Climate Change Threatens Canadian Wildlife and Winter Habitats

As climate change accelerates, its effects on wildlife across the globe are becoming increasingly evident. In Canada, one of the countries most affected by warming temperatures, the changing climate is threatening biodiversity, disrupting ecosystems, and impacting species that rely on harsh winters for survival. A recent report highlights how these changes are not only reshaping Canada’s landscapes but also undermining the delicate balance of life that many animals depend on to thrive.

Utilizing Fault Resistance to Test Distance Relays

Taking power grid protection to an all-new level

BY JASON BUNEO & RENE AGUILAR, Megger

The testing of distance relays has evolved from testing simple electromechanical relays to the newest modern microprossesor relays. Most modern relays employ advanced algorithms that not only compare the direction of voltages and currents in the system but also rather look at other system components. For example, many modern relays utilize various methods in order to determine the direction of the fault such as negative sequence impedance, zero sequence impedance, cross polarization, and others. This is only one of the many parameters that make up the distance protection.

Due to this increase in complexity in distance relays, the test methods have also evolved from the simple traditional methods of injecting simple arbitrary test values to requiring more realistic test values. It is important to understand how these newer devices function in order to be...

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...
