The protection voltage, (V
the rate of current rise, di/dt, when the TISP
tions can be estimated by multiplying the 50 Hz rate V
estimate of the di/dt can be made from the surge generator voltage rate of rise, dv/dt, and the circuit resistance.
As an example, the ITU-T K.21 1.5 kV, 10/700 µs surge has an average dv/dt of 150 V/µs, but, as the rise is exponential, the initial dv/dt
is higher, being in the region of 450 V/µs. The instantaneous generator output resistance is 25 Ω. If the equipment has an additional
series resistance of 20 Ω, the total series resistance becomes 45 Ω. The maximum di/dt then can be estimated as 450/45 = 10 A/µs. In
practice, the measured di/dt and protection voltage increase will be lower due to inductive effects and the finite slope resistance of the
