Imagine needing to turn off the power to a 15KV circuit that needs a repair, the switchgear has to isolate the source and ground the circuit so you can make contact and repair. Imagine sitting at a control panel to complete this LOTO (lockout/ Tagout) process in less than 3 minutes. You didn’t even have to put on the sweaty arc flash suit because you can check for the presence of voltage, open the breaker, rack it out, check for the absence of voltage and then ground the circuit and never leave your chair! Since you saved 15-20 minutes time of the process While BOTH de-energizing and RE-energizing, you can go home 40 minutes faster ! THIS is REAL with Switchgear from SRi…
Oh, by the way, you like to see the physical ground before you walk away, don’t bother taking a cover off in the back because you can see the ground switch contact is closed through the window….
