"The IEC, which defines the lightning impulse test methods for electric power equipment, is about to introduce the K-factor method for evaluating overshoot of lightning impulse waveforms," investigators in Yokohama, Japan report.
"There is an urgent need to examine the K-factor method using such parameters as the types and sizes of insulating media and structures. This paper evaluates the K-factor method in the ''High-Voltage Test Techniques'' using the insulation characteristics of overshoot waveforms in non-standard lightning impulse waveforms," wrote S. Okabe and colleagues.
The researchers concluded: "The insulation elements of oil-immersed ...
