The choice of using either switchgear or switchboards must be based on many different criteria and the design of the power system requires thought be given to each one. Following are insights into just a few of the differences to help in making those decisions. |

GE’s zone selective interlocking with instantaneous protection (I-ZSI) has been developed to provide safety and selectivity at the same time, all the time. Zone selective interlocking schemes are limited to circuit breakers that are a short distance of each other. Selectivity between a circuit breaker and its downstream current limiting device without control signal connections between the two have also been developed. GEs waveform recognition (WFR) algorithm extends the zone of selectivity from the low voltage switchgear down to the low voltage MCCs, panelboards and any other equipment and at the same time reduces the arc flash energy at this equipment to a low level. This feature has no distance limitation. |
