Transformer testing should not end when a value is marked acceptable. Each measurement is a diagnostic clue. When insulation resistance, winding resistance, turns ratio, excitation current, and leakage reactance are interpreted together, they create a clearer picture of transformer health and help engineers energize equipment with confidence. Transformer testing is often viewed as a sequence of individual tasks. In …
As renewable energy continues its rapid expansion, the grid is evolving faster than traditional designs, standards, and maintenance practices can adapt. Inverterbased resources are introducing unfamiliar electrical behaviors that are directly affecting equipment reliability, protection schemes, and testing methods across the industry. Against this backdrop, EPIC26 convenes this October in Fort Worth, Texas, bringing together power professionals to explore how …
The goal of any good power system is simple in theory: Deliver clean power to the loads it serves. In practice, however, “clean” quickly becomes a relative term. Spend enough time around power quality measurements, and one thing becomes apparent: Many of the disturbances blamed on incoming utility power originate inside the facility itself. Wiring practices, grounding methods, and interconnected …

Verifying the integrity of power cable insulation is an essential step to ensure the reliability and safety of electrical systems. Applied-voltage tests are widely used before commissioning new cables and during maintenance and diagnostic activities throughout their service life. These tests enable identification of insulation defects, dielectric degradation, or installation issues that could lead to operational failures, supply interruptions, or …
Fall-of-potential (FOP) testing is widely regarded as one of the most reliable methods for evaluating grounding system performance. Under ideal conditions, the procedure is straightforward: Electrodes are driven into the soil at prescribed intervals, measurements are recorded, and resistance values are calculated with a high degree of confidence. In practice, however, technicians often encounter less-than-ideal environments. Urban and industrial sites …
This paper analyzes the ground differential or restricted earth fault (REF) element for transformer protection and compares its performance against various levels of current transformer (CT) error and saturation. An empirical analysis was performed to determine the limits of today’s common digital relays as they experience CT errors. This can help engineers develop general guidelines for designing protection systems related …
I have spent many months researching how, as an equipment insurer, to enhance our understanding of underwriting risk by improving the assessment of electrical risk at medium- and high-voltage facilities through predictive analytics. The answer I found was partial discharge (PD) testing that uses touchless acoustical methods with intrinsic AI capability. Partial discharge is a localized voltage discharge within an …
