1.1.

 

Product purpose

 

 

LYNX 4400 fault detectors are designed to be installed on the underground sections of MV grids earthed by 
means of a limiting resistor or impedance. The detector enables the following aims to be achieved:

 

•

 

Improving detection performance

 

•

 

Counting faults and changing the operation of auxiliary contacts

 

•

 

Standardising cores, PPACS, indicator lights and their connections

 

•

 

Standardising and extending the usable lives of batteries and supercapacitors

 

•

 

Using plug and coded type connectors for connecting current probes
