Type 1 protectors against transient overvoltages should be tested with 10/350 µs lightning impulse wave, simulating the effects of direct lightning discharges.
The Power Lines Tester monitors the following characteristics for critical lines: Voltage between phases and neutral, Working frequency and Ground-Neutral Loop Impedance
Type 2 protectors against transient overvoltages should be tested with 8/20 µs current impulse wave, simulating lightning secondary effects.
Protectors against transient overvoltages for analogic, ADSL and ISDN telephone lines with screw, RJ, R&M and Krone type connectors.
Type 2 + 3 protectors against transient overvoltages should be tested with 8/20 µs current impulse wave and a combination impulse wave, leaving low residual voltages.
