Protectors against transient overvoltages for analogic, ADSL and ISDN telephone lines with screw, RJ, R&M and Krone type connectors.
Monitor surge events through an impulse counter for discharges on surge protection devices.
Protection against transient overvoltages for coaxial cables with TV, F, BNC, N UHF and 7/16 connectors.
Type 1 protectors against transient overvoltages should be tested with 10/350 µs lightning impulse wave, simulating the effects of direct lightning discharges.
Type 1 + 2 protectors against transient overvoltages should be tested with 10/350 µs lightning impulse wave and 8/20 µs wave, combining the capacity to absorb lightning current with low residual voltage.
