Solutions for Energy technology

Energy technology

You know the situation: complex production systems, high requirements in terms of the quality, delivery time and reliability, permanent cost pressure. This requires more than ever a comprehensive operational readiness in order to be able to maintain and improve the competitiveness at the international level. In practice, however, a comprehensive operational readiness is often given only conditionally, because insulation faults may slowly but progressively occur due to ageing, moisture, pollution, mechanical damage and other factors. Consequences of such undiscovered errors are costly plant shut-downs and operational downtime, repair costs and usually high costs resulting from production downtime. In the worst case these insulation faults are even a frequent cause of fires and personal injuries.
