Following on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea. Traction substations...
For unbalance conditions the calculation of fault currents is more complex. One method of dealing with this is symmetrical components. Using symmetrical...
Fire resistant and fire retardant cable sheaths are design to resist combustion and limit the propagation of flames. Low smokes cables have a sheath designed...
Over the past year or so I've been involved in on going discussions related to referring fault levels from the secondary of a transformer to the primary...
