5 m) #14 leads connected to the relay. The relay setting was determined by considering the maximum external fault of 50 000 A and the ct of the faulted breaker completely saturated. 6 V. 110-1996 applied for asymmetry and errors, giving a calculated value of 337 V. The nearest setting of the relay used is 400 V at 2210 W. 110-1996 This case was analyzed using the two breaker model, as in Þgure 23. Figure 23ÑEquivalent circuit of 3 cts supplying current to 1 ct The model uses an equivalent C800, 3000:5 ct to represent the three unfaulted breaker cts while the external fault was applied to the fourth breaker.

2 Saturation effects on static relays Static relays fall into two main categoriesÑthose relays that use an analog of the input current for processing the signal, and those relays in which analog to digital converters are used. Analog type relays respond to the average, not the rms, value of current. The response of digital relays is a function of the operation of the relay software. For a given waveshape, the difference can be compensated for, but a universal correction is not practical. This difference should be considered particularly when applying both electromechanical and static relays in a coordinated scheme.

For external faults, the ct on the faulted circuit is assumed to saturate completely (worst possibility). The relay sees a voltage equal to the external fault current multiplied by the ct ratio times the resistance of the leads and the secondary winding of the saturated ct. If this voltage is less than the voltage setting of the relay, then the relay will not operate. For an internal fault, the cts attempt to force secondary current through the high-impedance differential relay and a relatively high voltage is developed to operate the overvoltage unit.
