    IAC relays. BE1-50/51B-218 and BE1-50/51B-228 protective relays are enclosed in an S1 case. The BE1-50/51B-218 has a 5 ampere current sensing input. The BE1-50/51B-228 has a 1 ampere current sensing input. Compatible IAC model numbers 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-218 and ±2%, ±5 milliamperes for the BE1- 50/51B-228.

    Integrating Reset Reset begins when the current drops below 95% of pickup. Integrating reset simulates the disk reset of electromechanical relays. BE1-50/51B-218 and BE1-50/51B-228 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-218 and BE1-50/51B-228 relays may be set lower than the instantaneous element in IAC relays and still have the same reach. This is because the BE1-50/51B-218 and BE1-50/51B-228 instantaneous element effectively eliminates the fault current transient overreach components.

  • Page 49: Setting The Relay

    All relays should be tested periodically to identify and correct any problems that are found. Single phase relays such as the BE1-50/51B-218 and BE1-50/51B-228 are normally used in groups of four (three phase and ground) on the protected circuit. This relay scheme allows each unit to be withdrawn one at a time for testing purposes without losing protection.
