초록

The article deals with the detection of metals in localities of dendrites in internal cavities of porcelain insulators that have been in operation on railway for a long time and exposed to high voltage of DC and AC contact network. The search for dendrites was carried out using a megohmmeter generating high voltage. Research in the vicinity of the detected conducting channels was performed using an electron-probe microanalyzer. Possible mechanisms of dendrite formation are considered.
