| Abstract: | The calculation of reference value for quick break protection of computer controlling motor was introduced.The formulas for calculating protective reference value were given:(1) in the case of positive current and total current with time delay, the formula was I dz = k k k j I qd / Ne ;(2)in the case of total current without time delay, the formula was I dz = k d k k k j I qd / Ne . The properties of computer controlling transformer overcurrent protection were analyzed, the methods for calculating overcurrent reference value were given. The sensitivity correction was done and a calculating example for computer controlling transformer overcurrent protection was presented. |
