Field Testing of MV and HV cables has come a long way in recent decades. Gone are the days of old, when the traditional DC (Direct Voltage/Current) hipot was the recommended method for testing these modern cables that form the critical backbone of the distribution electrical power network. Extensive research, often rooted in the hard lessons learned through negative experiences in the field, has brought about changes to and improvements in the approaches...
Background:For over 100 years Transmission Engineers have relied on aluminum conductors strengthened by steel core wires, commonly referred to as ACSR conductors. These conductors offered reasonable performance and durability and were capable of operating at temperatures up to 93° C. Above this...
This project won EEI Transmission Project of the Year – 2016 Description: 240 circuit miles, 345 kV line, double bundleProject: Replace 1,440 miles of ACSR conductor with ACCC Objectives Improve reliability (reduced sag and corrosion) Increased capacity to serve growth (2X...
Essentially, cable cleats are devices designed to secure cables and to ensure the retention and support of them, reducing the load that the cable may be exposed to under its own weight. They are also designed to contain the cables under fault conditions, protecting the cables and the cable...
In a significant move that underscores the growing demand for reliable and sustainable energy to power the expanding digital infrastructure, the Federal Energy Regulatory Commission (FERC) has approved an interconnection agreement between Talen Energy, Amazon Web Services (AWS), and Exelon. This...
A coalition of large energy consumers and ratepayer advocates has filed a complaint with the Federal Energy Regulatory Commission (FERC), urging the agency to prohibit transmission owners from independently planning "local" transmission projects exceeding 100 kilovolts (kV). The coalition argues...

To support decarbonization mandates in the U.S., many utilities and transco's have proposed new transmission lines to link load centers with new renewable generation assets and move power from one region to another over vast distances. While the U.S. government continues to struggle to find ways to...
Brief Background: In the early 1900’s Aluminum Conductor Steel Reinforced (ACSR) conductor was developed to replace copper wires, due to the war effort when copper was needed for munitions. In the 1970’s growing demand for electricity inspired the development of higher capacity...
