Utilities Medium Voltage fault detection methods
Utilities Medium Voltage fault detection methods
(OP)
I'm trying to determine how other utilities identify the faulty medium voltage cables after a switchgear trip in a main substation. Assuming that a network is entirely underground, do you measure each segment of the network and a progressive feed oh healthy sections or you do live connection of the switch gear until you find the faulty one?
Can you help?

RE: Utilities Medium Voltage fault detection methods
In some cases where EFPI are not yet installed; then faulty section is identified by energizing the cable section in sequential way starting from main substation. This could result in re-tripping of the restored customers or sometimes healthy customers.
