Circuit configurations (single line diagrams) for HV and MV switchgear installations
The starting point for planning a switchgear installation is its single line diagram. This indicates the extent of the installation, such as the number of busbars and branches, and also… Read more
Primary Injection Testing Of Protection System For Wiring Errors Between VTs / CTs and Relays
This type of test involves the entire circuit – current transformer primary and secondary windings, relay coils, trip and alarm circuits, and all intervening wiring are checked. There is no… Read more
Protection Of Industrial Power Supply Systems (Fuses, MCCBs and Overcurrent Relays Settings)
As industrial operations processes and plants have become more complex and extensive, the requirement for improved reliability of electrical power supplies has also increased. The potential costs of outage time… Read more
Protections For Medium Voltage Synchronous Machines (Generators) – IEEE C37-2 Codes
The protection system for MV generators (synchronous machines) must be carefully selected and studied for the application it is destined for and it is not normally possible to define a… Read more
HV Substation Equipment For Engineers In a Nutshell
Substations are locations where transmission lines are tied together. They fulfill a number of functions. One of them is that they allow power from different generating stations to be fed… Read more

Step-by-step tutorial for building capacitor bank and reactive power compensation panel
Design of reactive power compensation panel is much different and not that simple like standard distribution panel. When dealing with such panels, there are dozen of parameters to specify and… Read more
This Is Why HVDC Transmission System Beats HVAC In These Essential Applications
For the most part, electric power is transmitted worldwide by means of ac. However, there are certain applications where dc transmission offers distinct economic and/or performance advantages. These applications include… Read more
Protecting Motor From External Network Disturbances (Unbalance, V/Hz-ratio and Re-Energizing)
Unbalance in the supply voltage is typically due to a broken phase condition somewhere in the upstream network. This may result from single-phase fuse failure or pole discrepancy of a… Read more
The Essentials Of Substations, Electrical Equipment and Busbar Arrangements
Electrical power systems nowadays are generated, transmitted, and distributed in the form of alternating current. The electric power is produced at the power stations which are located in suitable places,… Read more
