How Vibration Damper Works in Transmission Line?

How Does a Small Size Damper Reduce Vibration in Transmission Lines?

Vibration dampers are usually used in high voltage and extra-high voltage electrical energy overhead transmission lines to handle aeolian and galloping or dancing vibrations in the transmission lines' conductors. The dampers are designed in such a way that they attenuate the line vibrations by reaching the same frequency as the cable that has wind-induced vibrations.

The overhead Transmission Line mainly experiences two types of vibrations in a vertical plane which can be categorized into two groups.

  • Aeolian Vibration;
  • Galloping or Dancing vibration.

Calculating the Resistance of a Wire


In many cases, we will know the length of a wire l and the AWG (American Wire Gauge) or 
SWG (British Standard Wire Gauge) or IEC standard size of the wire, but not the resistance. It's easy to calculate the resistance though.

Wikipedia has a list of AWG specifications available here, which includes the resistance per meter in Ohms per kilometer or milli Ohms per meter. They also have it per kilofeet or feet.


Underground High Voltage Power Cable Jointing, Bonding, and Earthing

The cable joints are basically used to connect low voltage, medium voltage, high voltage, and extra high voltage cables. All joints must provide electrical insulation as well as mechanical strength and protection. 

Cable joint sizes, shapes, and configurations may vary according to the voltage range, structure, insulation, and the number of cores of the cable to be jointed.

Partial Discharge in High and Extra High Voltage Lines

Partial Discharge (PD) is very important for Underground Power Cables. If you work with Power Cable, you must know why and where Partial Discharge is present. It will help to take action at the right place at the right time.

Campervan Travel - Visit Castles to Explore the History and Have Fun This Summer!

In a few months, the sun will shine in its full glory in the UK, giving a perfect excuse to everyone to go on a summer break. Whether solo or with family, you can make the most of your weekends by hopping to the emblems of the heritage of this sovereign country, i.e., castles. If some sit atop the cliff edge as ruins, others carry the battle scars in the surroundings of the moat and drawbridge. A few possess fairy-tale-like charm with towering minarets in thrilling woodland settings. While each holds a magical pull, you can hire a camper to make your journey to each of them more memorable.

What is Machine Learning?

What is machine learning

The Machine Learning concept, a branch within Artificial Intelligence that provides computers with automatic learning without the need to be continuously programmed, has taken on greater prominence in the last decade. In just a few years, algorithms classified as Machine Learning have evolved to manage large volumes of data (Big Data), obtain better results, and solve problems more efficiently.
