electricpy.fault.trvresistor(C, L, reduction, Rd0=500, wd0=260000.0, tpk0=1e-05)[source]¶

Transient Recovery Voltage (TRV) Reduction Resistor Function.

Function to find the resistor value that will reduce the TRV by a specified percentage.

Parameters:¶

C : float¶

Capacitance Value in Farads.

L : float¶

Inductance in Henries.

reduction : float¶

The percentage that the TRV should be reduced by.

Rd0 : float, optional¶

Damping Resistor Evaluation Starting Point, default=500

wd0 : float, optional¶

Omega-d evaluation starting point, default=260*k

tpk0 : float, optional¶

Time of peak voltage evaluation starting point, default=10*u

Returns:¶

• Rd (float) – Damping resistor value, in ohms.

• wd (float) – Omega-d

• tpk (float) – Time of peak voltage.
