electricpy.fault.genlossfield(Xd, Xpd, Zbase=1, CTR=1, VTR=1)[source]¶

Electric Generator Loss of Field Function.

Generates the Loss-of-Field Element settings for a generator using the Xd value and per-unit base information.

Parameters:¶

Xd : float¶

The Transient Reactance (Xd) term. May be specified in ohms or Per-Unit ohms if Zbase is set.

Xpd : float¶

The Sub-Transient Reactance (X’d) term. May be specified in ohms or Per-Unit ohms if Zbase is set.

Zbase : float, optional¶

Base impedance, used to convert per-unit Xd and Xpd to secondary values. default=1

CTR : float, optional¶

Current Transformer Ratio, default=1

VTR : float, optional¶

Voltage Transformer Ratio, default=1

Returns:¶

• ZoneOff (float) – Zone Offset in ohms.

• Z1dia (float) – Zone 1 diameter in ohms.

• Z2dia (float) – Zone 2 diameter in ohms.
