Internal dielectric strength degradation is the main risk affecting the lifetime performance of an instrument transformer. Contributing to 70% of the failures, it can ultimately cause a fire or explosion that can damage nearby high voltage assets. The degradation can be due to overheating, short circuit, oil leakage from gasket deterioration caused by tough environmental conditions, or the humidity contained in oil-impregnated cellulose insulation. An efficient maintenance plan customized to the type and age of the instrument transformers fleet limits its premature aging and reduces the cost of ownership.

Axonai provides a full fleet performance management service to assess, secure and maintain high voltage instrument transformers at high performance.

These services, performed by trained and certified field service engineers allow fast response time and cost-effective service for optimized customer asset availability and life time.
