Peak Transient Recovery Function.

Peak Transient Recovery Voltage calculation function, evaluates the peak transient recovery voltage (restriking voltage) and the Rate-of-Rise-Recovery Voltage.

Parameters:

  • C (float) – Capacitance Value in Farads.

  • L (float) – Inductance in Henries.

  • R (float, optional) – The resistance of the system used for calculation, default=0.

  • VLL (float, exclusive) – Line-to-Line voltage, exclusive optional argument.

  • VLN (float, exclusive) – Line-to-Neutral voltage, exclusive optional argument.

  • freq (float, optional) – System frequency in Hz.

Returns:

  • Vcpk (float) – Peak Transient Recovery Voltage in volts.

  • RRRV (float) – The RRRV (Rate-of-Rise-Recovery Voltage) calculated given the parameters in volts per second.
