ANSI/NETA Standard for Acceptance Testing Specifications for Electrical Power . Specifications have been published in , , , , and Portage, Mich.-based InterNational Electrical Testing Association (NETA) recently published ANSI/NETA MTS, “Standard for Maintenance. PREFACE (continued). ANSI/NETA MTS Optional Tests. The purpose of these specifications is to assure that all tested electrical equipment and systems.

ANSI/NETA MTS REQUIRED? – Electric power & transmission & distribution – Eng-Tips
Without validating that arcing time also remains acceptable, I fail to see how the arc flash study can be validated. That’s just an opinion, you understand. The scary part, though, is that I have been in the electrical testing biz since and had a NETA Level IV certification before changing to the present job.
It did not tell me the condition of system protection devices and their ability to sense and properly react to overcurrent conditions. Also the will be seperate task tables with different HRC’s for properly maintained equipment.
Whoever does the arc-flash study should recommend maintenance testing of the protective devices as part of their annsi-neta. Once you open that breaker and rack it out you have broken loose dried lubricants, excercised springs, etc.
Disabling the trip unit and turning the local breaker into a switch controlled by a protective relay was a good solution in that situation. Others have the electro-thermo-mechanical devices. Have them put that in their pipe and smoke it He may have to travel with said trailer for several hundred miles to my site in Armpit, Mississippi, for which I pay, annsi-neta when he gets there, he’s pulling out the ONLY breaker feeding my station, so I’m off-line on an interstate pipeline, for a scheduled outage, all the while hoping that something doesn’t get broken by that remove-test-replace cycle.
By ansl-neta you are opting in to receive e-mail. We have tried an optional solution for some of these “problem” breakers, that uses the installation of CT’s and a protective relay.
Are you an Engineering professional? There are many ways to catpure this data, this device is new and perhaps the most simple way to do it.
Zogzog- I first used a first-trip device when working with a large southern utility company.

Hard to reach bolts in areas mhs-2007 poor access done ansi-nta people trying to hurry working an odd hour shift certainly seems to increase the potential for problems, add to that that unfortunately some people working in the industry, at least in my recent experience, don’t seem as diligent as I thought we were in the past.

It’s easy to join and it’s free. Arc flash is concerned with the interruption time ansi-netw includes the arcing time within the interrupter. I have a customer in my area struggling with many of the same issues described in the post, there are several molded case breakers, larger frames with very compact buswork installation that on a few occasions has resulted in problems after testing.
If on the other hand ansi-ndta response is “Well, we’ve never needed this before Perfect tool for validation of an arc flash study though.

It did indeed point out some issues with transmission and distribution breakers. Red Flag This Post Please let us know here why this post is inappropriate. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Some were pretty hard opposed to the idea, some greatly in favor, and from a long term standpoint I guess we’ll see as we only started doing this a year ago.
I’m working on this. Anwi-neta have to bring in a contractor with a test set that is towed in on a trailer. It’s only as good as the technician on YOUR job. Maintenance, tests, and inspections shall be documented. For additional direction for performing maintenance on overcurrent protective devices, see Chapter 2, Safety-Related Maintenance Requirements.

It is a very good tool, and I recommended it to several clients after I went back into power system field services. Outside those areas, you’re going to be paying for expenses and mileage in addition to personnel cost and test equipment cost.
Close this window and log in. There has never been an Electrical Maintenance Program since this company was first formed. I think you are basically mts-0207.
The arc-flash study is supposed to consider the “condition of maintenance” of the equipment. The second variety can only be really tested by putting large and very inconvenient amounts of current through them. Ah, the prospects of retirement I manage the electrical side of things for thirty-odd natural gas compression facilities, mts2007 of which have volt equipment dating back to the early ‘s. Lastly, and this pains me to say, a lot of the ‘test technicians’ who perform this work nts-2007 not be as capable as wed like them to be.
So if that happens, ans-ineta 1 from the OSHA inspector is “What is the nature of your electrical safety program? Unbolting twelve bolts ansi-heta the bus side connection and disconnecting twelve thumb-sized cables on the load side so that the break can be tested is a problem. Students Click Here Join Us! The arc-flash calculations assume that the upstream devices are going to operate.
I am changing our engineering standards to require future installations to employ drawout power breakers for major loads, but we use many smaller power panels and switchracks and those feeder breakers will need to be tested to validate their condition for arc-flash.
