⚡ IEEE C57.19.00 / Doble (Bushing Tan Delta Power Factor % & C1/C2 Capacitance pF)

Transformer Bushing Tan Delta Calculator

Analyze 10 kV dielectric power factor (Tan Delta %) and capacitance (C1 main insulation / C2 tap insulation) for high-voltage oil-impregnated paper (OIP) and resin-impregnated synthetics (RIS) transformer bushings under IEEE C57.19.00: evaluate insulation degradation (flagging Tan Delta rise >0.5% or capacitance shift >5% indicating moisture or partial breakdown), and NETA testing profits.
