Abstract

Firstly

the simulation of steady-state secondary current under different degree of saturation is implemented in this paper. Then

according to the common algorithms of microprocessor-based protection

the discrete sampling process is simulated

and the sampling value of secondary current is calculated. Based on the simulation results

TA steady-state saturated characteristics are analyzed

and TA saturation influence on over-current protection are discussed. Lastly

this paper proposes that when TA is saturated

the selection of suitable sampling frequency and setting value based on saturation factor can make sure the protection operates correctly.
