Is this a fault or a feature? Isolation transformer internals...

[Paringa]

Hello all,

 

Just purchased a new Isolation Transformer and taken off the cover and found this. See pic.

 

I thought initially it was a capacitor that had spewed its insides out but now i think it may be some silicone? Certainly feels like that.

 

Can one of you experts cast your eyes across it and see what you think.

 

I have contacted the seller and am not able to test it by connecting to shore power... But i don't want to do that until the seller gives me the okay.

 

Am i worrying unduly?

Looks like it could be silicone does it feel like it?

It's an adhesive of some sort. Stops vibration causing fatigue damage to the capacitor leads. Failed electrolytic caps don't look like that. Victron may have had some failures of the caps in that position, so added the glue to stop them moving. All is fine!

Some pics of failed electrolytic capacitors and some with glue on them here.

Just so it doesn't surprise you once connected, the Victron isolation transformer gives a 10% higher output than input. The halogen lamp in our oven didn't like it.

Thanks all. Feel much better.

Most transformers do this, if feeding a Victon Combi you have to alter the acceptable input voltage or the combi  shuts down.

Just out of curiosity, why did you take the cover off??

How else could you wire it in?

Ahh - that’ll be me not looking at the photo properly!!! 

 

I’d kind of assumed that wiring connectors would be presented to the outside of the cabinet so that the installer didn’t have to open the box.
