METHODS OF RESTORING INSULATION HIGH VOLTAGE CABLES
The article considers the main causes of occurrence of partial discharges in cables and deterioration of their electrical strength. Such causes are voids and condensate in the insulation of cables, the conditions for their laying and storage. Authors performed analysis of influence of weather conditions on formation of condensate in cables leading to formation of partial discharges. Authors also proposed a method of restoring cable insulation to reduce partial discharges in cable lines.
