Dielectric Strength Test: How IEC 60243-1 Measures Breakdown in Solid Insulation
A dielectric strength test pushes a sample of solid insulation to failure with power-frequency AC. You record the voltage where it punctures. You divide by the thickness. You get a number in kV/mm. That number shows up on most datasheets for plastics, laminates, papers, films, and elastomers. It looks simple. It isn’t. The same material can give very… Read More: Dielectric Strength Test: How IEC 60243-1 Measures Breakdown in Solid… »
