Fluke flexible probes

[Davebones]

Just got a Fluke 376 amp probe . This has a flexible current probe . Would like to install this in a panel and occasionally come back and plug in the meter to take a current reading . I know about grounding the secondary of CT's just wondering is there a hazard leaving the leads of this flexible probe hanging out without being plugged into a meter ?

I don't think anyone's going to tell you there's no hazard associated with that or anything else electrical. Can you put a (lockable) box aside the panel and have it terminate in there such that someone has to open that box to access it? It would be quicker than removing a dead front.

Was going to leave the cover on and have the end of the probe hanging down below just acessible to plug in the meter .

Since the current probe is acting as a current transformer with a saturable core, you should not have a dangerous voltage across the open circuited secondary. But you can confirm this by measuring the voltage.
It would still be wise to protect the end of the probe in some way.

I looked at the manual. The sensor output is not a current, it is a voltage. It is not a CT. There is no concern about grounding the secondary.

GD - I'm not familiar with "saturable core CT". How is it you know this is the probe construction? It is not a hall effect (won't measure DC Amps). I would guess it is a Rogowski coil.

That should work fine. As suggested measure the voltage. - I have two guesses:

1. Less than 2.5V.

2. The book shows three connectors to the input. It is not a rogowski and the third connector is for input power. if so, if not plugged into the meter, output is 0V.​

Just non-random guesses - worth about what you paid for them :roll:

Where do we go to get our money back if we are not happy with results?

Do thank you for the information guys .

Might be owed to you for a long, long, looooonnnnggg time - but I'd never cheat you out of it. :angel:
