Ansi neta mts frequency of maintenance tests
Hard to reach bolts in areas of poor access done by 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, ms-2007 seem as diligent as I thought we were in the past.
Is the testing valid? Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Having been in this business, that runs up a bill pretty fast. We still had to make sure the trip elements works, but a functional test of the trip was way easier to perform than pulling a breaker out of the unit to test. Improper or inadequate maintenance can result in increased opening time of the overcurrent protective device, thus increasing the incident energy.
Yes, anssi-neta the most part. Others have the electro-thermo-mechanical devices. However, here is the issue with NETA tests, they require the breaker to be opened and removed from service to test trip times, which does not represent a mtx-2007 world condition. It is a very good tool, and I recommended it to several clients after I went back into power system field services. Ah, the prospects of retirement This significantly increases the incident energy exposure in an Arc Flash scenario.
There is however a larger over arching issue at play: Close this window and log in. Outside those areas, you’re going to be paying for expenses and mileage in addition to personnel cost and test equipment cost.

Have them put that in their pipe and smoke it It did indeed point out some issues with transmission and distribution breakers. The Eng-Tips mta-2007 will check this out and take appropriate action.

I have a customer in my area struggling with many of the same ansi-meta 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. I’m working on this.

I’m interested in seeing other thoughts. Most if not all of the electrical equipment and Molded Case CB’s have been in place for 25 years without even being exercised. Arc flash is concerned with the interruption time which includes the arcing time within the interrupter. I have been adamant in my pursuit to have the company bring in a NETA-certifed contractor to perform verification tests on all of the OCPD’s, but they seem to be taking the stance of “well, we,ve never needed this before The arc-flash study is supposed to consider the “condition of maintenance” of the equipment.
There are many ways to catpure this data, this device is new and perhaps the most simple way to do it. I have to bring in a contractor with a test set that is towed in on a trailer.
The edition fo the NFPA 70E is going to make some major changes regarding this subject, futher details of maintenence requirements and the vadility of the arc flash study.

He may have to travel with said trailer for several hundred miles to my site in Armpit, Mississippi, for which I pay, and 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.
Unbolting twelve bolts on the bus side connection and disconnecting twelve thumb-sized cables on the load side so that the break can be tested is a problem.
Can it be done? Defense manufacturing is all about project manufacturing and project accounting. I’m looking at similar issues. Whoever does the arc-flash study should recommend maintenance testing of the protective devices as part of their report. Perfect tool for validation of an arc flash study though.
I think you are basically correct. If you’re around a major industrial area, testing companies, both NETA and otherwise, may be available. Are you an Engineering professional? Download Now Defense manufacturing is all about project manufacturing and project accounting. When you add to that the electrical risk, where you know you’re going to have to work on live equipment and you’re going to see sizable electrical outages because by nature the breakers you’re interested in testing will be critical feeders, I see NFPA ansi-ntea as offering more hazards than it corrects.
