Transformer Explosion Breaking News |
Excessive moisture and other impurities in the paper and oil can significantly reduce the dielectric strength and the partial discharge inception levels; therefore, it has a profound effect on the aging rate.

and adversely affecting the tensile strength and dielectric properties of the insulation. The result can be catastrophic, ending in premature failure, with replacement involving a considerable amount of time and expense – vital assets that you cannot afford to waste.
Yet, power utilities across the globe are faced with reductions of capital spending, retirement of experienced personnel, and crippled maintenance budgets. Existing resources must be leveraged to get the most out of assets that are nearing the end of their useful life.
Meeting the growing demands of the grid, while maintaining system reliability with this aging fleet is extremely taxing and uneconomical. Without significant changes in the way the utility operates and cares for its transformers, resources will be lost at exponential rates, but traditional maintenance is reactive rather than proactive.

OLT Testers by KEP
The OLT Insulating liquid testers by KEP are designed for measuring the oil dielectric breakdown voltage; the A-Series oil testers are fully automatic, produce accurate testing results, safe for the operator, and comply with the industry’s main standards.The OLT insulating liquid test sets switch off the voltage feed to the electrodes immediately after the testing is over, which allows for testing dielectric liquids susceptible to disintegration due to arcing caused by a breakdown.
Main features of the KEP oil testers OLT A-Series:
