermo disconnect device, visual and remote status indication. 

PTE 320 Series T1+T2 SPDs are designed by exclusive invention patent technology, with large lightning current discharge capacity (I_imp : 100kA , 10/350 µs) and no follow current, can directly protect the terminal equipment and other features, which represents the world leading technology. This series is now the most compact design (18 mm per phase only); the thermo disconnect device is series connection in the main circuit (instead of traditional bypass circuit solution), which ensures the high reliability and low risk of the equipment. Its visual and remote status indication provides real-time online status monitoring; its no follow current technology ensures the high reliability of the power grid system.

PTG lightning current and surge arrester is usually installed in LPZ 0_B-2.
