I was sitting with a customer in his office the other day and asked him why he always rented the Raytech WR50-12 unit from us when we had smaller, lighter, cheaper units available that were rated to do his jobs like the Raytech WR14 available.
He took the time to explain to me that when he is testing windings he likes to have the higher current available in order to test the load tap changers. So, while technically he could get the job done with 15A, 50A lets him do a more comprehensive job.
So Bob, thanks for the education!
Everyone else, if you want to check the load tap changers next time you are testing windings and you only have a 10A or 15A set give me a call, we have what you need!
