Transmission Line Resiliency

Resiliency is a term used more and more by transmission line stakeholders including designers, operators, and owners. Resilience is simply defined as toughness or the capacity to recover quickly from difficulties. It can be used to describe a system, an object or even a person. Dr. Ginsburg, child...

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...

Cable Testing Comes of Age - One Cycle at a Time

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....

Application of Symmetric Conditions in the Simulation of High Voltage Power Transmission Models

The height of the power transmitting towers is usually in the range of 10m to 40m and the separation between two consecutive towers is about 200m to 400m. In addition, the area of the ground that needs to be considered in the simulation is large. Therefore, Finite Element Method (FEM) is not suitable for simulation of this application. Whereas Boundary Element Method (BEM) is best suited for these open region problems. This paper refers to...
