IEEE C37.112-1996
IEEE Standard Inverse-Time Characteristic Equations for Overcurrent Relays



Number:
IEEE C37.112-1996
Standard:
IEEE Standard Inverse-Time Characteristic Equations for Overcurrent Relays
Year:
1996
Brief Description:

The inverse-time characteristics of overcurrent relays are defined in this standard. Operating equations and allowances are provided in the standard. The standard defines an integral equation for microprocessor relays that ensures coordination not only in the case of constant current input but for any current condition of varying magnitude. Electromechanical inverse-time overcurrent relay reset characteristics are defined in the event that designers of microprocessor based relays and computer relays want to match the reset characteristics of the electromechanical relays.
