  • Page 11: Table 1-1. Abb Relays Suitable For Direct Replacement

    BE1-50/51B-219 and BE1-50/51B-226 protective relays are direct replacements for Westinghouse/ABB type CO relays. The BE1-50/51B-219 has a 5 ampere current sensing input. The BE1-50/51B-226 has a 1 ampere current sensing input. Specific relays by catalog number are listed in Table 1-1.

  • Page 12: Current Sensing Input

    The timing accuracy is the sum of ±1 cycle, ±2%. This accuracy applies to the range of 1.3 to 40 times tap and is for a given measured multiple of tap. The measurement of the multiple of tap has an accuracy that is the sum of ±2%, ±25 milliamperes for the BE1-50/51B-219 and ±2%, ±5 milliamperes for the BE1- 50/51B-226.

    Integrating Reset Reset begins when the current drops below 95% of pickup. Integrating reset simulates the disk reset of electromechanical relays. BE1-50/51B-219 and BE1-50/51B-226 relays provide the integrating reset function even when input current falls to zero. Integrating reset characteristics are defined by the following equation and shown in Figure 1-1. Equation constants are provided in Tables 1-2 or 1-3.

  • Page 15: Instantaneous Overcurrent (50) Element

    The instantaneous element in BE1-50/51B-219 and BE1-50/51B-226 relays may be set lower than the instantaneous element in ABB relays and still have the same reach. This is because the BE1-50/51B-219 and BE1-50/51B-226 instantaneous element effectively eliminates the fault current transient overreach components.

    Figure 1-4 shows that a relay set for 1 ampere pickup would pick up at 0.96 amperes with a current containing 40% seventh harmonic. This corresponds to a 10:1 rejection ratio. Other conditions may be evaluated in the same manner. 9252000981 Rev G BE1-50/51B-219/-226 General Information...
