For fence leakage conductance we have used 1x10^-11mohm/m successfully. For a wet cedar fence post which we consider leaky we have used 1x10^-7mohm/m. I do not remember where these numbers came from. The closest fence I have worked on that is similar to your picture was a barb-wire fence, so...
Thanks for the responses, rain held up re-testing.
First tests were done with ground bar disconnected from neutral side on the phase under test (H03 terminal) and H1, H2, H3 terminals had no trainers connected. Error existed.
Same configuration but with H01, H02, H03 terminals all shorted...
Saturation tests were performed and I was told they were good. I am waiting to see the test results to verify. Our test set will show voltage and current points as it is performing the saturation test, but that is all. They have not yet viewed the excitation current to verify there isn't a...
Hello,
We are commissioning our first 345kV shunt reactor and are finding 15% error in measured CT ratio tests on all bushing CTs.
Manufacturer states that when tested outside of the bushing, all CTs were good, but their testing when CTs were mounted showed same results we are getting. I am...
