Smart Grid Sensors bring real-time situational awareness to utility crews, engineers and planners. These new technologies must complement existing technology installed at substations and on the circuits.

Improving Fault Current Accuracy Application Guide - Aclara Grid monitoring

The information and results provided by every device on the line must be consistent and minimize each vendor’s proprietary methods. This application guide covers:

  1. New digital filters on sensors to reproduce results provided by relays using CT circuits.
  2. Current methods of calculating PEAK and RMS values.
  3. Results of lab testing of new digital filters.


The new features discussed demonstrate results typically within 5 percent of the most commonly used relays’ measurements.
