Which Test Kit.

[ChrisElectrical88]

Afternoon Chaps. We’re doing more and more EV Chargers. I have the Megger 1711, however when I do the charger I borrow my good mates 1741+.
We have the Rolec box for testing aswell.
I’m now looking at the Fluke 1664FC tester, has anyone got it, ideally I want to move away from Megger, I keep having issues.
cheers

I have the FLUKE 1664FC and find it's possibly the best MFT I have used, particularly the "Auto Test" function and populating the Fluke Software, although the software does look a bit dated, it is automatic from the USB connection or even Bluetooth.

 

[ChrisElectrical88]

Will it test do a 6mA DC test for the EV Chargers?
What does the Auto Test function do exactly? Cheers

Easiest way to answer all your questions is here: https://www.fluke-direct.com/pdfs/cache/www.fluke-direct.com/1664fc-us/manual/1664fc-us-manual.pdf

The Auto Test does five tests one after the other all from a socket with a plug in connector, but do read the manual it's a mine of information.

What about Metrel

Never used it, just had a look and I don’t think I like the touch screen. Rather keep it simple with dials

The problem with asking a question like this, is that most people stay loyal to whatever they buy first, so not many have used multiple products from different manufacturers, I am guilty of this only having use three different types, but still keep going back to Fluke.

When I have been onsite with other sparks just to keep the testing consistent most of the time you generally use one meter so I have used some different meters but you always feel more comfortable when you get back to your own meter
For me if it is a multimeter it's generally Fluke, MFT it's Metrel not the go to for many electricians but I like them
So as you say opinions can be biased to what you use

Is it the case that to properly test the current EV chargers the tester needs to be capable of testing rcds with 6ma dc current?

I wonder if everyone fitting the EV chargers is actually doing this? Or if they actually have to?

Which MFT are capable of this besides the Megger 1741 plus.

 

[Mike Johnson]

On the Megger 1741 Is that a specific 6ma dc current test or during a ramp?

 

[Mike Johnson]

Ah ha I see its a specific test that the Megger 1741+ can do.

 

[Mike Johnson]

My post has been edited? It asked if anyone was willing to see the difference between a 6ma test and a half wave test on an RCD.

Yes it is just to add to be able to do the 6mA DC test on the EV Charger. Looking at the 1741+ now.
Spoke to a rep from fluke who said do a Type A RCD on 10mA and that’s alright to do but I’m a bit wary.

Interesting, I had forgot that the Fluke had the ability to test at 10ma, I assume that the test on a EV instal requires a test at 1/2, 1 & 5 so 3, 6 & 30 , the Fluke could do this at 5, 10 & 50, it would be very interesting to compare the results obtained between a dedicated tester and the Fluke or any other MFT that offers lower settings.

Gone for the fluke.
