... TISP70xxF3 (LV) Overvoltage Protector Series Deployment These devices are three terminal overvoltage protectors. They limit the voltage between three points in the circuit. Typically, this would be the two line conductors and protective ground (Figure 17). In Figure 17, protective functions Th2 and Th3 limit the maximum voltage between each conductor and ground to their respective ±V (BO) values. Protective function Th1 limits the maximum voltage between the two conductors to its ± ...

Virtual voltage rise times are given by straight line extrapolation through the 30 % and 90 % points of the voltage waveform to zero and 100 %. Mathematically, this is equivalent to 3.24 times the time constant, which gives 3. 9.73 which is rounded to 10 µ ...

TISP70xxF3 (LV) Overvoltage Protector Series Lightning Surge (continued) 1.2/50 Generators (continued) Impulse Testing To verify the withstand capability and safety of the equipment, standards require that the equipment is tested with various impulse wave forms. The table in this section shows some common test values. Manufacturers are being increasingly required to design in protection coordination. This means that each protector is operated at its design level and currents are diverted through the appropriate protector, e ...

... TISP70xxF3 (LV) Overvoltage Protector Series Protection Voltage The protection voltage, (V (BO) ), increases under lightning surge conditions due to thyristor regeneration. This increase is dependent on the rate of current rise, di/dt, when the TISP be estimated by multiplying the 50 Hz rate V (BO) (250 V/ms) value by the normalized increase at the surge’s di/dt. An estimate of the di/dt can be made from the surge generator voltage rate of rise, dv/dt, and the circuit resistance example, the ITU-T recommendation K.21 1.5 kV, 10/700 surge has an average dv/dt of 150 V/µ ...
