Insulators' ageing in North America - How about testing them?

Sediver has established in the USA an assembly factory for glass insulators in 2017 but also, and perhaps more interesting for some engineers, a laboratory capable of performing all the tests required by the world’s standards. Large test campaigns have already been conducted in this...

Lightning Strikes

In Canada, lightning flashes occur about 2.34 million times a year; with the highest levels of concentration during the summer months. While most lightning on earth is ground-to-cloud, recent research has identified that the majority of lightning events to tall structures, such as wind...

Utility Fleet Tracking Myth Busters

Since global positioning system (GPS) tracking was first introduced to the fleet industry, users have debated whether this technology is beneficial for their fleets. Some of the most common objections include the fear of employee pushback, budget concerns, and usage apprehensions regarding Big Data.

Additionally, GPS tracking presents a learning curve, which means that utilities have to train their employees to use the technology. Moreover, daily operations swamp utility employees.

The aforementioned challenges present...
