Manage Transformer Failure Risks - Efficient Plant

Keeping Transformers Healthy Is Key to Electrical-system Reliability.Paper, The Weakest LinkThe Issue of GasLife ExtensionPreventive-Maintenance PlansGetting transformer experts to agree can be especially difficult, according to Alan M. Ross of Tallmadge, OH-based S.D. Myers Inc. (sdmyers.com). On some points, however, they sing the same song: • Most will acknowledge that not all transformer failuresare alike. • They’ll also agree that the insulation or paper is the primary limiting factor in transformer life. Although industrial operations typically use power to produce something of value, risks associated with the loss of that power can be misunderstood and, frequently, ignored. Risk, though, comes in many different forms. In the case of transformers, the insurance industry typically quantifies the risk of failure as the cost to replace the equipment. Yet, as Ross noted, the loss of production capacity, i.e.,business interruption, is usually much higher than the cost of transformer replacement. He offered the following advice for managing such risks, starting with why transformers fail in the first place.Get price
