electricpy.fault.protectiontap(S, CTR=1, VLN=None, VLL=None)[source]¶

Protection TAP Setting Calculator.

Evaluates the required TAP setting based on the rated power of a transformer (the object being protected) and the voltage (either primary or secondary) in conjunction with the CTR (current transformer ratio) for the side in question (primary/ secondary).

Parameters:¶

CTR : float¶

The Current Transformer Ratio.

S : float¶

Rated apparent power magnitude (VA/VAR/W).

VLN : float, exclusive¶

Line-to-Neutral voltage in volts.

VLL : float, exclusive¶

Line-to-Line voltage in volts.

Returns:¶

TAP – The TAP setting required to meet the specifications.

Return type:¶
