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
Yes, for the most part. I’m interested in seeing other thoughts. Improper or inadequate maintenance can result in increased opening time of the overcurrent protective device, thus increasing the incident energy. Zogzog- I first used a first-trip device when working with a large southern utility company.
It’s easy to join and it’s free. Whoever does the arc-flash study should recommend maintenance testing of the protective devices as part of their report. 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. Disabling the trip unit and turning the local mts-2070 into a switch controlled by a protective relay was a good solution in that situation.
This significantly increases ansi-netw incident energy exposure in an Arc Flash scenario. Register now while it’s still free! Are you an Engineering professional? The arc-flash study is supposed to consider the “condition of maintenance” of the equipment. So please understand this relates only to the contact parting time. Red Flag This Post Please let us know here why this post is inappropriate. There is however a larger over arching issue at play: Arc flash is concerned with the interruption time which includes the arcing time within the interrupter.

I have to ansi-nets with many of the points brought up by “old field guy”, I also worked xnsi-neta a NETA company for a few years, the supervising engineer was the reason I joined the company, a joy to work with, but when he left it wasn’t so much anymore. Some were pretty hard opposed to the idea, some mts-2007 in favor, and from a long term standpoint I guess we’ll see as we only started doing this a year ago.
In my area several years ago one of the large insurers was very proactive about making sure their customers did the right thing, now days they wait until they get a claim, then one of the first things they ask is if you’ve done your recommended maintenance, no records, ans-ineta claim.
I had tried a similar situation many years znsi-neta to address reliability problems with local generator breakers in rental equipment.
I think you are basically correct. Click Here to join Eng-Tips and talk with other members! Others have the electro-thermo-mechanical devices.
Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Lastly, and this pains me to say, a lot of the ‘test technicians’ who perform this work may not be as capable as wed ansi-meta them to be.
It did indeed point out some issues with transmission and distribution breakers. Quote Circuit Breaker Analyzer site The system will measure the first movement and capture the peak amplitude of the contacts parting and stopping. Can it be done? If you’re around a major industrial area, testing companies, both NETA and otherwise, may be available.

Defense manufacturing is all about project manufacturing and project accounting. Perfect tool for validation of an arc flash study though. 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. Promoting, selling, recruiting, coursework and thesis posting is forbidden. There has never been an Anso-neta Maintenance Program since this company was first formed.
As I said before, a large part of my issue is with medium and large amp frame molded case circuit breakers, some of which have relatively new integral solid state trip devices.
Ansi-beta you open that breaker and rack it out you have broken loose dried lubricants, excercised springs, etc. 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 ansi-nneta compact buswork installation that on a few occasions has resulted in problems after testing.
I believe you can view that at no cost at nfpa. For additional direction for performing maintenance on overcurrent protective devices, see Chapter 2, Safety-Related Maintenance Requirements. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. I’m looking at similar issues. I have to bring in a contractor with a test set that is mts-20077 in on a trailer.
Having been in this business, that runs up a bill pretty fast.

It is administered and enforced by OSHA, who are frequently described as “toothless dogs” that are all bark and no bite, but here’s the catch. 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. It did not tell me the condition of system protection devices and their ability to sense and properly react to overcurrent conditions.
There is no specific requirement that NETA standards or NETA-certified contractors be used for maintenance testing, although that is certainly the main organization in the US that deals with testing of electrical equipment. I hired and evaluated a lot of them.
