Pázmándi Graphical Construction

This page produces the Pázmándi plot of third-harmonic voltages across a synchronous generator. Enter zero-sequence resistances (in ohms) and capacitances (in microfarads).

Zero-Sequence Shunt Resistances (Ohms)

(0 = not connected)

RN (neutral-to-ground)
RO (center-to-ground)
RT (terminal-to-ground)

Include Fault

RF (ohms)
fault location (N = -0.5 to T = +0.5)

Zero-Sequence Shunt Capacitances (uF)

C center (lumped at O)
CT (lumped at T)
