INVERSE TIME-OVERCURRENT RELAY USING SUCCESSIVE LINEAR APPROXIMATIONS |
摘要 |
<p>The disclosure relates to a time-overcurrent relay utilizing successive linear time-current segments which approximate a non-linear, inverse time-current curve the linear segments are determined by subtracting a series of ramp like voltages of increasing magnitudes from a series of bias voltages, each of which is of substantially constant magnitude and which bias voltage magnitudes decrease in sequence by the peak magnitude of the preceding ramp voltage.</p> |
