Practical Earthing Handbook for Power Engineers
It is pertinent to mention that Earthing plays an important role in proper operation of generation, transmission and distribution systems. The function of earthing in an electric power system is to maintain the potential of current carrying as well as… Read more
Electrical safety hazards awareness (with realistic work scenarios)
Electrical workers are frequently in close proximity to energized parts where power arcs can occur. It is not necessary to touch an energized conductor to receive an electrical shock. Anyone who has rubbed their feet across a carpeted room and… Read more
Relay Coordination Study: Calculation of the protective relays setting value to obtain selectivity
The scope of study involves calculating the settings for protective relays to achieve selectivity during faults ocurring in the electrical network for the 13.8 kV and 4.16 kV projects. The protective philosophy is fundamentally grounded on the understanding that faults or… Read more

Why and where Rogowski Coil current sensors are favorable when compared to CTs
Rogowski Coils can easily replace conventional current transformers in protection, metering, and control applications. They can be applied at all voltage levels (low, medium, and high voltage). However, unlike CTs that produce secondary current proportional to the primary current, Rogowski… Read more
