This project develops Sensitive Earth Fault Protection for LV Feeders that would be installed as a temporary retrofit before the commencement of any live working and removed after the work has completed. The additional protection would act to help prevent severe injury or death from inadvertent human contact with a live phase conductor during work on an LV feeder.

Objectives

The project naturally divides into three workstreams:

·         A workstream to test alternative methods to detect contact between a human and a live phase conductor, select the preferred option then produce and test a prototype detection device

·         A workstream to define and test a retrofit device which can act on receipt of a signal to cause mains supply to be quickly removed from an LV feeder.

·         A workstream to integrate the prototype supply interruption and detection devices and then test them in the field.
