Table 3 Conductivity of the ash collected from the insulators after testing. The ash was diluted in deionized water and the conductivity was corrected for 20 °C

From: Impact of volcanic ash from Cotopaxi-2015 and Tungurahua-2016 eruptions on the dielectric characteristics of suspension insulators, Ecuador

Scenarios

COTOPAXI-2015 conductivity (S/m)

TUNGURAHUA-2016 conductivity (S/m)
