The method proposed by Ancajima et al [16][21] [22] can be viewed as an improvement of the Chowdhuri et al [14] method, as it introduces an important modification in the latter for the calculation of V 0 . The parameter K is computed from [16]:…”

This paper presents a novel method to estimate the parameters of the Disruptive Effect Model for the prediction of the volt-time curves of medium voltage (MV) insulators. Two non-standard impulse voltage waveshapes, of both polarities, were adopted in the tests, namely 1.2 / 10 µs and 7.5 / 30 µs. The measured volt-time characteristics of a 15 kV class pin-type insulator were compared with those predicted by four different procedures related to the Disruptive Effect Model: Darveniza and Vlastos; Hileman; Ancajima et al., and the one proposed in this paper. The results show that the methods by Darveniza and Vlastos and by Hileman do not predict insulator breakdown for the lower peak voltage levels of the 1.2/10 μs waveshape of both polarities. On the other hand, a relative good agreement is found between theoretical and experimental results for the calculations performed using the method proposed in this paper and the one by Ancajima et al.

“…Different methods and models have been proposed: some of them are based on physics of discharge process along the gaps, some others on integration approach and others on simple empirical formulas. The disruptive effect model proposed by Kind [9] on the basis of the work by Witzke and Bliss [10], [11] extended by Darveniza [12], and improved by S Chowdhuri [13], seems to provide satisfactory results for a relatively short gaps (5 cm rod-rod and rod-plane gaps) stressed by standard and non standard lightning impulsive voltages.…”

The paper presents the results of experimental tests performed with impulse voltage with short tail (STLI: 1.2/4 μs) on composite insulators in use in the MV distribution lines and electric traction lines. The voltage-time to breakdown characteristics under 1.2/4 μs waves are presented and compared with the characteristics under standard lightning impulse (LI: 1.2/50 μs). Models based on the disruptive effect, as proposed by Kind [9], and modified by Chowdhuri [13], are also considered and applied in order to predict the Volt-time characteristics under standard and non standard lightning voltages. The viability of the application of these models to the tested insulators is considered and discussed
