Based on their understanding of the importance of a healthy and reliable cable network, distribution system operators (DSOs) strive to meet two major objectives: minimize maintenance costs while ...

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 ...

As established in Part 1, you must test medium-voltage (MV) cables to know their condition because of the many factors that can cause premature cable failure. Those failure factors include: • ...
