Amped I is in the process of replacing antiquated current and potential meters on critical substation systems with new digital technology multifunctional meters at multiple 12kV and 4kV sites in Illinois. Only a local digital display exists for many of these meters and it is essential to have remote, up-to-date and real-time access to full analytics pertaining to essential equipment such as transformers, feeders and voltage regulators. The need for remote data output was essential to this design, so new meters are either to be connected to existing remote terminal units or to newly installed remote terminal units. After further evaluation, Amped I is utilizing existing power, current transformer and potential transformer cables to save the client resources.
