Four steps to faster catenary flashover recovery

1

LOCATE
Identify exact location of flashover

2

DISPATCH
Repair team to the problem location

3

REPAIR
Correct issue and inspect for damage

4

RECOVER
Re-energise section and return into service

We listen to locate catenary faults

The Sensonic flashover location application delivers railway operations and overhead maintenance teams’ precise location of overhead flashover faults.

  • Find faults quickly
  • Repair and inspect only the problem equipment
  • Get lines re-energised faster
  • Reduce disruption

 

Directing teams to the exact problem location avoids time being wasted inspecting whole electrical sections and reduces the likelihood of reporting “no-fault-found”. It also decreases the time and distance of teams on-track reducing staff risk.

Left - A tree leaning over a railway and a branch touches the overhead electrification wires. Right is a graph showing vibration data from the original event and 3 subsequent attempts to energise the overhead catenary. Each attempt to re-energise creates a flashover which is seen in the vibration data.

Remotely knowing the exact location of a flashover can greatly improve the time to find and fix overhead catenary faults.
