relay test set 3-ph module

relay test set 3-ph module

relay test set 3-ph module

(OP)
We have an old relay test set, RTS-150 made by EIL (now Ametek), it contains an add-on module which gives the test set 3-phase capability.  But we don't have any instructions on how to use the module.  Can anyone help us with wiring this module into the test of a 2.5 element transducer?  Thanks

RE: relay test set 3-ph module

Without knowing much about your EIL test set, I would guess that the 3 Ph module "synthesizes" a 3 phase delta voltage, similar to the old Multi-Amp Sr-76.

It's unlikely you would get 3 ph current.

Generally speaking, you can test a transducer like a meter with a single ph test set.

What concerns me is that with this vintage equipment, you are likely to loose any kind of accuracy.  Do you have a reference transducer to compare with?  What are you using as the DC meter?

You may find it easier to either rent a modern 3 Ph test set or hire a test company that has one.

I was on a IPP commissiong job years ago where another company "tested" the transducers using  a Fluke 87 and an old SR-76 (similar to EIL).  All of the emmissions tests were performed using transducer data.  $100k later, it was determined that the source/test equipment was not of sufficent accuracy for the device under test.
