Assess the condition of your critical transformers with testing and monitoring solutions by Monitra

Insulation Defects in Both Oil-Filled and Dry-Type Transformers

Transformers are amongst the most operation-critical assets on any HV site, and keeping them in good condition is vital.

In oil-filled transformers, gas bubbles in the oil, voids or gaps in the paper or pressboard insulation and high voltage partial discharge in the bushings and tap-changers can all contribute to the failure of the transformer. In dry-type transformers, surface tracking and voids in the insulation are the most common causes of problems in transformer insulation.

At Monitra, we have a range of testing and monitoring solutions that can help to detect the development of underlying defects and assess the insulation condition of your transformers, increasing safety and avoiding unplanned outages.
