    INTRODUCTION BE1-50/51B-214/-215/-223/-225 protective relays are direct replacements for General Electric, IAC relays. The BE1-50/51B-214/-215/-223 has a 5 ampere current sensing input. The BE1-50/51B-225 has a 1 ampere current sensing input. Compatible IAC model numbers are listed in Table 1-1. Table 1-1. GE IAC Relays Suitable For Direct Replacement...

    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-214/-215/-223 and ±2%, ±5 milliamperes for the BE1-50/51B-225.

    Integrating Reset Reset begins when the current drops below 95% of pickup. Integrating reset simulates the disk reset of electromechanical relays. BE1-50/51B-214/-215/-223/-225 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.

    Section 2 illustrates the location of SW3. The instantaneous element in BE1-50/51B-214/-215/-223/-225 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-214/- 215/-223/-225 instantaneous element effectively eliminates the fault current transient overreach components.

  • Page 51: 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-214/-215/-223/-225 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 This relay scheme allows each unit to be withdrawn one at a time for testing purposes without losing protection.
