APPLICATION GUIDE
This application guide is intended to illustrate the extensive range of application and schemes to which our products and systems can be
applied. For ease of use typical schemes have been provided to cover the standard voltage ranges.
Our company specialises in customised applications and we have a dedicated team of senior applications engineers who can provide
solutions for any voltage in the power system network.
The voltage levels indicated in this guide are as follows:-
i) LV typically less than 1kV
ii) MV typically 1kV to 132kV – Distribution
iii) HV typically 132kV and above – Transmission
