Solving Underground Cable Problems with Partial Discharge Testing

How to prevent failure with partial discharge testing BY HENNING OETJEN, Megger Partial discharge (PD) measurements are increasingly used as a reliable and non-destructive diagnostic method to detect weak spots in the insulation of underground cables. Routinely, partial discharge measurements are...

The Evolution / Revolution of Overhead Conductors… and why it matters

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 Aluminum Conductor...

Why technologies are important to grid modernization

BY MANI VADARI, Modern Grid Solutions

Electricity is one of the cornerstones of our economy. A modern electric grid is critical for our economic and national security. The National Academy of Engineering has called the North American power grid the “supreme engineering achievement of the 20th century”. Today’s power grid was designed to deal with a power delivery paradigm that we are slowly moving away from. The...
