1)what is hypo test. 2) which cable need to hypo test.3)
when hypo test can be done before or after glanding.4) what
is the purpose of hypo test.
Answer Posted / shams
hypo test is mostly used when any new cable is used or any cable which is repaired like tertiary cable in transformer.it is used to test the leakage current.20kv to 100kv dc is applied through hypo device to the testing material then the hypo device shows us the leakage current of that material
