Protective relay test standards
(OP)
What standards that manufacturers should comply when doing their protective relay type tests or product tests before release the products?
Thanks

Protective relay test standards

RE: Protective relay test standards
As an example for North American market, I would check in the manual for a SEL relay (specifications). I recall seeing a listing there of the various tests (standards). From what I have read of them, they have to due with impulse (dielectric) strength, EMF immunity, etc.
There are other types of tests, such as IEC 61850, that I believe KEMA (independent test lab) performs.
I have read that there is a new IEC standard, directly affecting distance relays that spells out the steps and how things should be tested. I am not aware of a similar IEEE standard.
The link below describes tests in general from Areva/Alstom.

In Mexico, there's an independent lab which is part of the electrical utility.
This lab perform many tests (static and dynamic, as well as having installed a pair of each relay as a backup protection with only alarm-not trip- during a period of time)to each relay that may be used on the transmission, distribution network as well as power stations.
Only after passing satisfactory all the tests, the relay and reclosers are included on a "list"(kind of UL list).
In any bidding, project, upgrading the electrical utility onl accepts "enlisted relays", in that way, the number of "deffects" is reduced and network reliability is increased.

Would you mind let me know which Lab, phone and email?
Thanks
