About Transformer Analysers & Ratiometers

A radiometer is a device used to measure the intensity of radiant energy. A majority of radiometers use only single photocell sensors. To measure radiation emitted from a specific spectrum or to incorporate the radiometer within a certain spectral response, an optical filter is normally used.

Transformer analysis is completed for maintaining the specifications and performance of an electrical power transformer. The transformer is the main part of an electrical generation/distribution system so if it is not working properly then it will affect the whole system.
