Switchgear solutions: Reclosing on 10-38kV underground circuits

Automating fault detection and resolution on underground feeder lines can save customer interruptions and minutes lost. This technical webinar explains how.

Recorded: 11 Sep 2017

Webinar Overview

What is the impact of closing and reclosing in resolving underground faults? This webinar clearly explains the types of faults that can occur on underground feeder sections and the negative effect that reclosing practices can have on distribution assets. Drawing on data from UK distribution network operators - where an estimated 8,000 faults are reported on underground cables per year - this webinar also identifies how faults on mixed overhead and underground feeders are the most difficult to manage for reliability and protection.

Your speaker Christopher McCarthy, Managing Director for EMEA at S&C Electric Company, explains a solution for fault resolution that reduces the need for complicated excavations as well as manual intervention - pulse closing. Among other benefits, pulse closing is estimated to use 95% less energy than reclosing preventing damage to your system during fault testing.
