This technical article covers protective grounding requirements for steel tower and wood pole supported transmission and distribution lines, and insulated power cables. Protective grounds must be installed so all phases… Read more
The transmission media that provide the communication links involved in relay protection signalling are private pilots, rented pilots or channels, power line carrier, radio and the newest and the most… Read more
It’s quite simple, using shunt capacitor banks to supply the leading currents required by the load relieves the generator from supplying that part of the inductive current. Both distribution and… Read more
Animals are one the largest causes of customer interruptions for nearly every electric utility worldwide, right after human and other factors. Problems and mitigation techniques are as varied as the… Read more
Like any other major component of the high voltage electrical network, a switchgear also needs maintenance schedules for trouble-free operation during its life cycle. No one should work on the… Read more
Nowadays, system design engineers have a choice of many types of systems that may be used for a particular application. This discussion covers medium voltage distribution systems and their practical… Read more
This technical relies on the previously published article (6 alarms coming from a substation transformer you MUST take very seriously), but is much more dedicated to the implementation of relay… Read more
