Major grid disturbances may begin due to many different causes. Protection functions are used to trip the circuit breakers to disconnect energy supply and load according to the characteristics of the disturbance. Protection devices have played a major role in initiating, propagating, and preventing major power system disturbances in the past. Protection engineers have developed a very high degree of competence for designing and configuring relays to be reliable, sensitive, and secure response to short circuit events. Read More

Due to the accelerated shift towards a carbon-free electrical energy system, the power system is changing in terms of both planning and operation with an increasing integration of converter-interfaced renewable generation at all voltage levels.Read More

The worldwide energy landscape is undergoing a transition, the pace of which varies in different parts of the world. From system operation perspective, the main factors identified contributing to this ongoing energy transition are threefold.Read More

Even the recent crisis has not held up our new Digital ELECTRA by more than a week or two! We are currently testing the system and we are pleased to advise the new digital offering will be available for the June edition of ELECTRA.Read More
