System Overview 

5.1

 

System Overview  

The Nortech EasyGrid signal conditioner is design to monitor fiber optic temperature sensors installed 

inside high voltage power transformers.  Immunity to electrical interference and high dielectric constant 

procured by fiber optic sensors allow direct contact with high voltage components.  It is the only 

technology that monitors the true winding temperature in real-time.   

 

To be functional in its target environment, the Nortech EasyGrid is part of a system that includes the 

fiber optic sensors and all the components in between.  The figure below gives you a general idea of a 

typical installation. 

 

 

 

In this section we will describe the different component required to have a complete winding 

temperature measurement system.  Note that all components specified in this document are available at 

FISO; contact your sales representative if you need more details.
