He should test all of them. TTR, DAR/PI, winding resistance, IR.

Customer is the king-it is not a cliche, but reality in actual life.He will decide- but many times when a large number of transformers are offered,inspector selects one of them and ask for testing.Power transformers are witness tested usually only the first unit. But nowadays 100 % testing is the order of the day.

I am going to assume that these are tried and proven designs. If I were the client, I'd probably like to see the testing one one representative of each, then review the reports on ALL the transformers, but seriously, at these capacity levels, unless I'd asked you to do something out fo the ordinary, I'd probably NOT sit around after the initial factory visit.

However, being the client, I would think I had the right to do so, and you, as the vendor, should be welcoming and accommodating as long as I was safe and out of the way.

It depends on what was specified in your proposal and/or your customer's order. If testing was part of the specification that you bid to, then the question is how much, where and when. If he didn't ask for testing and your company didn't allow for testing in the price of the product, then any testing that the customer wants should be an extra charge.

Go back and read the spec and your bid proposal.

But... as stated, no matter which of the above it is-your cost, his cost-the customer is king and he still has the money in his bank and you want it in yours.

I read this as not that the tests are being questioned, but as to the customer being present during those tests...

We always bought our transformers with the writing in the purchase agreement that we reserved the right to observe such tests -- which we never did, and what was explicitly assumed was that we, the customer, bore the costs of witnessing such tests...

So, review the contract -- if requested tests are not in the purchase agreement, then negotiate with the customer to include the tests as an option with the customer bearing the additional costs... if the customer just wants to witness the tests, by all means, make them available for the customer to witness, but at his cost.... any other option does not reflect well on your integrity.. in my opinion
