IEEE PC37.112 DRAFT 2017 Edition, July 1, 2017 Draft Standard for Inverse-Time Characteristics Equations for Overcurrent Relays
More info
Description / Abstract:
The scope of this standard includes the review of various existing analytic techniques used to represent relay operating characteristic curve shapes and proposes analytical (formula) representation of typical operating characteristic curve shapes to foster some standardization of available inverse-time relay characteristics provided in microprocessor or computer relay applications.
Purpose
The purpose of this standard is to provide an analytic (formula) representation of typical relay operating characteristic curve shapes of various inverse-time relays to facilitate representation by microprocessor-type relays and promote a degree of standardization in the inverse shape of a selected curve.
