At the work place. When proving an 11KV Transformer is Dead. We have HV test sticks. With a function test. Part of the procedure is to function test. The HV stick before & after. Testing for Dead. I personally believe an HV "Proving Unit" should be used. To Prove Dead.
Is a HV stick self function test ? Enough on its own to verify. The test instrument is working ?. Or is there a HSE law or other ? That states. A voltage Proving unit. Should be used
