Rogowski coil meter interface with Teridian 71M6513

Posted: 10 May 2011     Print Version  Bookmark and Share

Keywords:3-phase  electronic power meter  current transformers 

The Teridian 71M6513, 3-phase electronic power meter device has been evaluated primarily with current transformers as the sensor for determining the accuracy and linearity of the device in electronic meter applications. An alternative current sensor that can be used is the Rogowski Coil. To use a Rogowski Coil, the input signal conditioning circuit to each of the current inputs (IA, IB and IC) of the 71M6513 needs to be modified slightly. A small modification to the meter firmware is also required.
