The measurement engineer can view the values from tan δ and partial-discharge testing directly in the cable test van. Clear representation helps to detect severe defects or locate partial discharges ...

Testing medium-voltage (MV) cables with the high-potential (“hi-pot”) test is typically part of an MV cable testing program. In Parts 4 and 5, we looked at the DC and AC versions of this test. The ...

How good are my cables? Are they like new or slightly, moderately, or highly degraded? Tan Deltatesting is a non-destructive diagnostic test performed to measure the condition, or level of ...

The IEEE recently approved IEEE 400.2, “Guide for Field Testing of Shielded power Cable Systems Using Very Low Frequency (VLF), a new standard that addresses concerns when field-testing shielded, ...
