IntelliRupter® PulseCloser® Fault Interrupter Installation

See the easy-up installation of an Intellirupter® PulseCloser® Fault Interrupter with Ameren Missouri. PulseClosing is the first major innovation in recloser technology in 70 years.

Very good and interesting video regarding ensuring safety and compliance

Most efficient device since the invention of reclosing in the 1930s as well as limit customer outages from faults.

This device is one of a few that Ameren installs on a 12 kV line. The idea is these operate together in the event of a fault, rerouting power to keep about 2/3 of the affected customers on that would’ve normally been lost. Dunno how much luck utilities have with these, I notice Ameren will install this, then come back and close it in later. The bypass switches at the top remain closed in the meantime

[@luket6405]

do the original connections across the line stay connected like that or does the power get routed through the interrupter?

[@1949lab]

Did you guys determine which side of breaker was source and load side before installation?

I noticed on there Personal protective equipment,they weren't wearing sleeves,only insulated gloves.

John k - read OSHA 1910.269(l)(4)(i)

[@smv133]

some of those connections look pretty sloppy.

[@vincentparent2781]

you don't want to crush wires

[@Jinguapingi]

Actually, this fault interrupter is useless. You have to open the original fuses or cut the wires, but this is not shown.

I was looking for the same thing, I follow this stuff but I dont work in the field but understand basic concepts.

Frankvidi This installation video only seems to show how to hang, connect, and get the interruptor ready for service. Not actually closing it and putting it into service. You will note the green 0s at the bottom of the interrupter at the end of the video which I believe signifies that the interruptor is open. Hence why the switches are closed.

[@lukezarakas3549]

You must not understand how the distribution system works very well, especially circuit interruption. There are on-board switches outside of the internal vacuum switches allowing you can have a visual open for isolating downstream equipment. The vacuum switches provide the interruption and the external solid rocker switches provide visual isolation. Nothing about the intellirupter is useless.

@@lukezarakas3549 We understand with this new fancy "protective safety device" bypassed with "one-shot thermal protective devices" it is no more than an expensive fancy pole ornament or bird perch.
This is what Frankvidi means and says. :-)

Também pensei a mesma coisa, trabalho com Linha viva o Brasil à 10 anos, e deveriam abrir a chave faca.
