Managing transient faults: How to cut costly short interruptions

Momentary outages are a growing pain point for utilities. Could reclosers prevent the associated losses?

Recorded: 25 Apr 2018

Webinar Overview

Utilities have been struggling with short interruptions since electricity grids began operating.

The majority of faults on overhead lines are transient in nature caused by weather or temporary technical issues.

They have a growing impact in an increasingly digitised economy where the majority of new renewable generation is connected to distribution feeders, and require a significant response from utilities.

In the past, quantifying the extent and impact of transient faults, against investment to reduce them has been difficult, and there have been limited options to manage them.

Legacy fuse technology offers limited solutions. For momentary outages on spur lines, the utility will set its system one of two ways: fuse-saving or fuse-breaking.

These options result in widespread short interruptions or sustained outages for large numbers of customers on the spurs.

Auto-sectionalisers are similar to a fuse-saving scheme in that they avoid sustained interruptions on the spurs, but result in all the customers on the main line being affected by short interruptions as they rely on the upstream breaker.

In response to these issues, global provider and electric service provider S&C Electric Company has devised a recloser solution for spur lines.

The product, TripSaver II, avoids affecting any more customers than necessary, reducing both sustained interruptions on spur lines and more widespread short interruptions.

It can reduce costly issues of distributed generation being tripped off and being unable to export.

In this webinar, Christopher McCarthy, Managing Director of EMEA at S&C Electric Company, will outline the issues facing the market surrounding grid reliability and power quality.

He will also present the TripSaver II and how it eliminates the issues associated with fuse-saving, fuse-blowing technologies and auto-sectionalisers.

As part of UK regulator Ofgem’s price control period, RIIO-2, there is an opportunity for new regulatory incentives to be introduced in this area, which cover the impact on distributed generation as well as demand customers.
